Epizootiology of canine distemper in naturally infected dogs in Goiânia, Brazil / Epizootiologia da cinomose em cães naturalmente infectados em Goiânia, Brasil

Although the epizootiological profile of canine distemper in Goiânia is unknown, there is clinical evidence for a high incidence of canine distemper virus (CDV) infection among dogs. Therefore, this study determined the epizootiological characteristics of canine distemper in naturally infected dogs. Data of 46 dogs that tested positive for the CDV based on immunochromatography or reverse transcription-polymerase chain reaction were collected. Data on the sex, breed, age, and vaccination status were obtained from these dogs, and extraneural and neural sign analyses were performed. Although, the infected dogs belonged to both sexes, different breeds, and different age groups, a greater proportion of cases were seen in adults (1-6 years), undefined breeds, and unvaccinated dogs. Among the CDV-positive dogs, 10.87% had been vaccinated. In addition, 4.35% showed neural signs, 8.69% showed extraneural signs, and 86.96% showed both. High lethality was observed, with viral antigen and/or DNA detected in 82.61% dead dogs. Only 8.70% of the total CDV-infected dogs remained alive at the time of their assessment.

Embora o perfil epizootiológico da cinomose canina em Goiânia seja desconhecido, há evidencia clínica para alta incidência da infecção pelo vírus da cinomose (CDV) nos cães. Este estudo objetivou determinar as características epizootiológicas da cinomose em cães naturalmente infectados. Dados de 46 cães positivos por imunocromatografia ou reação em cadeia da polimerase via transcriptase reversa para o CDV foram coletados. Dados sobre sexo, raça, idade, estado vacinal foram obtidos desses cães, e os sinais extraneurais e neurais foram analisados. Animais de ambos os sexos, diferentes raças e idades foram acometidos. A maior proporção de casos foi vista em adultos (de um a seis anos), sem raça definida e não vacinados. Dentre os cães positivos, 10,87% haviam sido vacinados. Em adição, 4,35% apresentaram sinais neurais, 8,69% sinais extraneurais e 86,96% mostraram ambos. Alta letalidade foi observada, com o antígeno viral e/ou DNA identificado em 82,61% dos cães que foram a óbito. Apenas 8,7% dos cães infectados permaneceram vivos até o momento da avaliação.

Distiquíases em gatos / Distichiasis in cats

Background: Distichiasis is a disease that is rare in cats, but very common in dogs. The term distichiasis may be controversial when used in the feline species, given that they do not possess true cilia, but rudimentary hair along the superior palpebra. The patients may be asymptomatic, though some show signs of ocular discomfort and ulcerative keratitis. The diagnosis is reached through an ophthalmological exam, and the treatment consists of the removal of the cilium with or without its hair follicle. With this work, we aim to report a series of cases of distichiasis in cats, as it is an uncommon anomaly, and has the potential to cause ocular discomfort in cats. Cases: Two mobile services of veterinary ophthalmology, one in the federal district of Brasília (DF) and the other in the municipality of Valinhos (SP), attended to 9 cats over a period of 5 years (2018 to 2022). The cats (n = 9) attended are of an undefined breed with ages varying from 10 months to 9 years, with an average of 3.9-year-old. The number of distichiasis presented by the animals was classified according to their quantity, being categorized as a mild grade when there was a single cilium, moderate grade when there were 2 to 4 cilia, and severe grade when there were more than 5 cilia. The highest incidence of distichiasis in this study was in males (78%) while females accounted for (22%) of the cases. The clinical changes reported by the owners consisted of signs of ocular discomfort (photophobia, blepharospasm, and periocular itching), ocular discharge and ocular redness. In the ophthalmological evaluations, blepharospasm (22%), serous to mucosal secretion (56%), chemosis (22%), mild (44%) to moderate (11%) conjunctival hyperemia, and ulcerative keratitis (22%) were observed. Distichiasis was more frequent affecting both eyes (56%), while in only (44%) of cases it affected the left eye only. The highest occurrence of cilia was identified in the upper palpebra (78%). Distichiasis was found more often in the temporal palpebral portion (78%), and in 2 patients the identification was more challenging since these cilia lack pigmentation. Single cilium affected (44%) of patients, while 5 cats had multiple distichiasis (56%). A total of 29% of the cats had a mild grade, whereas 14% had a moderated grade, and 57% had a severe grade. The treatments performed consisted of manual epilation (ME) and electroepilation (EE). ME was carried out in 56% of the cats, with relapses occurring in 80% of the patients, while 44% of the cats submitted to EE had a relapse in 20% of the cases. Discussion: Distichiasis is an inherited disorder very frequent in dogs, but considered uncommon in cats. Its causative factor is still unknown, as is its mode of inheritance. In distichiasis therapy, epilation, electroepilation, electrolysis, diode laser, cryotherapy and surgical palpebral resection techniques are referred to as procedures. Among the treatments used in this study, we observed a lower incidence of relapse with the electroepilation technique, which proved to be a viable and successful therapeutic modality. This series of cases shows that perhaps this disorder is much more frequent than what has been reported in the literature, being sometimes underdiagnosed and consequently underreported. Therefore, distichiasis in cats should be considered as a differential diagnosis in patients with clinical signs of ocular discomfort and ulcerative keratitis.

Metastatic intranasal mastocytoma in a dog

Background: Mast cell tumors (MCTs) are neoplasms originating from mast cells, which can be well or poorly differentiated. They are considered the most commonly diagnosed malignant cutaneous neoplasm in dogs; however, intranasal forms are still little reported. Thus, this study seeks to report a case of unilateral intranasal MCT exhibiting submandibular lymph node metastasis. Case: A 11-year-old-and-4-month-old dog of undefined breed (UB), weighing 41 kg, was referred to the Veterinary Medical Teaching Hospital of the University of Passo Fundo (UPF), in the state of Rio Grande do Sul, Brazil. Presenting a clinical history of bilateral purulent nasal secretion, accompanied by sneezing in the two months prior to admission, in addition to vomiting and diarrhea. Auxiliary tests were requested, including skull X-ray, cytology of the nasal cavity with a swab, and collection of material from the submandibular lymph node directly through cytology with a needle. Cytological findings from the right nasal cavity were consistent with mast cell tumors (MCTs). Cytological analysis of the left nasal cavity was compatible with dysplasia/cellular reactivity. A heterogeneous population of cells was detected on cytology of the right submandibular lymph node. These findings were consistent with MCT lymph node metastasis. Skull radiography showed an increase in both opacity and soft tissue extension, surpassing the palate, from the canine tooth through the caudal region of the maxillary sinuses to the last molar, without bone destruction. The dog was then admitted for an abdominal ultrasound, which showed no changes in the spleen or liver. The leukocyte count showed mild lymphopenia and the presence of reactive lymphocytes. Through the buffy coat, the presence of rare round cells, compatible with circulating mast cells, was detected. Due to the biological behavior of the neoplasm and its anatomical location, the established therapy was based on the use of vinblastine and prednisolone. The patient did not show any clinical improvements. In a joint decision with the patient's guardian, the dog was euthanized. Discussion: Intranasal MCTs commonly present progressive and intermittent unilateral epitaxis, mucopurulent nasal discharge, dyspnea, and ocular discharge. Several anatomical sites were associated with more aggressive neoplastic phenotypes; those with an unfavorable prognosis were mainly those present in the oral and intranasal mucosa. Cytopathological examination is considered a highly sensitive method for the diagnosis of MCTs. Metastases are present in more than 90% of mucosal MCTs, usually affecting regional lymph nodes and associated with a poor prognosis. Radiography is considered a useful test in determining the size and location of tumors in the nasal cavity. Chemotherapy plays an important role in the treatment, especially in cases like the one described in this report, in which surgical excision is not possible due to the anatomical location of the neoplasm. Intranasal MCTs are uncommon in dogs. In this case, he presented aggressive, metastatic behavior and a poor response to antineoplastic therapy. Furthermore, due to the location of these tumors, they may be clinically similar to a number of other upper respiratory tract diseases, posing a diagnostic challenge. Therefore, it is essential that the search for differential diagnoses be carried out through auxiliary tests, such as cytology and imaging.

Esporotricose felina na região periocular - eficácia do tratamento com itraconazol / Feline sporotrichosis in the periocular region - successful treatment with itraconazole

Background: Sporotrichosis is a zoonotic disease caused by a dimorphic fungi of the Sporothrix schenckii complex. It isan emerging zoonosis with worldwide distribution, thus of great importance to public health. The infection occurs fromtraumatic inoculation of the fungus in the human skin from contaminated plants and soils and through bites or scratchesof infected animals. The occurrence of sporotrichosis has been related to zoonotic transmission, especially by domesticfelines. This work aims to report the successful use of itraconazole as monotherapy in a case of localized feline sporotrichosis and highlight the effectiveness of cytology in its diagnosis.Case: A 1-year-and-4-month-old spayed female cat undefined breed, weighing 3.1 kg, was referred to the VeterinaryMedical Teaching Hospital of the Universidade Estadual de Maringá (UEM), city of Umuarama, presenting a serosanguinous ulcerative lesion located in the left periocular region The clinical picture of the patient progressed over 3 months.Treatments with antibiotic therapy, corticosteroids, and surgical procedures were conducted, without clinical improvement. A new lesion in the distal portion of the thoracic limb emerged, proving that the disease remained in progression.Hematological exams were performed, among them hemogram, renal and hepatic biochemical analyses, SNAPS to identifythe feline immunodeficiency virus feline leukemia virus (FIV/FeLV), and cytology of the lesion through imprints. Thehematological results were all within the normal standards for the species. Cytology showed a large amount of oval andfusiform structures phagocyted by polymorphonuclear cells, free at the bottom of the slide, compatible with Sporothrixspp. The treatment administered was itraconazole (100 mg/cat), orally administered every 24 h, cefovecin sodium 8 mg/kg,subcutaneous, single dose, topical use of...

Primary intestinal fibrosarcoma in cats

Background: Fibrosarcomas are malignant neoplasms of mesenchymal origin and can have different symptoms depending on the species, age, location and etiopathogenesis. Intestinal tumors in domestic cats are common and the small intestine is the most common site; however, fibrosarcomas are rare in the intestine of all animal species. This work reports intestinal fibrosarcoma in 2 domestic cats and aims to clarify and present information concerning this neoplastic type in the gastrointestinal tract of this species. Cases: We report 2 cases of intestinal fibrosarcoma in domestic felines (Felis catus). Cat 1. A 14-year-old female Persian breed, domestic cat, was taken to the Feline Sector of the Veterinary Hospital of Small Animals (HVPA) of the Federal Rural University of Rio de Janeiro (UFRRJ). The main complaint was chronic constipation and rectal prolapse. The clinical examination revealed an ulcerated mass, measuring 4.0 cm x 1.7 cm. Cat 2. A 10-year-old female undefined breed, domestic cat, was taken to the private clinic. The main complaint was diarrhea with bloody and rectal prolapse. The clinical examination revealed nodule measuring 2.5 cm in diameter. The surgical option decided upon was to use the rectal pull-through technique in both animals. The patients had no trans-surgical or postoperative complications. The material collected during the surgical interventions was analyzed macroscopically and fixed in 10% buffered formalin for 24 h and then sent to the Histopathology Laboratory of the Pathological Anatomy Sector (SAP) at UFRRJ for the cat 1 and in private laboratory for the cat 2. After fixation, it was cleaved for routine microscope exam using Hematoxylin and Eosin (HE) stains and for the histochemical method of Masson's Trichrome staining technique. Complementary immunohistochemistry tests and electron microscopy were also performed. The patients were followed up clinically, showing complete remission of the clinical signs and survival for approximately 1 year after the neoplastic resection. Discussion: There are few reports of intestinal fibrosarcomas in veterinary medicine, therefore, little is known about racial predilection, age, sex or biological behavior. As far as these authors know, this is the 6th and 7th report of this neoplasm with a primary site in the large intestine in this species. The morphological diagnosis of fibrosarcoma is relatively simple, whereas, in some cases the differential diagnosis for tumors of the peripheral nerve sheath, leiomyosarcomas and gastrointestinal stromal tumor (GIST) can be extremely difficult. The immunohistochemistry technique in these cases may not be particularly useful. The fibrosarcoma diagnosis was also confirmed by electron microscopy since no evidence was found that could lead to a neuronal origin, thus excluding tumors such as neurofibrosarcoma and schawnoma, corroborating the immunohistochemical examination. The surgical management of tumor resection with wide safety margins (minimum 2 cm) remains the "gold standard" therapy for dealing with fibrosarcomas since they have a low response rate to chemotherapy and radiotherapy and the use of these therapies as an adjuvant is controversial. The advantages of this technique are related to the surgical time, simplicity, easy access and reduction in the risk of abdominal contamination. Histopathological, immunohistochemistry and electron microscopy evaluations were sufficient to enable the diagnosis of an intestinal fibrosarcoma in both cats. The occurrence of this neoplasm with intestinal involvement in the feline species is rare; therefore, this description is important as it provides information about epidemiology, associated signs, differential diagnoses, biological behavior, treatment and prognosis.

Quimiodectoma em cão / Chemodectoma in a dog

Background: The chemodectoma is a rare neoplasm that originates from chemoreceptors located mainly in the aortic body,and carotid body and sinus, and responsible for detecting variations in blood pH, oxygen pressure and carbon dioxide. Dogsof brachiocephalic breeds and aged between 7 and 15 years have greater propensity. A neoplasm involves infiltrative growthin the vessels at the heart base, which leads to Congestive Heart Failure (CHF). The definitive diagnosis is performed byhistopathological and/or immunohistochemical examination. The aim was to report a case of chemiodectoma in a dog,showing the disease’s clinical characteristics.Case: A 13-year-old male undefined breed dog was examinated in the medical clinic of small animal of Veterinary Hospital,Federal Rural University of Pernambuco (UFRPE) with respiratory effort, hyporexia, and edema in face, cervical, ventralthorax and thoracic limbs, with thirty days evoluted. About physical examination, we observed cachexia, orthopneic position, cyanosis and edema with a positive Godet sign, as well as 8% dehydration degree. Thoracic auscultation presentedmixed dyspnea and muffled heart sounds. Chest radiography detected an radiopacity increase in pulmonary section andmetastatic neoplastic process associated with pleural and pericardial effusion. Fluid therapy with lactated ringer and posteriorthoracentesis in the right hemithorax region was performed for greater respiratory comfort for the patient. Hematologicalcount and biochemical profiles stated normochromic normocytic anemia, relative and absolute lymphopenia, thrombocytopenia, as well as increased alanine aminotransferase (ALT) and aspartate aminotransferase (AST). The patient diedafter 12 hours when was submitted to necroscopic examination and histopathological evaluation. An infiltrative tumor ofcardiac base was observed invading the light of the right atrium, obstructing the venous return, as well as a large thrombus...

Protein supplementation for sheep fed with tropical forage / Suplementação proteica para ovinos alimentados com forragem tropical

The effects of increasing levels of protein supplementation (50, 100, 150 and 200 animal per day) and mineral salt on feed intake, nutrient digestibility and ingestive behavior of sheep consuming tropical forage (Pennisetum purpureum Schum) were evaluated. Five non-castrated crossbred lambs (½ Santa Inês x ½ undefined breed) with average initial body weight of 35.0 kg (± 4.40 kg) were allocated in individual cages and analyzed in a 5x5 Latin square experimental design composed of five animals, five treatments and five evaluation periods of 14 days each. The contrast (protein supplement vs. mineral mixture) was not significant (p>0.05) for total dry matter intake, total organic matter intake, total ether extract intake and total carbohydrate intake variables. However, it was significant (p 0.05) either the water intake or ingestive behavior of sheep, with rumination and rest coinciding with dusk and dawn.

Foram avaliados os efeitos de níveis crescentes de suplemento proteico (50, 100, 150 e 200 gramas/animal dia-1) e do suplemento testemunha (mistura mineral) sobre o consumo, a digestibilidade dos nutrientes e o comportamento ingestivo de ovinos consumindo forragem tropical (Pennisetum purpureum Schum). Foram utilizados cinco borregos meio sangue Santa Inês x Sem Raça Definida, não castrados, com peso corporal inicial médio de 25,33 kg (± 4,40 kg), alocados em baias individuais e distribuídos em delineamento experimental quadrado latino 5x5, sendo cinco animais, cinco tratamentos e cinco períodos de avaliação de 14 dias cada. Observou-se que para as variáveis consumo de matéria seca total, consumo de matéria orgânica total, consumo de extrato etéreo total e consumo de carboidratos totais total, o contraste (suplemento proteico x mistura mineral) não foi significativo (p>0,05), contudo, este foi significativo (p0,05), portanto, mesmo no nível mais elevado de fornecimento de suplemento (200 g/dia) os animais não consumiram mais água pelo maior aporte proteico do mesmo. Concluiu-se que os níveis crescentes de suplementação proteica associados ao capim Elefante (Pennisetum purpureum Schum) de boa qualidade promovem incrementos nos parâmetros digestivos dos ovinos, contudo, a oferta de suplemento abaixo de 100 g/dia resulta em parâmetros semelhantes aos da mistura mineral. Adicionalmente, a suplementação proteica não afeta (P>0,05) a ingestão de água dos ovinos e o seu comportamento ingestivo, com ruminação e ócio coincidindo com o anoitecer e o amanhecer.

Raiva paralítica em suíno no Rio Grande do Sul / Paralytic rabies in swine at Rio Grande do Sul

A raiva é uma doença infecciosa, potencialmente zoonótica, de distribuição mundial que afeta mamíferos domésticos, silvestres e humanos. Na América do Sul a raiva paralítica ocorre na forma de surtos cíclicos e é transmitida por morcegos hematófagos, principalmente o Desmodus rotundus. É uma doença responsável por prejuízos econômicos na pecuária, além de apresentar importância para a saúde pública. O presente trabalho tem como objetivo relatar um caso de raiva suína diagnosticado no Laboratório Regional de Diagnóstico, da Faculdade de Veterinária, da Universidade Federal de Pelotas. O caso ocorreu em uma propriedade localizada no município do Capão do Leão em um suíno, fêmea, sem raça definida, de dois anos de idade, criada em regime semiextensivo. Segundo o proprietário o animal apresentou apatia, anorexia, paralisia progressiva e decúbito lateral. Devido a evolução do quadro clínico foi realizada a eutanásia. Na necropsia não foram observadas lesões significativas. No exame histopatológico do encéfalo observou-se meningoencefalite não supurativa, manguito perivascular de linfócitos e raros eosinófilos, além de satelitose e gliose. Fragmentos do encéfalo e medula foram submetidos ao exame de Imunofluorescência Direta e prova biológica, confirmando o diagnóstico de raiva.

Rabies is a potentially zoonotic infectious disease with worldwide distribution that affects domestic, wild and human mammals. In South America, paralytic rabies occurs in the form of cyclic outbreaks and is transmitted by hematophagous bats, mainly Desmodus rotundus. It is a disease responsible for economic losses in livestock, besides of presenting importance to public health. This paper aims to report a case of swine rabies diagnosed at the Laboratório Regional de Diagnostico, Faculdade de Veterinária, Universidade Federal de Pelotas. The case occurred in a property located in the county of Capão do Leão in a female pig, twoyear-old, undefined breed, raised in a semi-extensive regime. According to the owner, the animal presented apathy, anorexia, progressive paralysis and lateral decubitus. Due to the evolution of the clinical condition, euthanasia was performed. At necropsy no significant lesions were observed. Histopathological examination of the brain showed non-suppurative meningoencephalitis, perivascular cuff of lymphocytes and rare eosinophils, as well as satelitosis and gliosis. Brain and spinal cord fragments were submitted to Direct Immunofluorescence and biological tests, confirming the diagnosis of rabies.

Assessment of caseous lymphadenitis in goats in a slaughterhouse in the Brazilian semi-arid region and estimates of economic losses due to carcass condemnation / Avaliação da linfadenite caseosa em caprinos em um abatedouro na região do semiárido brasileiro e estimativas de perdas econômicas por condenação de carcaças

Caseous lymphadenitis (CLA) caused by the pathogenic bacterium, Corynebacterium pseudotuberculosis, results in economic loss in goat farming. Its prevalence in Brazilian herds varies from 5 to 50%, generating expenses with treatment, loss in production, carcass and organ condemnation, and reduced price of the hide. This study aimed to describe the distribution of lesions and quantify the loss associated with CLA in goat breeding due to condemnation in a slaughterhouse located in a semiarid region. The study was conducted at the municipal slaughterhouse of the city of Patos, State of Paraíba, Northeastern Brazil, where goats from this intermediate geographical region are slaughtered. In 2017, 3,662 animals were slaughtered, an average of 305 per month. During the study period, from March to August 2017, 304 goats of both sexes and different ages of undefined breed were assessed. In the ante-mortem examination, inspection and palpation of the superficial lymph nodes was done; in the post-mortem examination, organ and viscera were assessed. The caseous material collected was sent for microbiological analysis. Of the 304 individuals, 227 [74.67% (95% CI: 69.50-79.23)] did not have any lesions, while 77 [25.33% (95% CI: 20.77-30.50)] showed abscesses suggestive of CLA, which was confirmed in 65 goats [84.41% (95% CI: 76.30-92.50)]. Sex (P = 0.044) and age (P = 0.002) were associated with infection. While the sex of the animals affected carcass and viscera weights and carcass yield, their age affected live weight, carcass, organ, and viscera weights; conversely, the incidence of CLA did not affect these variables. The average price in Real (R$) of a kilogram (kg) of goat meat cuts and “offal” was used to calculate the economic loss. Considering the average carcass weight (11,485 kg), organ weight (1,085 kg), and viscera weight (2,013 kg), 4,433.232 kg of meat was produced, resulting in R$ 72,945.43. The condemnations resulted in the loss of 269.894 kg, which is equivalent to R$ 4,540.33. CLA is responsible for a negative impact of 6.09% on production. Implementing control measures for this disease is important to increase the financial return in goat farming.

Linfadenite Caseosa (LC) causada pela bactéria patogênica Corynebacterium pseudotuberculosis resulta em perda econômica na caprinocultura. No rebanho brasileiro sua prevalência varia de 5 a 50%, gerando gastos com tratamento, queda de produção, condenação de carcaça e órgãos, e desvalorização da pele. O objetivo deste trabalho foi quantificar a perda associada à LC na caprinocultura de corte por condenação em abatedouro do semiárido, bem como caracterizar a distribuição das lesões. O trabalho foi realizado no Abatedouro Municipal da cidade de Patos, Estado da Paraíba, Nordeste do Brasil, onde ocorre abate de caprinos provenientes desta região geográfica intermediária. No ano de 2017 foram abatidos 3.662 animais, uma média de 305 por mês. Durante o período de estudo, março a agosto do mesmo ano, avaliou-se 304 caprinos sem padrão racial definido, ambos os sexos e idades diversas. No exame ante mortem foram submetidos à inspeção e palpação de linfonodos superficiais; post mortem, órgãos e vísceras. O material caseoso coletado foi submetido à análise microbiológica para diagnóstico. Dos 304 indivíduos, 227 [74,67% (IC 95%: 69,50-79,23)] não apresentaram qualquer lesão, enquanto 77 [25,33% (IC 95%: 20,77-30,50)] evidenciaram abscessos sugestivos de LC, com confirmação em 65 [84,41% (IC 95%: 76,30-92,50)]. Constatou-se associação de sexo (P = 0,044) e idade (P = 0,002) à infecção. Foi verificado efeito do sexo dos animais nas variáveis peso de carcaça, peso de vísceras e rendimento de carcaça, bem como houve efeito da idade nas variáveis peso vivo, peso de carcaça, peso de órgãos e peso de vísceras; no entanto, não houve efeito da ocorrência de LC nessas variáveis. Para cálculo de perda econômica adotou-se o preço médio em Real (R$) do quilograma (kg) dos cortes de carne caprina, e “miúdos”. Considerando o peso médio de carcaça (11,485 kg), órgãos (1,085 kg) e vísceras (2,013 kg), houve produção de 4.433,232 kg, resultando em R$ 72.945,43. As condenações subtraíram 269,894 kg, equivalente a R$ 4.540,33. Atribui-se à LC um impacto negativo de 6,09% na produção. Implementar medidas de controle para essa doença é importante para que se amplie o retorno financeiro à atividade.

Its prevalence in Brazilian herds varies from 5 to 50%, generating expenses with treatment, loss in production, carcass and organ condemnation, and reduced price of the hide. This study aimed to describe the distribution of lesions and quantify the loss associated with CLA in goat breeding due to condemnation in a slaughterhouse located in a semiarid region. The study was conducted at the municipal slaughterhouse of the city of Patos, State of Paraíba, Northeastern Brazil, where goats from this intermediate geographical region are slaughtered. In 2017, 3,662 animals were slaughtered, an average of 305 per month. During the study period, from March to August 2017, 304 goats of both sexes and different ages of undefined breed were assessed. In the ante-mortem examination, inspection and palpation of the superficial lymph nodes was done; in the post-mortem examination, organ and viscera were assessed. The caseous material collected was sent for microbiological analysis. Of the 304 individuals, 227 [74.67% (95% CI: 69.50-79.23)] did not have any lesions, while 77 [25.33% (95% CI: 20.77-30.50)] showed abscesses suggestive of CLA, which was confirmed in 65 goats [84.41% (95% CI: 76.30-92.50)]. Sex (P = 0.044) and age (P = 0.002) were associated with infection. While the sex of the animals affected carcass and viscera weights and carcass yield, their age affected live weight, carcass, organ, and viscera weights; conversely, the incidence of CLA did not affect these variables. The average price in Real (R$) of a kilogram (kg) of goat meat cuts and “offal” was used to calculate the economic loss. Considering the average carcass weight (11,485 kg), organ weight (1,085 kg), and viscera weight (2,013 kg), 4,433.232 kg of meat was produced, resulting in R$ 72,945.43. The condemnations resulted in the loss of 269.894 kg, which is equivalent to R$ 4,540.33. CLA is responsible for a negative impact of 6.09% on production. Implementing control measures for this disease is important to increase the financial return in goat farming.(AU)

Linfadenite Caseosa (LC) causada pela bactéria patogênica Corynebacterium pseudotuberculosis resulta em perda econômica na caprinocultura. No rebanho brasileiro sua prevalência varia de 5 a 50%, gerando gastos com tratamento, queda de produção, condenação de carcaça e órgãos, e desvalorização da pele. O objetivo deste trabalho foi quantificar a perda associada à LC na caprinocultura de corte por condenação em abatedouro do semiárido, bem como caracterizar a distribuição das lesões. O trabalho foi realizado no Abatedouro Municipal da cidade de Patos, Estado da Paraíba, Nordeste do Brasil, onde ocorre abate de caprinos provenientes desta região geográfica intermediária. No ano de 2017 foram abatidos 3.662 animais, uma média de 305 por mês. Durante o período de estudo, março a agosto do mesmo ano, avaliou-se 304 caprinos sem padrão racial definido, ambos os sexos e idades diversas. No exame ante mortem foram submetidos à inspeção e palpação de linfonodos superficiais; post mortem, órgãos e vísceras. O material caseoso coletado foi submetido à análise microbiológica para diagnóstico. Dos 304 indivíduos, 227 [74,67% (IC 95%: 69,50-79,23)] não apresentaram qualquer lesão, enquanto 77 [25,33% (IC 95%: 20,77-30,50)] evidenciaram abscessos sugestivos de LC, com confirmação em 65 [84,41% (IC 95%: 76,30-92,50)]. Constatou-se associação de sexo (P = 0,044) e idade (P = 0,002) à infecção. Foi verificado efeito do sexo dos animais nas variáveis peso de carcaça, peso de vísceras e rendimento de carcaça, bem como houve efeito da idade nas variáveis peso vivo, peso de carcaça, peso de órgãos e peso de vísceras; no entanto, não houve efeito da ocorrência de LC nessas variáveis. Para cálculo de perda econômica adotou-se o preço médio em Real (R$) do quilograma (kg) dos cortes de carne caprina, e “miúdos”. Considerando o peso médio de carcaça (11,485 kg), órgãos (1,085 kg) e vísceras (2,013 kg), houve produção de 4.433,232 kg, resultando em R$ 72.945,43. As condenações subtraíram 269,894 kg, equivalente a R$ 4.540,33. Atribui-se à LC um impacto negativo de 6,09% na produção. Implementar medidas de controle para essa doença é importante para que se amplie o retorno financeiro à atividade.(AU)

Protein supplementation for sheep fed with tropical forage / Suplementação proteica para ovinos alimentados com forragem tropical

The effects of increasing levels of protein supplementation (50, 100, 150 and 200 animal per day) and mineral salt on feed intake, nutrient digestibility and ingestive behavior of sheep consuming tropical forage (Pennisetum purpureum Schum) were evaluated. Five non-castrated crossbred lambs (½ Santa Inês x ½ undefined breed) with average initial body weight of 35.0 kg (± 4.40 kg) were allocated in individual cages and analyzed in a 5x5 Latin square experimental design composed of five animals, five treatments and five evaluation periods of 14 days each. The contrast (protein supplement vs. mineral mixture) was not significant (p>0.05) for total dry matter intake, total organic matter intake, total ether extract intake and total carbohydrate intake variables. However, it was significant (p<0.05) for the variables forage dry matter intake, total crude protein intake, total mineral matter intake, total neutral detergent fiber intake and total non-fibrous carbohydrate intake, demonstrating possible replacement of forage by the supplement. Although the diet dry matter digestibility declined linearly (p <0.05), there was a significant linear increase effect of supplementation (P <0.05) on apparent digestibility of neutral detergent fiber, non-fibrous carbohydrates and consumption of digestible non-fibrous carbohydrates. This was due to higher participation of supplement in the diet ingested by supplemented sheep. The type of supplementation (protein or mineral mixture) did not affect the animals daily activities. Protein supplementation did not affect the water ingestion (P <0.05), demonstrating that even at the highest level of supplementation (200 g/day), animals were not induced to drink more water by the diet. We conclude that increasing levels of protein supplementation associated with good quality elephant grass resulted in increases in sheep digestive parameters, and supplementation below 100 g day-1 resulted in similar parameters to those of sheep receiving mineral mix (control). Additionally, protein supplementation did not affect (P> 0.05) either the water intake or ingestive behavior of sheep, with rumination and rest coinciding with dusk and dawn.(AU)

Foram avaliados os efeitos de níveis crescentes de suplemento proteico (50, 100, 150 e 200 gramas/animal dia-1) e do suplemento testemunha (mistura mineral) sobre o consumo, a digestibilidade dos nutrientes e o comportamento ingestivo de ovinos consumindo forragem tropical (Pennisetum purpureum Schum). Foram utilizados cinco borregos meio sangue Santa Inês x Sem Raça Definida, não castrados, com peso corporal inicial médio de 25,33 kg (± 4,40 kg), alocados em baias individuais e distribuídos em delineamento experimental quadrado latino 5x5, sendo cinco animais, cinco tratamentos e cinco períodos de avaliação de 14 dias cada. Observou-se que para as variáveis consumo de matéria seca total, consumo de matéria orgânica total, consumo de extrato etéreo total e consumo de carboidratos totais total, o contraste (suplemento proteico x mistura mineral) não foi significativo (p>0,05), contudo, este foi significativo (p<0,05) para as variáveis consumo de matéria seca de forragem, consumo de proteína bruta total, consumo de matéria mineral total, consumo de fibra em detergente neutro total e consumo de carboidratos não fibrosos total, demonstrando uma possível substituição da forrageira pelo suplemento. Apesar da digestibilidade da matéria seca da dieta ter sofrido redução linear (p<0,05), houve efeito significativo de caráter crescente e linear da suplementação (P<0,05) sobre a digestibilidade aparente da fibra em detergente neutro, digestibilidade aparente dos carboidratos não fibrosos e consumo de carboidratos não fibrosos digestíveis. Isto decorreu da maior participação do suplemento na dieta total ingerida pelos ovinos suplementados. O tipo de suplementação (proteica ou mistura mineral) não afetou a realização das atividades diárias dos ovinos enão houve variação no tempo gasto com consumo de água entre os tratamentos (P>0,05), portanto, mesmo no nível mais elevado de fornecimento de suplemento (200 g/dia) os animais não consumiram mais água pelo maior aporte proteico do mesmo. Concluiu-se que os níveis crescentes de suplementação proteica associados ao capim Elefante (Pennisetum purpureum Schum) de boa qualidade promovem incrementos nos parâmetros digestivos dos ovinos, contudo, a oferta de suplemento abaixo de 100 g/dia resulta em parâmetros semelhantes aos da mistura mineral. Adicionalmente, a suplementação proteica não afeta (P>0,05) a ingestão de água dos ovinos e o seu comportamento ingestivo, com ruminação e ócio coincidindo com o anoitecer e o amanhecer.(AU)

Doenças de felinos domésticos diagnosticadas no sul do Rio Grande do Sul: estudo de 40 anos / Domestic feline diseases diagnosed in southern Rio Grande do Sul: a 40-year study

O objetivo deste estudo foi identificar as principais doenças de felinos na região sul do Rio Grande do Sul. Foram revisados os protocolos de necropsia e das amostras biológicas de felinos encaminhados ao Laboratório Regional de Diagnóstico da Faculdade de Veterinária da Universidade Federal de Pelotas (LRD/UFPel), no período de 1978 a 2018. Nesse período foram recebidas 1633 amostras de felinos, sendo 363 (22%) entre os anos de 1978 e 1999 e 1270 (78%) entre os anos de 2000 e 2018. Com relação aos diagnósticos, 457 felinos (28%) apresentaram tumores benignos ou malignos, sendo os tegumentares e os mamários os mais frequentes. As doenças bacterianas, fúngicas, virais, parasitárias, sem agente definido e as intoxicações totalizaram 554 casos (33,9%), destacando-se a esporotricose, com 12,8% dos diagnósticos. Concluiu-se que, na região sul do RS, o encaminhamento de felinos para diagnóstico aumentou significativamente após o ano 2000, comprovando que a espécie passou a ter maior importância como animal de companhia. Concluiu-se, também, que as neoplasias têm papel relevante entre as doenças de felinos e que a esporotricose é uma das mais importantes zoonoses na região.(AU)

The goal of this paper was to identify the main disease affecting felines in the southern region of Rio Grande do Sul. The necropsy protocols and feline biological materials submitted to the Regional Diagnostic Laboratory of the Veterinary College of the Federal University of Pelotas (LRD / UFPel) were reviewed, from 1978 to 2018. During this period 1633 feline samples were received, 363 (22%) between 1978 and 1999 and 1270 (78%) between 2000 and 2018. 59% of felines did not present a defined breed. As for diagnoses, 457 felines (28%) presented benign or malignant tumors, the most common being the integumentary and mammary tumors. Bacterial, fungal, viral, parasitic or undefined agent infections and intoxications were observed in 554 cases (33.9%), especially sporotrichosis with 12.8 % of the diagnoses. It was concluded that in southern RS the referral of cats for diagnosis increased significantly after the year 2000, proving that they became more significant as companion animals. It was also concluded that neoplasia play a relevant role among feline diseases, and that sporotrichosis is one of the most important zoonoses in the region.(AU)

Malignant edema in horse by Clostridium perfringens type A

Background: Malignant edema is one of the terms used to designate severe necrotizing syndromes in soft tissues by Clostridium spp. which are potentially fatal in farm animals. These species are responsible for myonecrosis, belonging to the group of histotoxic clostridia, and may also culminate in toxemia with the worsening of the lesions. These clostridia and their spores require a gateway such as wounds on mucous membranes or skin, which may occur due to shear, tail cut, injuries during delivery, castration or injections by contaminated needles. This report aims to describe the clinicalpathological findings of a case of malignant edema caused by Clostridium perfringens type A in an equine. Case: A female equine, undefined breed, used as traction animal, had a history of abdominal pain. According to the requisitioning veterinary, the tutor reused needles for medication. On palpation, a compact mass was noticed in the pelvic f lexure, as well as edema on the region of head and neck with crackling areas. After surgical intervention for compactation correction, the animal did not show anesthetic recovery and was submited to euthanasia. Tissue samples were collected, f ixed in 10% buffered formalin solution, routinely processed for histopathology and stained with hematoxylin and eosin and Gram stain. Samples of serous-sanguineous edema fluid and fragments of the abdominal muscles and neck were collected. The samples were kept under refrigeration and sent for microbiological culture. Necropsy showed the subcutaneous region of the pectoral was markedly gelatinous and yellowish (edema) and subcutaneous emphysema characterized by accumulation of serous-sanguineous fluid and gas bubbles. In microscopy, we verified fibrous-haemorrhagic...

Hypoplasia of ribs associated with cleft palate, cleft lip, and unilateral renal agenesis in a neonate dog of undefined breed / Hipoplasia de costelas associada a fenda palatina, lábio leporino e agenesia renal unilateral em cão neonato sem raça definida

Congenital defects can cause changes in the normal function or morphology of organs, thus contributing to neonatal mortality. Malformations in dogs occur as a result of genetic factors or by the action of teratogenic agents during pregnancy. Genetic defects can be inherited from one or both parents. These defects are more common in purebred puppies or can even be the result of consanguinity. Teratogenic agents, such as toxins, drugs, infectious diseases, mechanical influences, and irradiation, may affect the litters during gestational development. Hypoplasia of ribs has been described in human newborns. It is a rare and lethal malformation of autosomal recessive inheritance that prevents thoracic expansion and reduces pulmonary compliance, causing respiratory failure. A pregnant bitch of undefined breed was submitted to caesarean section. At birth, a neonate exhibited respiratory distress, and the palpation of the thorax indicated absence of ribs. In addition, the newborn had cleft palate and cleft lip, which led to perform the euthanasia of the animal. Post-mortem examination indicated hypoplasia of ribs and unilateral renal agenesis. As in the canine neonate, hypoplasia of ribs in human newborns is also associated with other malformations, such as cleft lip, cleft palate, and urogenital defects. The present report describes the first case of hypoplasia of ribs associated with other malformations in a canine neonate, the cause being possibly related to a genetic hereditary factor.(AU)

Os defeitos congênitos podem causar alterações na função ou na morfologia normal de órgãos, contribuindo para a mortalidade neonatal canina. As malformações em cães podem ocorrer devido a fatores genéticos ou por ação de agentes teratogênicos durante a gestação. Os defeitos genéticos podem ser herdados de um ou ambos os pais, sendo mais comum em filhotes de raça pura, ou ainda ocorrerem por consaguinidade. Já os agentes teratogênicos como toxinas, fármacos, doenças infecciosas, influências mecânicas e irradiação, podem afetar a ninhada durante o desenvolvimento gestacional. A hipoplasia de costelas é relatada em recém-nascidos humanos, é uma malformação rara e letal de herança autossômica recessiva que impede a expansão torácica e reduz a complacência pulmonar, causando insuficiência respiratória. Uma cadela prenhe sem raça definida foi submetida à cesariana, ao nascimento um neonato apresentou sofrimento respiratório, à palpação do tórax presumiu-se ausência de costelas, o recém-nascido apresentava ainda fenda palatina e lábio leporino, e optou-se pela eutanásia do animal. No exame post-mortem foi diagnosticado hipoplasia de costelas e agenesia renal unilateral. Assim como encontrado no neonato canino, em recém-nascidos humanos a hipoplasia de costelas também está associada com outras malformações, como fenda labial e do palato e defeitos urogenitais. O presente relato descreve o primeiro caso de hipoplasia de costelas em neonato canino, associada com outras malformações, sendo a causa possivelmente relacionada a um fator genético hereditário.(AU)

Correção de fenda palatina secundária traumática em cão - relato de caso / Correction cleft palate secondary traumatic in dog - case report

A fenda palatina é a comunicação entre a cavidade oral e a nasal através de um orifício no palato. Tem diversas etiologias, podendo ser congênita, traumática, por deficiência mineral ou por fatores hormonais. O diagnóstico é realizado por meio de exame físico da cavidade oral, e a correção cirúrgica é o tratamento de escolha. Em animais adultos, pode ser corrigida com o auxílio de retalho mucoperiosteal, apresentando bons resultados. Já em filhotes, a correção cirúrgica é mais complicada, com prognóstico menos favorável. Este trabalho relata o caso de um canino, fêmea, sem raça definida, adulta, com histórico de fenda palatina secundária, de origem traumática, no palato mole por ingestão de osso. Para a correção cirúrgica, primeiramente foi utilizada membrana biológica de pericárdio bovino, mas não se obteve êxito. O segundo procedimento foi realizado com retalho mucoperiosteal simples autólogo e, dois meses após o procedimento, já havia cicatrização completa. A técnica de retalho mucoperiosteal simples autólogo se mostrou eficaz no tratamento da fenda palatina, aliada aos cuidados adequados no pós-operatório.(AU)

The cleft palate is the communication between the oral and nasal cavity through an aperture in the palate, it's causes include an infinitude of factors: congenital, traumatic, mineral deficiency or hormonal. Examination of the oral cavity determines if the diagnosis and treatment is surgical. Correction in adult animals is performed with mucoperiosteal flap showing good results. However, surgical correction in puppies is more complicated with less favorable prognosis. This current work reports a case of an adult, female dog of undefined breed, with a history of secondary clef palate of traumatic origin in the soft palate due to bone ingestion. For correction, a biological membrane of bovine pericardium was used, but it was not successful, requiring a second surgical procedure performed with autologous simple mucoperiosteal flap. The last technique combined with adequate postoperative care was effective.(AU)

Tracheal avulsion in a cat / Avulsão traqueal em um gato

Tracheal avulsion is a condition seen in small animals and occurs as a result of a traumatic incident to the cervical and/or thoracic regions. The aim of this study is to report a case of tracheal avulsion in a cat using imaging examinations for diagnostic investigation. In this report, we examined an eight-month-old male, cat of undefined breed, diagnosed with tracheal avulsion using complementary imaging tests. This diagnosis was confirmed with post-mortem examination. Radiographic examination of the patients thorax and a tracheoscopy were performed. These examinations revealed complete discontinuity of the tracheal circumference, the presence of focal and circumscribed dilation of the tracheal lumen and stenosis. The patient quickly died without clinical and surgical intervention. Macroscopic analysis revealed a tracheal diverticulum confirming the findings of the imaging tests. The use of radiographic examinations in conjunction with tracheoscopy was effective at diagnosing this condition.(AU)

A avulsão traqueal é uma condição identificada em pequenos animais e ocorre como resultado de um incidente traumático na região cervical ou torácica. O objetivo deste trabalho consiste em relatar um caso de avulsão traqueal em um felino doméstico submetido a exames de imagem para investigação diagnóstica. Um felino, macho, sem raça definida, de oito meses de idade, foi diagnosticado com avulsão traqueal por meio de exames complementares de imagem e com confirmação diagnóstica por exames post mortem. O paciente foi submetido a exames radiográficos do tórax e traqueoscopia. Os achados dos exames de imagem revelaram completa descontinuidade da circunferência traqueal, presença de dilatação focal e circunscrita do lúmen traqueal e estenose. O paciente morreu e não houve tempo hábil para intervenção cirúrgica. Na análise macroscópica identificou-se um divertículo traqueal, confirmando assim, os achados dos exames de imagem. A utilização dos exames radiográficos em conjunto com a traqueoscopia foi efetiva no diagnóstico dessa condição.(AU)
