Background: Omphalophlebitis is characterized as an omphalopathy that affects the umbilical vein. In these cases, ultrasonography can help identify the severity of abdominal lesions and guide the choice of treatment. Marsupialization of the umbilical vein is a surgical procedure indicated in cases where this vessel presents with purulent secretion up to the liver parenchyma. This report describes a case of omphalophlebitis in a calf treated by marsupialization of the umbilical vein. The preoperative and postoperative sonographic findings are also described. Case: A 4-day-old Holstein calf was attended at the Veterinary Hospital (HV) of the Universidade Federal de Goiás (UFG), Goiânia, Brazil. On physical examination, the animal was found to be apathetic, with tachycardia, tachypnea, hyperthermia, hyperemic mucous membranes, and moderate dehydration. An increase in volume was observed in the umbilical region, with local hyperthermia, firm consistency, and sensitivity to palpation. On deep palpation of the abdomen, a mass originating in the umbilical region and extending cranially was observed, leading to the suspicion of omphalophlebitis. Abdominal ultrasonography revealed external umbilical abscess and omphalophlebitis. Initially, conservative treatment with antibacterial and anti-inflammatory drugs was performed; however, there was no improvement in the clinical picture. Therefore, exploratory celiotomy was performed to remove the umbilical infectious focus. During the procedure, it was verified that the umbilical vein was dilated with a thickened wall until its insertion in the hepatic parenchyma, hence removal of the infected region through a ligature was not possible. Thus, marsupialization of the umbilical vein was performed to create a cutaneous opening for drainage of the purulent contents. In the postoperative period, antibacterial, anti-inflammatory, and analgesic drugs were administered. Dressing of the surgical wound and of the umbilical vein lumen was performed with topical polyvidone at 0.2%. Removal of the stitches was done 14 days postoperatively. Weekly ultrasonographic examinations were performed, which showed a gradual reduction in the diameter of the umbilical vein throughout the postoperative period. Thirty days after the surgical procedure, no further drainage of the purulent content was observed from the umbilical vein, and healing of the stump was demonstrated. After 7 months, a repeat ultrasonography was performed, revealing normal echogenicity and echotexture of the hepatic parenchyma and complete atrophy of the umbilical vein. Discussion: Umbilical vein marsupialization is a surgery rarely described in the literature, and no report has followed the evolution of a case by ultrasonography. The ultrasound examination of the umbilical structures was essential for the definitive diagnosis and choice of surgical treatment. Marsupialization of the umbilical vein was chosen due to the impossibility of ligature of this vessel, which presented with thickened walls and lumen filled with purulent content until its insertion into the liver. Postoperative monitoring via serial ultrasonography examinations allowed follow up of the evolution of the case and animal recovery. At the sonographic reevaluation after 7 months, the findings were unremarkable, indicating complete recovery of the patient. Umbilical marsupialization is a surgical technique that allows complete recovery of calves with severe omphalophlebitis. Ultrasonography is fundamental for the diagnosis of omphalophlebitis and in determining the best therapeutic protocol. Sonographic evaluation during the postoperative period allows follow-up of the progression of lesions in abdominal structures and helps in defining the prognosis.

ABSTRACT: Since the first reports of boar castration, the anesthesia, surgery, and especially the restraint for surgical wound management of large and strong boars may be challenging. Most frequent complications include hemorrhage, excessive edema, infection, abscess, scirrhous cord, inguinal hernia, seroma, hematoma, and death. In order to diminish those complications, we hypothesized that the pre-scrotal approach would be a successful method for orchiectomy in boars and that the complication rate would be low, facilitating post-surgical handling on the commercial swine breeding farms by the owners or handlers. Therefore, the present study aimed to describe our experience performing castration in boars using a pre-scrotal approach on farm-setting. Thirty commercial-breed male boars (weighing 255-410kg) were submitted to dissociative anesthesia protocol and local anesthesia. An 8-10cm skin incision was made cranially to the hemiscrotum, and subcutaneous tissue was bluntly dissected, reaching the tunica dartos, fascia, and vaginal tunica. Mesorchium was bluntly dissected to separate, and a double size-0 transfixion ligature was placed around the spermatic cord that was sharply transected. The procedure was repeated on the contralateral testis using the same skin incision. Short-term complication was restricted to mild scrotal edema in 12 (40%) boars. No wound exudate, surgical site infection or death related to the surgery was recorded. On the long-term follow-up (≥4 months' post-surgery), all owners stated that the boar was subsequently used as intended (slaughter after the proper boar taint withdrawal time) and their satisfaction with the low degree of difficulty in handling the post-operative care. Herein, the overall complication rate was considered low, the mortality rate was zero, and the pre-scrotal castration approach was successfully performed in all boars. These features confirm the technique as a safe procedure for orchiectomy in boars. Additionally, abolishing the daily dressing of surgical wounds required in open castration techniques, especially when surgical site infection occurs, may provide better welfare for the boars.


RESUMO: Desde os primeiros relatos de castração de cachaços, a anestesia, a cirurgia, e, principalmente, a contenção para manejo de feridas cirúrgicas de cachaços grandes e fortes podem ser desafiadoras. As complicações mais frequentes incluem hemorragia, edema excessivo, infecção, abscesso, funiculite, hérnia inguinal, seroma, hematoma e morte. A fim de diminuir tais complicações, levantamos a hipótese de que a abordagem pré-escrotal seria um método bem-sucedido para orquiectomia em cachaços e que a taxa de complicações seria baixa, facilitando o manejo pós-cirúrgico pelos proprietários ou tratadores. Portanto, o presente estudo objetivou descrever nossa experiência na castração de cachaços por abordagem pré-escrotal nas granjas comerciais de suínos. Trinta cachaços machos de raças comerciais (variação de peso de 255-410kg) foram submetidos ao protocolo de anestesia dissociativa e anestesia local. Uma incisão cutânea de 8 a 10cm foi feita cranialmente ao hemiscroto, e o tecido subcutâneo divulsionado de forma romba atingindo a túnica dartos, fáscia e túnica vaginal. O mesórquio foi separado por divulsão, e, uma ligadura de transfixação dupla com fio 0 realizada ao redor do cordão espermático, que foi seccionado. O procedimento foi repetido no testículo contralateral usando a mesma incisão na pele. A complicação de curto prazo foi restrita a leve edema escrotal em 12 (40%) cachaços. Nenhuma infecção incisional, exsudato ou morte relacionada à cirurgia foi registrada. No acompanhamento a longo prazo (≥4 meses pós-cirúrgico), todos os proprietários afirmaram que o cachaço foi posteriormente utilizado como pretendido (abate após o tempo adequado de retirada do odor de macho inteiro), e sua satisfação com o baixo grau de dificuldade nos cuidados pós-operatórios. Aqui, a taxa geral de complicações foi considerada baixa, a taxa de mortalidade foi zero e a castração por abordagem pré-escrotal foi realizada com sucesso em todos os cachaços. Essas características confirmam a técnica como um procedimento seguro para orquiectomia em cachaços. Além disso, a abolição do curativo diário das feridas cirúrgicas exigido nas técnicas de castração aberta, principalmente quando ocorre infecção, pode proporcionar melhor bem-estar aos cachaços.

Background: We report the case of 3 cows, 1 ewe, and 1 doe, with chronic mastitis and which underwent a mastectomy. All animals had a history of mastitis, edema with purulent secretion in the udder region, areas of abscess formation, fibrosis, hypogalactia, and agalactia. The animals had already been treated with systemic antibiotic therapy and anti-inflammatory drugs without response. The objective of this work is to describe the surgical and clinicopathological aspects of performing a radical mastectomy in the field in 3 cows and 1 ewe, and a partial mastectomy in a doe, with both procedures performed successfully and considered efficient to maintain the survival of the affected animals, in addition to being economically viable. Cases: In all animals reported in the study, a general and a specific clinical examination were performed, where on palpation of the udder were observed an increase in the region of the mammary apparatus, fluid fluctuation, areas of fibrosis with increased stiffness, and loss of udder functionality. In the case of the doe, there was a functional teat, which was preserved during the surgical procedure. Radical mastectomy was performed in 3 cows and 1 ewe, and the doe underwent a partial mastectomy, with preservation of the functional teat. All animals have fasted for food and water for 48 h. In cows, the anesthetic protocol consisted of 2% xylazine hydrochloride [0.15 mg/kg, intramuscularly (IM)], followed by an epidural block in the lumbosacral region with 2% lidocaine hydrochloride [10 mL]. The midazolam hydrochloride [0.1 mg/kg, intravenously (IV)] and 2% xylazine hydrochloride [0.05 mg/kg, IM] were administered to the ewe and the doe, also associated with lumbosacral epidural anesthesia with 2% lidocaine hydrochloride [5 mL]. The animals were positioned in the right lateral decubitus position and the entire abdominal and udder region were shaved and sanitized for the surgical procedures of radical mastectomy and partial mastectomy, with the use of degerming and topical povidone-iodine. The postoperative period consisted of penicillin-based antibiotic therapy associated with streptomycin [24,000 IU/kg, IM, 10 consecutive days] and flunixin meglumine [2 mg/kg, IM, 3 consecutive days] in cows; enrofloxacin [2.5 mg/kg, IM, 7 consecutive days] and flunixin meglumine [0.5 mg/kg, IM, 5 consecutive days] in the ewe; oxytetracycline [10 mg/kg, IM, 5 applications on alternate days] and flunixin meglumine [0.5 mg/kg, IM, 3 consecutive days] in the doe. In all animals, the cleaning of the surgical wound was performed daily with 10% topical Povidone-iodine and Permethrin ointment, for 14 days, when the stitches were removed. Discussion: The choice of the surgical procedure resulted in improvement of the clinical conditions and increased survival of all animals, and in the case of the doe, partial mastectomy contributed to the preservation of the functional teat, preserving its productive capacity. All anesthetic protocols used and the anatomical positioning of the animals were satisfactory for performing the procedures. Although they are techniques described in the literature with great blood loss, especially in cows, blood transfusion was not required in any of the animals. The stitches were removed 14 days after the surgical procedures, and the surgical wound was completely healed.

Background: Caudal vena cava thrombosis (CVCT) is a serious disease that affects cattle. Due to being commonly a fatal pathology, it causes economic losses for producers and national livestock. Thus, the present study describes the epidemiological, clinical, ultrasonographic imaging and pathological findings in 4 cattle with CVCT attended at the Veterinary Hospital (HV) of the Institute of Veterinary Medicine (IMV) of the Federal University of Pará (UFPA). Cases: The animals were crossbreds of the Gir x Holstein and Jersey x Holstein breeds, aged between 4 and 8 years old, raised in semi-extensive and intensive systems. The main clinical signs were pale mucous membranes, reluctance to move, markedly positive venous pulse, engorged jugular with positive stasis test, and serous to mucopurulent nasal exudation. The auscultation of the lung fields revealed tachypnea, silent areas, wheezing, and pleural friction, in addition to coughing, expiratory dyspnea, mouth breathing, and expiratory grunts. One animal had severe hemoptysis. The ultrasound examination performed on a bovine revealed a circular and dilated caudal vena cava in cross-section. Laboratory tests in 3 cattle revealed anemia, leukocytosis with neutrophil left shift, and increased liver enzymes. At necropsy, all cattle had thrombi in the hepatic segment of the caudal vena cava. In the lung, multiple abscesses and areas of parenchymal consolidation, crateriform areas, as well as thrombi in the arteries were observed. Pleural effusion and ascites were seen in all cattle. Clotted blood was seen in the trachea, bronchi, and on rumen contents of an animal. Histopathological alterations seen in the liver were centrilobular hepatocytes with frequent intensely eosinophilic cytoplasm, and pyknotic, karyorrhexic, or absent nuclei and cell borders barely distinguishable. In the lung were nodular and random formations, with a thick wall of mature connective tissue and a central area full of cellular debris, necrotic cells, and intact and degenerated neutrophils (abscesses). Discussion: The set of diagnostic tools that include epidemiology, clinical signs and clinical examinations, ultrasound, necropsy, and histopathology were efficient in the diagnosis of CVCT. The possible causes that led the animals to develop CVCT were diffuse septic pododermatitis in the medial nail of the right pelvic limb associated with traumatic reticuloabomasitis and liver abscesses. In 1 cow, it was not possible to establish the probable cause of CVCT, but for the other cattle in the present study, the probable causes are in agreement with studies that have shown that this disease can occur as a sequel to several septic conditions such as jugular phlebitis, mastitis, hoof rot, enteritis, pneumonia, traumatic reticulopericarditis, acidosis and rumen laminitis, as well as omphalophlebitis in calves. The tachypnea, serous to purulent nasal exudation, pulmonary wheezing, pleural friction, coughing, and expiratory dyspnea, usually with open mouth breathing and expiratory grunts evidenced in the animals of this study, occurred as a result of embolic abscess pneumonia. The presence of multiple lung abscesses, areas of parenchymal consolidation, crateriform foci, and thrombi in the pulmonary arteries and chronic suppurative pneumonia, found at necropsy of the animals in the present study, are related to the development of a thrombus in the caudal vena cava that detaches and embolizes and lodges in the pulmonary arteries. The histopathological findings in 1 cow are compatible with lesions found at necropsy and draw attention to embolic pneumonia and liver lesions, which, are related to thrombi in pulmonary arteries and abscesses formed from CVCT, as well as venous stasis exerted in the return circulation.

A 2-month-old male domestic shorthair cat was referred to a private veterinary clinic with a history of dyspnea and inappetence. At the clinical examination, the cat was in poor body condition, with hyperthermia and abdominal distension. No major abnormalities were observed in the thoracic radiographs or abdominal ultrasound. A complete blood count revealed leukocytosis with neutrophilia. Although no clinical diagnosis was made, the cat received support therapy, but went into cardiac arrest and died. The cat was submitted for necropsy and the main gross finding was two white nodules on the ventral surface of the thoracic vertebrae (from T1 to T4). At the cut surface, the nodules were friable and filled with yellow exudate. The epidural space of the thoracic region was filled with yellowish viscous material. Histologically, the vertebrae were partially replaced by abscess formation characterized by a necrotic center with degenerate neutrophils, surrounded by fibrous connective tissue. The epidural space was filled with degenerate neutrophils, necrotic debris, fibrin, and intralesional colonies of gram-negative short rod-shaped to coccobacillary bacteria. Bacteriologic culture yielded Pasteurella multocida. This paper describes the gross, histological, and bacteriological features of a rare case of spinal epidural empyema caused by Pasteurella multocida in a cat.(AU)

Background: The eye is an important sense organ responsible for sight. The cornea is the outermost of many eye layers,being predisposed to several lesions, some of them being frequent in small animal clinics meanwhile others are unusualand seldom reported in specialized literature. The stroma abscess is a common condition in horses, but atypical in dogs,it’s a condition in which a microperforation in the corneal epithelium allows microorganisms or a foreign body to penetratethe corneal stroma, and those become inside the cornea after a re-epithelialization, producing an intense inflammatoryresponse. Therefore, this case reports a case of deep stromal abscess in a Shih Tzu dog.Case: A 4-year-old female Shih Tzu, weighing 4.6 kg, was submitted to ophthalmic examination in which the left eyepresented an opaque yellowish-white protruding structure located on the right side, in the center of the cornea (3 o´clockposition), bulbar and palpebral conjunctival hyperemia and congestion, chemosis, blepharospasm, and a moderate amountof mucous discharge. The clinical diagnosis was stromal abscess with reflex uveitis. A differential diagnosis should includeconditions affecting the anterior part of the cornea, such as an epithelial inclusion cyst and a corneal ulcer. The inclusioncyst, contrarily to the corneal abscess, doesn’t cause pain, meanwhile, the corneal ulcer was ruled out by the FluoresceinStaining Test. The recommended treatment was surgical, through lamellar keratectomy, followed by overlapping pedicledconjunctival graft and third eyelid flap. In association with the surgical treatment, oral antibiotics, anti-inflammatory,and opioids, plus topical antibiotics and autologous serum eye drop. Seventy days post-surgery, the previously observedinflammatory signs were no longer present. In the conjunctival graft insertion site perpetuated a scar leucoma with few...

Administration of diets rich in highly fermentable carbohydrates and low fiber content can cause an imbalance between the microorganisms in the rumen with consequent ruminal acidosis. This problem can cause lesions in the rumen wall, often progressing to rumenitis. The purpose of the present was to characterize macroscopic and microscopic ruminal lesions observed in confined feedlot cattle with claw lesions or liver abscess. A total of 1060 bovines were evaluated via postmortem examination. Claw lesions were identified in 88, liver abscess in 10, and macroscopic rumen lesions in 230 bovines; furthermore, 178 rumens were characterized with hyperkeratosis, 41 with hyperemia, 9 with ulcer, and 2 with neoplasia. The 98 bovines with claw lesions and liver abscess were selected for histopathological examination. Of these, macroscopic lesions were noted in 23 and microscopic lesions in 23 animals. Of the 23 animals that presented macroscopic lesions, 10 showed the same changes observed under microscopy. Seven cases of hyperkeratosis were diagnosed in the macro and microscopic evaluation. Of the 5 cases of hyperemia verified on macroscopy, 2 cases were identified via microscopy, and 1 case of ulcer identified through macroscopy and microscopy. The microscopic evaluation of the rumens allowed the identification of lesions in animals with claw lesions that did not present macroscopic rumen alterations.


O uso de dietas ricas em carboidratos altamente fermentáveis e com baixos teores de fibras pode ocasionar desequilíbrio entre os microrganismos do rúmen com consequente acidose ruminal. Esse problema pode resultar em lesões na parede do rúmen, evoluindo com frequência para formação de ruminite. O presente estudo objetivou caracterizar lesões ruminais macroscópicas e microscópicas, observadas em bovinos confinados que apresentavam lesões podais ou abscesso hepático. Avaliou-se 1060 bovinos pelo exame post mortem. Foram encontradas lesões podais em 88 animais, abscesso hepático em 10 e lesões ruminais macroscópicas em 230 bovinos, sendo caracterizado 178 rumens com hiperqueratose, 41 com hiperemia, 9 com úlcera e 2 com neoplasia. Os 98 bovinos com lesões podais e abscesso hepático foram selecionados para realização de exame histopatológico. Desses, foram encontradas lesões macroscópicas em 23 e, microscópicas, em 23 animais. Dos 23 animais que apresentaram lesões macroscópicas, 10 tiveram as mesmas alterações verificadas na microscopia. Foram diagnosticados 7 casos de hiperqueratose na avaliação macro e microscópica. Dos 5 casos de hiperemia verificados na macroscopia, 2 casos foram identificados na microscopia e um caso de úlcera identificado na macroscopia também foi identificado na microscopia. A avaliação microscópica dos rumens permitiu identificar lesões em animais com lesões podais que não apresentam alterações macroscópicas ruminais.

Background: Due to its ocular microflora, the equine species is predisposed to develop mycotic ulcers which, when notproperly treated, can lead to the formation of a stromal abscess. A stromal abscess occurs through the introduction ofmicroorganisms into the corneal stroma. During re-epithelialization, the foreign body is encapsulated, thus creating abarrier that protects bacteria or fungi from treatment with antimicrobial medication. This framework can end up resultingin blindness due to chronic iridocyclitis, putting the animal’s vision at risk. The current work aims to report a case of corrective surgery for stromal abscess in a mare with the administration of intraoperative intrastromal fluconazole, in orderto corroborate the effectiveness of the technique.Case: A 9-year-old mare was evaluated, with the complaint that her right eye was closed and “yellowish” and that she hadalready been treated with intramuscular injectable anti-inflammatory drugs based on flunexin meglumine (Banamine® -50 mg) for 15 days, referring to a possible ulcer in the right eye. Ophthalmic screening resulted in a negative direct reflexand no threat response in the right eye. Examination of the conjunctiva showed congestion and chemosis. Examination ofthe cornea of the right eye was negative for Fluorescein and Green Lissamine tests, and opacity and corneal neovascularization were noted. The final diagnosis was a corneal abscess of probable fungal origin secondary to a keratomycosis. Afterthe consultation, complementary blood and biochemical tests were performed, which showed normal results for the speciesin question, and treatment was started with eye drops based on atropine 1% (Fagra® - 20 mL), ciprofloxacin antimicrobialeye drops (Ciprovet Colirio® - 5 mL), and antifungal eye drops based on ketoconazole...

The objective of this study was to analyze and determine the economic loss from the main causes of whole bovine carcass condemnation in slaughterhouses thatare inspected by the Federal Inspection Service in the state of São Paulo for the period from 2010 to 2019. Economic loss was calculated from multiplication of the number of whole carcasses condemned by the mean yield of meat per carcass and the mean annual price of beef. The monetary values were updated to the year 2019, using the IGP-DI [General Price Index]. The results indicated an economic loss of R$ 4.06 billion from the whole condemnation of bovine carcasses and the main causes were contamination (R$ 1.73 billion), abscess (R$ 283.20 million), urinary cyst (R$ 194.14 million), emphysema (R$ 107.00 million) and nephritis (R$ 107.52 million). The main factors associated with the whole condemnation of bovine carcasses are failures in the pre-slaughter management and in the slaughter stages, as well as nutritional disorders. Consequently, to minimize such losses in beef production in São Paulo state it is recommended to adopt good production practices and train slaughterhouse employees.(AU)

Background: Spinal epidural empyema (SEE) is a rare disease in cats that has been described as a cause of severe compressive myelopathy. It is characterized by accumulation of purulent exudate in the form of an abscess in the epidural space. Neurological signs range from spinal hyperesthesia to rapidly progressive paraplegia and may be associated with systemic signs. Spinal lymphoma is the most common neoplasm affecting the central nervous system of cats and can mimic different neoplasms and non-neoplastic diseases, such as SEE. The aim of this study is to report a case of SEE in a cat and highlight the similarities in neurological, laboratory, and imaging findings between this disease and spinal lymphoma. Case: A 8-month-old male neutered mixed-breed cat was referred to the Veterinary Medical Teaching Hospital (HVU) of the UFSM with acute, non-progressive paraplegia. On neurological examination, the patient was paraplegic with no nociception, normal spinal reflexes, increased muscle tone in the pelvic limbs, absence of cutaneous trunci reflex, and spinal hyperesthesia between T13-L1, demonstrating injury in the T3-L3 spinal cord segment. The differential diagnoses included acute spinal cord trauma, neoplasm (lymphoma), and infectious diseases. Hemogram showed lymphocytosis (8062/µL); the biochemical examinations were unremarkable. Tests for antibodies against feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) antigens were negative. Simple radiography, abdominal ultrasonography, and cerebrospinal fluid findings were also normal. Myelography showed left dorsolateral extradural spinal cord compression from T12 to L1. Based on these findings, the presumptive diagnosis was spinal lymphoma and chemotherapy was initiated. After 2 days, the animal began to show hyporexia, adipsia, vomiting, and diarrhea, in addition to an increase in subcutaneous volume in the thoracolumbar region. Antibiotic therapy was initiated; however, the patient died. Necropsy revealed an abscess in the left dorsolateral extradural space at T12-T13 and T13-L1. Bacterial cultures revealed the presence of Neisseria spp. that was resistant to various antibiotics. On the basis of these findings, the animal was diagnosed with SEE. Discussion: This case report aims to inform veterinarians about the diagnosis of SEE. SEE is a rare condition in cats compared to spinal lymphoma; however, their presentation is similar. Even in imaging examinations, such as magnetic resonance imaging, it is not possible to differentiate between these 2 conditions. The evolution of clinical signs made the diagnosis of the present case difficult since it was acute and not progressive. All cases of SEE reported in the literature were progressive, acute, or chronic. Although testing for FeLV was negative, only 56% of cats with spinal lymphoma test positive for this virus. Clinical signs reported by the owner after the start of chemotherapy may be related to adverse effects, such as immunosuppression, which led to worsening of the condition, culminating in the appearance of a subcutaneous abscess. Subsequently, SEE was suspected; however, surgical decompression was not performed as the animal died soon after. The authors of this report reinforce the need for a definitive and non-presumptive diagnosis of spinal lymphoma to initiate chemotherapy because it mimics different neoplasms and non-neoplastic diseases, such as SEE. Surgical removal of the compressive mass in the spinal cord and histopathological analyses are necessary.

Slaughter condemnations are important sources of information on cattle health and handling. The aim of this study was to evaluate the main causes of condemnation of cattle slaughter under the state sanitary inspection by the Diretoria de Inspeção de Produtos de Origem Agropecuária (DIPA) of Agência de Defesa Agropecuária da Bahia (ADAB), in Bahia, Brazil. A retrospective data of all cattle slaughtered from 2012 to 2019 was obtained from DIPA ­ ADAB. During this period, 4,635,615 cattle were slaughtered and 1,452,472 (31.33%) condemnations were registered to have occurred at varying levels in all regions of the state. The more condemned organs were kidneys and lungs; and the main causes of condemnation were nephritis (11.79%), congestion (11.20%), emphysema (10.72%), blood aspiration (8.36%), renal cysts (5.75%), and abscesses (5.71%). However, other condemnation causes such as cysticercosis, fasciolosis, and tuberculosis were observed at lower rates. Results showed that the main causes of condemnation of cattle slaughter were not related to zoonotic diseases instead were more involved in partial condemnation of organs.(AU)


As condenações no momento do abate dos animais são importantes fontes de informação sobre a saúde e o manejo do rebanho. Por isso, o objetivo deste estudo foi avaliar as principais causas de condenações em bovinos abatidos sob sistema de inspeção estadual da Diretoria de Inspeção de Produtos de Origem Animal (DIPA) da Agência de Defesa Agropecuária da Bahia (ADAB), no estado da Bahia, Brasil. O estudo retrospectivo obteve os dados da DIPA ­ ADAB e analisou os dados de animais abatidos entre 2012 e 2019. Nesse período, foram abatidos 4.635.615 bovinos e 1.452.472 (31,33%) de condenações foram observadas em todas as regiões variando em diferentes níveis. Os órgãos mais condenados foram rins e pulmões e as principais causas de condenação encontradas foram nefrite (11,79%), congestão (11,20%), enfisema (10,72%), aspiração de sangue (8,36%), cistos renais (5,75%) e abscessos (5,71%). No entanto, outras causas com taxas de condenação menores como cisticercose, fasciolose e tuberculose também foram observadas. Os resultados mostram que as principais causas de condenação não estão relacionadas com doenças com potencial zoonótico e levam a condenações parciais das vísceras acometidas.(AU)

Purpose: To analyze the effects of Anacardium occidentale Linn on the healing of skin wounds. Methods: Twenty Wistar male rats were distributed into four groups (with five animals each one): negative control group (NCG), treated with saline solution; cashew tree group (CG), treated with hydroalcoholic extract of the bark of A. occidentale Linn; manipulated cashew tree group (MCG), with the ointment of extract of the bark of A. occidentale Linn; positive control group (PCG), treated with sunflower oil. All animals were examined daily, observing the macroscopic aspects of the surgical wound. Hematoxylin-eosin staining was used for tissue morphology analysis and Masson's trichrome for better collagen fiber characterization. Results: On day 7, the MCG group had the expansion of the surgical wound covered by crust, exceeding the initial limits. On day 21, the wounds were observed to be completely closed and epithelialized in the NCG and CG groups. PCG and MCG still had remnants of crusts on the wound. The NCG was the only one not to present an abscess in histopathological analysis. Conclusions: There was a prolongation of the healing phase of the animals treated with the extract, and the animals in the NCG showed a better outcome by histological analysis.

Brazil is a major beef producer and exporter. However, carcasses with anatomopathological alterations can cause economic losses by being the target of some type of condemnation or being conditionally used. The objective of this research work was to analyze the anatomopathological changes and destinations of bovine carcasses in Brazil, from March 30, 2017, to December 31, 2019. Data were collected through the Management Information System of the Federal Inspection Service (SIGSIF), made available online by the Brazilian Ministry of Agriculture, Livestock and Supply (MAPA). It was observed that 67,456,321 bovines were slaughtered, and 2.0% of the carcasses were condemned or conditionally used. The southern region of the country had the highest occurrence of anatomopathological alterations in the carcasses (4.5%), while the Northeast had the lowest (0.1%). The main criterion for judging carcasses in the country was partial condemnation, with 81.7% of judgments established. The main causes of condemnations and conditional use were contamination (31.5%), cysticercosis (21.2%), contusion (11.3%), adenitis (7.4%) and abscess (6.5%). It was noted that a standardization of records in the SIGSIF would be important for a clearer collection of information and for the recording itself by slaughterhouses. The importance of veterinary inspection to guarantee the commercialization of safe meats to consumers was evidenced.


O Brasil é um grande produtor e exportador de carne bovina. Entretanto, carcaças com alterações anatomopatológicas podem causar prejuízos econômicos por receberem algum tipo de condenação ou aproveitamento condicional. O objetivo do trabalho foi analisar as alterações anatomopatológicas e os destinos dados as carcaças bovinas no Brasil, no período de 30 de março de 2017 a 31 de dezembro de 2019. Os dados foram coletados por meio do Sistema de Informações Gerenciais do Serviço de Inspeção Federal (SIGSIF), disponível online por meio do MAPA. Observou-se que foram abatidos 67.456.321 bovinos e 2,0% das carcaças foram condenadas ou aproveitadas condicionalmente. A região Sul do país obteve maior ocorrência de alterações anatomopatológicas nas carcaças (4,5%), enquanto o Nordeste obteve a menor (0,1%). O principal critério de julgamento de carcaças no país foi a condenação parcial, com 81,7% dos julgamentos estabelecidos. As principais causas de condenações e aproveitamento condicional foram contaminação (31,5%), cisticercose (21,2%), contusão (11,3%), adenite (7,4%) e abcesso (6,5%). Notou-se que a padronização dos registros no SIGSIF seria importante para coleta mais clara das informações e para o próprio registro por parte dos abatedouros. Evidenciou-se a importância da inspeção veterinária para garantir a comercialização de carnes seguras aos consumidores.

Oral diseases are limiting to health, welfare, and conservation practices, especially in the case of endangered animals. In this retrospective study, a survey on oral health-related conditions noted in the clinical records for 261 deer comprised in an ex situ population of the Marsh Deer Conservation Center (CCCP) over 30 years (1990-2020) was carried out. Of these, 49 (18.77%) marsh deer (31 females - 63.27% and 18 males - 36.73%) had clinical oral affections; the affected deer's mean age was 8.9 years. Logistic regression analysis was performed, and the variable age was significantly associated with the presence of dental affections. Thus, with a change in the age category, a deer had eight times the chance of manifesting oral affections; therefore, age can be considered a risk factor for the manifestation of oral affections in the species. Increased facial volume (65.3%), accumulation of food in the mouth (36.7%), tooth loss (22.4%), fistulas (22.4%), mucosal or palatal lesions (22.4%), tooth wear (20.4%), and tooth root exposure (18.3%) were the most frequently recorded lesions. The relatively high occurrence of oral affections in Blastocerus dichotomus reiterates the importance of oral health care when deer are kept in human care.


As doenças bucais são limitantes para as práticas de saúde, bem-estar e conservação, especialmente no caso de animais ameaçados de extinção. Neste estudo retrospectivo, realizou-se um levantamento sobre condições relacionadas à saúde bucal observadas nos registros clínicos de 261 cervídeos que compunham uma população ex situ do Centro de Conservação do Cervo-do-Pantanal durante um período de 30 anos (1990-2020). Destes, 49 (18,77%) cervos-do-pantanal (31 fêmeas (63,27%) e 18 machos (36,73%)) apresentavam afecções clínicas bucais; e a idade média dos cervídeos afetados foi de 8,9 anos. Realizou-se a análise de regressão logística e a variável idade mostrou associação significativa com a presença de afecções dentárias. Assim, com a mudança de categoria de idade, um cervídeo teve oito vezes mais chances de manifestar afecções bucais; portanto, a idade pode ser considerada como fator de risco para manifestação de afecções bucais na espécie. Aumento de volume facial (65,3%), acúmulo de alimentos na boca (36,7%), perda dentária (22,4%), fístulas (22,4%), lesões nas mucosas ou palatinas (22,4%), desgaste dentário (20,4%) e exposição de raiz (18,3%) foram as lesões mais registradas. A ocorrência relativamente alta de afecções bucais em Blastocerus dichotomus reitera a importância dos cuidados com a saúde bucal quando os cervídeos são mantidos sob cuidados humanos.

Lagoquilascariasis is a zoonotic disease caused by a nematode parasite of the genus Lagochilascaris (Family Ascarididae), with the ingestion of contaminated rodents being the main source of infection. The main clinical signs are dysphagia and the presence of ulcerated nodules in the cervical region. The objective was to describe a case of lagaroquilascariasis in a domestic cat, in the city of Caxias do Sul / RS. A young adult male feline, without defined breed presented lethargy, dehydration, bilateral fistulas in the oropharynx cavity, right eyeball with exophthalmos, corneal opacity, third eyelid prolapse and periocular ulcerated skin lesion in the upper medial region. The diagnosis was made through the visualization and microscopic identification of the parasite Lagochilascaris minor and coproparasitological examination with the presence of eggs. Treatment was based on the use of doramectin and sanitary measures. According to the current literature, there are few reports of lagoquilascariasis in felines with clinical presentation similar to this case, since the most common is the formation of an abscess in the neck region. Morover, it is the first case described in the municipality, thus contributing to the epidemiology of the disease.


A lagoquilascaríase é uma doença zoonótica causada por um parasita nematoide do gênero Lagochilascaris (família Ascarididae), sendo a ingestão de roedores contaminados a principal fonte de infecção. Os principais sinais clínicos são disfagia e presença de nódulos ulcerados em região cervical. O objetivo deste trabalho foi descrever um caso de lagoquilascaríase em um felino doméstico, na cidade de Caxias do Sul/RS. Um felino, macho, sem raça definida, adulto jovem, apresentou letargia, desidratação, fístulas bilaterais em cavidade orofaringe, globo ocular direito com exoftalmia, opacidade de córnea, prolapso de terceira pálpebra e lesão cutânea ulcerada periocular em região superior medial. O diagnóstico foi realizado por meio da visualização e identificação microscópica do parasita Lagochilascaris minor e de exame coproparasitológico com presença de ovos. O tratamento baseou-se no uso de doramectina e de medidas sanitárias. De acordo com a literatura atual, existem poucos relatos de lagoquilascaríase em felinos com apresentação clínica semelhante a este caso, visto que o mais comum consiste na formação de abscesso na região de pescoço. Além disso, é o primeiro caso descrito no município, contribuindo, assim, para a epidemiologia da doença.

Background: Penile fracture is a pathology of young cattle that perform precocious and disordered breeding. The incompatibility of height between males and females and sodomy between males cause a great pressure on the sigmoid flexure and retractor muscle of the penis, which are the main causes and sites of organ injury. This study aimed to describe the epidemiological and pathological aspects of penile fractures observed in young bulls raised in pre-export feedlots (PEFs) in southern Brazil. Cases: In 2 PEFs located in the municipalities of Pelotas (property 1) and Capão do Leão (property 2), 3 male cattle [1 from property 1 and 2 from property 2] presented subcutaneous edema in the foreskin and perineum, associated with dysuria. The evolution of the clinical picture was approximately 20 days in all cases, with evolution to death. The bovine necropsied on property 1 had an increased volume and inguinal edema, involving the penis and scrotal sac. Necrosis of the subcutaneous tissue and local musculature was also observed. The testicles were surrounded by the necrotic tissue, and the right testis was swollen, with flaccid parenchyma adhering to the tunica albuginea. In the necropsy of 1 bull from property 2, an increase in the inguinal volume was observed, with an extensive area of necrosis and edema extending from the prepuce to the caudal musculature of the scrotal sac. There were also marked varicosis in the sigmoid flexure and necrosis of the adjacent region, without the involvement of the corpus cavernosum. During the necropsy of the 2 young bulls, fragments of organs from the abdominal, thoracic, and brain cavities were collected and fixed in 10% buffered formalin. From the bull of the property 2, an anatomical piece consisting of the penis, prepuce, and testicles was also collected and fixed in 10% buffered formalin. After 48 h, the tissue samples were cleaved, embedded in paraffin, cut into 3-µm-thick sections, and stained using hematoxylin and eosin (HE). A histological evaluation of the penile lesions in both cattle revealed intense hemorrhage, congestion, and necrosis of the muscles and tissues adjacent to the corpus cavernosum. In addition to areas of dystrophic calcification, neutrophil and macrophage infiltration was also observed. In the bull from the property 1, an intense edema and proliferation of fibrous tissue surrounding the urethra were noted. There were also marked tubular degeneration and intense infiltration of neutrophils, lymphocytes, and macrophages in the inner portion of the tunica albuginea. Discussion: In the present cases, the diagnosis was based on epidemiological data associated with clinical signs and pathology. The macroscopic lesions observed were probably due to the involvement of blood vessels adjacent to the penis, which suffered trauma during sodomy mating among cattle. These lesions have been described in other reports of this pathology and in diseases, such as acropostitis-phimosis, fibropapilloma of the glans, preputial abscess, and urolithiasis, and the differential diagnosis of these diseases must be carried out, as they have different etiologies. In the bulls of the present study, no lesions were observed in the corpus cavernosum, and this condition was attributed to the presence of varicosis and accumulation of urine in the prepuce, due to the difficulty in exposing the penis. Histologically, there were intense hemorrhage, congestion, and necrosis of the muscles and tissues adjacent to the corpus cavernosum, with the infiltration of neutrophils and macrophages, and areas of dystrophic calcification. The presence of necrotic lesions in tissues adjacent to the penis may be related to hypoxia, vascular lesions, or the action of chemical elements present in the urine. In both cases, vascular lesions were present, which were attributed to the main triggering factor for the disease.

This study describes, through a retrospective study, the epidemiological and clinical-pathological findings of compression in the central nervous system (CNS) of buffaloes. The study includes observations made in 15 animals from 1998 to 2021 by reviewing the clinical records of animals with compressive injuries of the CNS treated at the Veterinary Hospital of the Veterinary Medicine Institute of the Federal University of Pará. The animals treated with clinical signs compatible with CNS compressive lesions were subjected to general and specific clinical examinations of the nervous system. Blood samples were collected from four animals for complete blood counts, and cerebrospinal fluid (CSF) samples were collected from three animals for physical evaluation. Thirteen animals were necropsied. The age range of the affected animals ranged from four months to 11 years of age, with a greater frequency over age 12 months (80%, 13/15). The most affected vertebral segment was between T3 and L3 (60%, 9/15), followed by brain injury (20%, 3/15), the L4-S2 segment (13.3%, 2/15) and the C1-C5 segment (6.7%, 1/15). The clinical findings varied according to the location of the lesion. The necropsy findings revealed paraypophyseal abscess in the brainstem and vertebral body, subarachnoid hematoma, lymphoma and vertebral fractures. The performance of a thorough clinical examination of the CNS combined with the necropsy findings was important to characterize the clinical picture and to locate the cause and the affected CNS segments in the buffaloes studied. It is important to include CNS compressive lesions among the neurological diseases of buffaloes.


Esse trabalho descreve, através de estudo retrospectivo, os achados epidemiológicos e clínico-patológicos de compressão no sistema nervoso central (SNC) de bubalinos. O estudo compreendeu as observações realizadas em 15 animais, durante os anos de 1998 a 2021, por meio da revisão dos arquivos de fichas clínicas de animais com lesões compressivas no SNC atendidos pelo Hospital Veterinário do Instituto de Medicina Veterinária da Universidade Federal do Pará. Os animais atendidos com sinais clínicos compatíveis com lesões compressivas no SNC foram submetidos a exames clínicos geral e específico do sistema nervoso. Foram coletadas amostras de sangue de quatro animais para realização de hemograma e amostras de líquido cefalorraquidiano (LCR) de três animais para avaliação física. Foram necropsiados 13 animais. A faixa etária dos animais acometidos variou de quatro meses a 11 anos de idade, com maior frequência na faixa acima de 12 meses (80%, 13/15). O segmento vertebral mais acometido foi entre T3-L3 (60%, 9/15), seguida por lesão no encéfalo (20%, 3/15), pelo segmento L4-S2 (13,3%, 2/15) e pelo segmento C1-C5 (6,7%, 1/15). Os achados clínicos variaram de acordo com a localização da lesão. Os achados de necropsia revelaram abscesso parahipofisário, no tronco encefálico e no corpo da vértebra, hematoma subaracnoidea, linfoma e fraturas vertebrais. A realização de um minucioso exame clínico do SNC associado aos achados de necropsia foram importantes para caracterizar o quadro clínico e localizar a causa e os seguimentos acometidos do SNC nos búfalos estudados. Torna-se importante incluir as lesões compressivas do SNC entre as enfermidades neurológicas dos bubalinos.

Resumo

Cases of periodontitis in sheep from the Agreste and Zona da Mata regions of Pernambuco, Northeastern Brazil, are described. Information on breed, age and sex of affected animals as well as clinical and pathological aspects of the disease were obtained during farm visits. Fifteen animals from a total of 450 Santa Inês sheep, aged between three and twelve years, showed low body condition score, dull coat, and difficulty in feeding followed by pain on palpation of the mandibular region. Physical examination of the oral cavity of affected animals and post mortem findings of slaughtered individuals revealed varying degrees of periodontitis, wear, fracture, mobility, and loss of teeth associated with gingival retraction, presence of biofilm and food packing between incisors, premolars and molars teeth. Increased mandibular volume was observed in eight animals and, in two of them, an abscess fistula, exclusively in mandibular teeth. The occurrence of periodontitis in sheep had not been recorded until now in Northeastern Brazil and, thus, this is the first description of cases in the region.


Descrevem-se casos de periodontite em ovinos provenientes das regiões do Agreste e Zona da Mata de Pernambuco, Nordeste do Brasil. Informações sobre raça, idade e sexo dos animais afetados bem como os aspectos clínicos e patológicos dos surtos foram obtidos a partir de visitas às propriedades e são reportados. 15 animais de um total de 450 ovinos da raça Santa Inês, com idade entre três a doze anos de idade manifestaram baixa condição corporal, pelagem sem brilho e dificuldade de alimentar-se, acompanhado de dor à palpação na região mandibular. O exame físico da cavidade oral dos animais afetados e os achados post mortem de indivíduos abatidos revelaram graus variados de periodontite, desgaste, fratura, mobilidade e perda dentária, associados a retração gengival, presença de biofilme e compactação de resíduos alimentares entre os dentes incisivos, pré-molares e molares. Em oito animais havia aumento de volume mandibular e em dois deles observaram-se abscessos fistulados que ocorreram exclusivamente nos dentes mandibulares. A ocorrência de periodontite em ovinos não têm sido registrada no Nordeste do Brasil, sendo estes os primeiros casos descritos na região.
