Purpose: To compare laparoscopic gynecological surgery training between a developed country's reference center (host center) and a public reference service in a developing country (home center), and use the technicity index (TI) to compare outcomes and to determine the impact of laparoscopic gynecological surgery fellowship training on the home center's TI. Methods: The impact of training on the home center was assessed by comparing surgical performance before and after training. TI was assessed in 2017 in the host center, and before and after training in the home center. Epidemiological and clinical data, and information on reason for surgery, preoperative images, estimated intraoperative bleeding, operative time, surgical specimen weight, hospital stay length, complication and reintervention rates were collected from both institutions. Home center pre-training data were retrospectively collected between 2010 and 2013, while post-training data were prospectively collected between 2015 and 2017. A two-tail Z-score was used for TI comparison. Results: The analysis included 366 hysterectomies performed at the host center in 2017, and 663 hysterectomies performed at the home center between 2015 and 2017. TI in the host center was 82.5%, while in the home center it was 6% before training and 22% after training. There were no statistical differences in length of hospital stay, preoperative uterine volume, surgical specimen weight and complication rate between centers. However, significantly shorter mean operative time and lower blood loss during surgery were observed in the host center. Conclusions: High-quality laparoscopic training in a world-renowned specialized center allowed standardizing laparoscopic hysterectomy procedures and helped to significantly improve TI in the recipient's center with comparable surgical outcomes.

A male adult ocelot (Leopardus pardalis) kept under human care developed anuria, which progressed to death. Grossly, the urinary bladder was markedly dilated and filled with red discolored urine containing blood clots. In addition, the animal had a hepatoid cell adenoma adjacent to the urethra, which likely caused partial urethral occlusion. Microscopically, there was a predominantly neutrophilic, fibrinous and hemorrhagic urethritis, cystitis, and pyelonephritis with intralesional gram-positive cocci. Microbiologic culture followed by MALDI-TOF MS analysis resulted in the identification of isolates from the urine and urethra as Staphylococcus felis.(AU)

Several agents can cause hemoparasitic diseases in dogs, and blood-sucking arthropods transmit these diseases. These agents can cause several clinical manifestations and, in some cases, can kill the host. Because these agents are essential in animal health, this study aims to detect the frequency of Ehrlichia canis, Rickettsia rickettsii, Anaplasma platys, and Rangelia vitalii by real-time PCR and Babesia vogeli in dogs in the southern region of the city of São Paulo, São Paulo. Of the 98 dog samples, 18 (18.4%) tested positive with real-time polymerase chain reaction for at least one studied agent. Of these 18 samples, 17 tested positive for a single agent (11.2% for B. canis vogeli, 1.02% for R. vitalii, and 5.1% for E. canis), and one showed co-infection with B. canis vogeli and R. vitalii. The results demonstrate the presence of hemoparasites in the studied animals, which can influence the quality and life expectancy of these animals. The Rangeliadetection warns small animal clinicians to include it as a differential diagnosis for hemoparasitosis.(AU)
As hemoparasitoses em cães podem ser causadas por diversos agentes, sendo essas doenças transmitidas por artrópodes hematófagos. Esses agentes podem causar diversas manifestações clínicas e, em alguns casos, podem matar o hospedeiro. Este estudo teve como objetivo detectar por PCR em tempo real a frequência de Ehrlichia canis, Rickettsia rickettsii, Anaplasma platys, Rangelia vitalii e Babesia canis vogeli em amostras de cães da zona sul da cidade de São Paulo, Brasil. Das 98 amostras de cães, 18 (18,4%) testaram positivo com reação em cadeia da polimerase em tempo real para pelo menos um agente estudado. Destas 18 amostras, 17 testaram positivo para um único agente (11,2% para B. canis vogeli, 1,02% para R. vitalii e 5,1% para E. canis), e uma apresentou coinfecção com B. canis vogeli e R. vitalii. Os resultados demonstram a presença de hemoparasitas nos animais estudados, o que pode influenciar a qualidade e a expectativa de vida desses animais. Além disso, é o primeiro relato da detecção de R. vitalli na zona sul de São Paulo e serve de alerta para os clínicos de pequenos animais incluírem esse agente como diagnóstico diferencial para as hemoparasitoses.(AU)

Background: Domestic cats have been implicated as accidental hosts of Leishmania sp. However, in recent years, the recurrent description of new cases in endemic and nonendemic areas draw attention to the potential epidemiological role of cats as reservoir hosts. Although dogs are considered urban reservoirs, cats could act as a secondary natural reservoirs in these areas. Thus, feline leishmaniasis has become an emerging disease in several countries worldwide. Case presentation: This study aimed to describe the first case of feline leishmaniasis in a stray animal that presented lesions compatible with the disease in Belém, Pará, Brazil, an important urban area in eastern Amazon. Serological tests for Leishmania infantum (ELISA and IFA) were nonreactive, whereas histopathological examination indicated infectious dermatitis caused by Leishmania spp. or Toxoplasma gondii. Cytopathological study of lesion aspirate confirmed the presence of Leishmania sp. amastigotes within macrophages. Finally, molecular analyses revealed that the feline infection was caused by Leishmania (Leishmania) infantum chagasi. Conclusion: To the best of the authors' knowledge, this study reports the first case of natural infection by Leishmania (Leishmania) infantum chagasi in a feline from eastern Amazon. These findings suggest domestic cats as potential secondary reservoir hosts of Leishmania spp. in Belém, which reinforces the importance of further epidemiological investigation of feline leishmaniasis, especially in urban areas with human cases.(AU)

The synanthropization of wild animals puts public health at risk by promoting the circulation of zoonotic agents, found naturally in the wild, in the anthropic environment. The objective of this work was to carry out screening by molecular detection of pathogens of the Anaplasmatacea family in Didelphis albiventris, a specie characterized as having a synanthropic habit. Opossums that were dead (n = 25) after being road-killed were collected in the North of Paraná state, southern Brazil during the 2016 and 2018 years, through active search. A questionnaire was filled out with information about the animal and collected place. Biological samples of spleen and liver were collected. The genetic material extracted from the spleen and liver was submitted to molecular diagnosis through PCR for amplification of dsb of Ehrlichia and 16S genes for the other agents of the Anaplasmataceae family. One animal was positive for the genus Ehrlichia in semi-nested PCR for amplification of the 349 bp fragment of the dsb gene in extracted from the liver samples. In PCR for the 16S target no animal was positive. These are preliminary results that reinforce the circulation of Ehrlichia in opossums. To improve the knowledge of these agents in opossums more studies are necessary.(AU)
A sinantropização de animais silvestres coloca em risco a saúde pública por propiciar a circulação de agentes zoonóticos, encontrados naturalmente em ambiente silvestre, no ambiente antrópico. O trabalho teve como objetivo realizar a triagem por detecção molecular de patógenos da família Anaplasmataceae em Didelphis albiventris, espécie caracterizada como de hábito sinantrópico. Gambás mortos (n=25) por atropelamento durante os anos de 2016 e 2018 foram coletados na região norte do Paraná, sul do Brasil, por meio de busca ativa. Realizou-se o preenchimento de formulário com informações sobre a espécie do animal e o local do atropelamento. Foi realizada a necrópsia e coleta de amostras biológicas, de baço e fígado. O material genético extraído de baço e fígado foi submetido a diagnóstico molecular, por meio de PCR, para amplificação dos genes dsb de Ehrlichia sp. e 16S para os demais agentes da família Anaplasmataceae. Um animal foi positivo para o gênero Ehrlichia em semi-nested PCR para a amplificação do fragmento de 349 pb do gene dsb, extraído de fígado. Na PCR para detecção do gene 16S nenhum dos animais foi positivo. Esses resultados preliminares reforçam a circulação de Ehrlichias em gambás. Para melhorar o conhecimento desses agentes em gambás mais estudos são necessários.(AU)

A Esporotricose é uma micose subcutânea de caráter zoonótico causada pelo fungo Sporothrix schenckii que habita o solo, palhas, vegetais e também madeiras, podendo ser transmitido por meio de materiais contaminados, como farpas ou espinhos. Contudo os animais infectados e em especial os gatos, também transmitem a doença, por meio de arranhões, mordidas e contato direto com pele lesionada. Nos mamíferos, o quadro clínico apresenta-se na forma crônica ou aguda com o surgimento de lesões cutâneas. A doença é considerada um problema de saúde pública, pois afeta a população de áreas endêmicas. O presente trabalho foi delineado para analisar a manifestação da doença em gatos domésticos, revisando sinais clínicos, diagnóstico, prevenção, tratamento e também faz um alerta para a sua importância em saúde pública.(AU)
Sporotrichosis is a zoonotic subcutaneous mycosis caused by the fungus Sporothrix schenckii that inhabits the soil, straw, vegetables and also wood, and can be transmitted through contaminated materials, such as splinters or thorns. However, infected animals, and especially cats, also transmit the disease through scratches, bites and direct contact with injured skin. In mammals, the clinical picture is chronic or acute with the appearance of skin lesions. The disease is considered a public health problem, as it affects the population of endemic areas. The present work was designed to analyze the manifestation of the disease in domestic cats, reviewing clinical signs, diagnosis, prevention, treatment and also makes an alert for its importance in public health. Educational measures are needed to make the population aware of the effects of waste on One Health.(AU)

Neotropical primates are represented by more than 200 species and subspecies distributed in five families. Considering that some of these species are considered endangered, disease investigation in these populations is critical for conservation strategies. Therefore, an increasing number of studies and publications on this topic became available in the past few years. This review deals with infectious diseases of neotropical primates, with focus on free-ranging animals, including those caused by bacterial, viral, protozoal, metazoan, or mycotic infectious organisms, with particular emphasis on gross and microscopic lesions associated with these diseases. In addition, a few relevant unpublished cases of infection by Staphylococcus spp., Streptococcus spp., E. coli and Pseudomonas spp. were included in this review.(AU)

Background: Dermatophytes, fungi of universal distribution, invade semi or fully keratinized structures, such as skin, fur/ hair and nails. The various species of dermatophytes are classified into three genera anamorphic: Microsporum, Trichophyton and Epidermophyton. The genus Epidermophyton includes only E. floccosum, that rarely affects animals. The main species responsible for the disease in dogs and cats are Microsporum canis, M. gypseum and Trichophyton mentagrophytes, which were characterized through conventional mycological methodology (microscopic examination with KOH and culture). Molecular methodologies, such as real-time PCR, can contribute to a rapid laboratory diagnosis, helping clinicians to initiate an early antifungal treatment. This case report describes a case of canine dermatophytosis due to Trichophyton mentagrophytes detected from a clinical sample by SYBR-Green real-time PCR. Case: A 8-year-old dog, rescued from the street, was referred to a private veterinary clinic in the city of Canoas, RS, Brazil, presenting generalized lymphadenomegaly, crusted lesions all over the body, generalized alopecia, signs of excoriation and epistaxis. Initially, were administered prednisone [1 mg/kg every 48 h, BID] and cephalexin [30 mg/kg, BID]. Weekly baths with benzoyl peroxide were also given. The therapy was not clinically successful. Wood's Lamp Test was negative. As a differential diagnosis, PCR for detection of Leishmania was negative. Complete blood count and serum biochemical assay were also performed. For mycological diagnosis, hair specimen was clarified and examined microscopically using 10% potassium hydroxide (KOH) for the visualization of chains of arthroconidia (ectothrix invasion of hair). The infected hair was plated onto MycoselTM Agar, incubated at 28°C for 15 days. Microscopy of hyphae/ conidia and macroscopic colony characteristics (colors and texture) were conducted for the differentiation of the species within the genus Microsporum and Trichophyton. In addition, real-time PCR was applied for direct analysis of the fungal DNA obtained from the hair sample. Microscopic examination was negative. The dermatophyte present in the hair sample was confirmed as Trichophyton mentagrophytes by culture and qPCR (melting-point analysis). The patient was treated with systemic itraconazole [10 mg/ kg SID - 90 days]. Twice-weekly application of 2.5 % miconazole and 2% chlorhexidine shampoo until complete cure. Discussion: Dermatophytosis is often listed as self-limiting infection; however, animal dermatophytosis can spread between pets, as well as a zoonotic transmission to humans. The literature on dermatophytosis indicates that Microsporum canis is the predominant etiological agent, followed by M. gypseum. Trichophyon mentagrophytes that appear in a lower percentage of isolation. The culture of hair, even with specific medium containing chloramphenicol and cyclohexamide, may present contaminating fungi, not related to dermatophytosis, which can inhibit or override the growth of dermatophytes. The use of real-time PCR provided a faster and specific diagnosis of dermatophytosis when compared to the conventional mycological methodology for detection and identification of T. mentagrophytes, which takes around 10 to 15 days for culture. It is possible to use this technique as an alternative diagnosis for dermatophytes associated to clinical hair samples of dogs.

Tuberculosis is a communicable disease with high morbidity and mortality rates in developing countries. The study's primary objective is to compare conventional methods such as acid-fast bacillus (AFB) culture and microscopy with rapid diagnostic methods. The secondary objective is to compare histopathological and microbiological findings in suspected patients with tubercular lymphadenitis. A total of 111 samples (August 2018 to September 2019) of lymph nodes were processed for AFB microscopy, AFB cultures, drug-susceptibility testing (DST), histopathology, and Xpert Mycobacterium Tuberculosis (MTB)/resistance to Rifampin (RIF) assays. Out of 111 lymph node samples, 6 (5.4%) were positive for AFB smear microscopy, 84 (75.6%) were positive for AFB culture, 80 (70.7%) were positive on Gene Xpert, and 102 (91.8%) were indicative of tuberculosis for histopathology studies. Mycobacteria growth indicator tube (MGIT) culture positivity was 84 (75.6%) higher than solid Lowenstein-Jensen (LJ) culture 74 (66.6%). Positive cultures underwent phenotypic DST. Two cases were Multidrug-resistant (MDR) on DST, while three cases were Rifampicin resistant on Gene Xpert. The sensitivity of Genexpert was (62%) against the conventional AFB culture method. The poor performance of conventional lymphadenitis diagnostic methods requires early and accurate diagnostic methodology. Xpert MTB/RIF test can help in the treatment of multidrug-resistant TB cases. Nonetheless, rapid and conventional methods should be used for complete isolation of Mycobacterium tuberculosis.
A tuberculose é uma doença transmissível com altas taxas de morbimortalidade nos países em desenvolvimento. O objetivo principal do estudo é comparar métodos convencionais, como cultura de bacilo álcool-ácido resistente (BAAR) e microscopia, com métodos de diagnóstico rápido. O objetivo secundário é comparar os achados histopatológicos e microbiológicos em pacientes com suspeita de linfadenite tubercular. Um total de 111 amostras (agosto de 2018 a setembro de 2019) de gânglios linfáticos foi processado para microscopia de AFB, culturas de AFB, teste de susceptibilidade a drogas (DST), histopatologia e Xpert Mycobacterium tuberculosis (MTB)/ensaios de resistência à rifampicina (RIF). Das 111 amostras de linfonodos, 6 (5,4%) foram positivas para baciloscopia de AFB, 84 (75,6%) foram positivas para cultura de AFB, 80 (70,7%) foram positivas para o GeneXpert e 102 (91,8%) foram indicativas de tuberculose para estudos histopatológicos. A positividade da cultura do tubo indicador de crescimento de micobactérias (MGIT) foi 84 (75,6%), maior que a cultura sólida de Lowenstein-Jensen (LJ), 74 (66,6%). As culturas positivas foram submetidas a DST fenotípico. Dois casos eram multirresistentes (MDR) ao DST, enquanto três casos eram resistentes à rifampicina no GeneXpert. A sensibilidade do GeneXpert foi 62% contra o método convencional de cultura AFB. O fraco desempenho dos métodos convencionais de diagnóstico de linfadenite requer metodologia de diagnóstico precoce e precisa. O teste Xpert MTB/RIF pode ajudar no tratamento de casos de tuberculose multirresistente. No entanto, métodos rápidos e convencionais devem ser usados para o isolamento completo do Mycobacterium tuberculosis.

Abstract Background: Twenty-minute whole blood clotting test (20WBCT) and Modified Lee and White (MLW) method are the most routinely employed bedside tests for detecting coagulopathic snake envenomation. Our study compared the diagnostic utility of MLW and 20WBCT for snakebite victims at a tertiary care hospital in Central Kerala, South India. Methods: This single-center study recruited 267 patients admitted with snake bites. 20WBCT and MLW were performed simultaneously at admission along with the measurement of Prothrombin Time (PT). The diagnostic utility of 20WBCT and MLW was determined by comparing the sensitivity (Sn), specificity (Sp), positive and negative predictive values, likelihood ratios, and accuracy at admission with an INR value > 1.4. Results: Out of 267 patients, 20 (7.5%) patients had VICC. Amongst those who had venom-induced consumption coagulopathy (VICC), MLW was prolonged for 17 patients, (Sn 85% 95% confidence interval [CI]: 61.1-96.0) whereas 20WBCT was abnormal for 11 patients (Sn 55%, 95% CI: 32.04-76.17). MLW and 20WBCT were falsely positive for the same patient (Sp 99.6%, 95% CI: 97.4-99.9%). Conclusion: MLW is more sensitive than 20WBCT to detect coagulopathy at the bedside amongst snakebite victims. However, further studies are necessary for standardizing bedside coagulation tests in snakebite cases.

This study aimed to investigate the epidemiological and pathological findings of type 1 and 2 abomasal ulcers in cattle with different primary comorbidities. A total of 201 animals; 40/201 (20%) were young cattle under the age of two years and 161/201 (80%) were adult cattle over the age of two years, which were hospitalized for clinical care 152/201 (75,62%), 19/201 (9,45%) obstetric care, 17/201 (8,46%) surgical care and 13/201 (6,47%) for anatomopathological diagnosis, being euthanized or had natural death. The diagnosis of ulcers was based on the result of the post-mortem examination (macroscopic and histopathological analysis). Histopathological examination was performed on 201 fragments of ulcers and classified as type 1 or type 2. Of these, 193/201 (96.01%) corresponded to type 1 ulcers, of which 12/193 (5.97%) corresponded to subtype 1a lesions, 101/193 (50.25%) to subtype 1b, 77/ 193 (38.31%) to subtype 1c, 03/193 (1.49%) to subtype 1d, while 08/201 (3.98%) were type 2 ulcers. The ulcers were characterized by a focal, focally extensive, multifocal or diffuse inflammatory process, mainly by mononuclear cells. Abomasitis associated with ulcerated mucosa was found in 160/201 (79.60%). In 26/201 (12.93%) the abomasitis had diffuse foci of multifocal lymphocytic proliferation by atypical lymphocytes. Digestive and reproductive comorbidities were seen more frequently in cattle with type 1 or type 2 ulcers. The Subtype 1b focal ulcers and subtype 1a and 1b multifocal ulcers were more prevalent. In addition to the presence of comorbidities, most cases occur in the dry period, associated with feeding with higher amounts of concentrates and silages.(AU)
Objetivou-se estudar os achados epidemiológico e anatomopatológico de úlceras do abomaso tipo 1 e 2 em bovinos com diferentes comorbidades primárias. Um total de 201 animais; 40/201 (20%) eram bovinos jovens com idade inferior a dois anos e 161/201 (80%) eram bovinos adultos com idade superior a dois anos, os quais foram internados para atendimento clínico 152/201 (75,62%), 19/201 (9,45%) obstétrico, 17/201 (8,46%) para atendimento clínico-cirúrgico e 13/201 (6,47%) para diagnóstico anatomopatológico, sendo eutanasiados ou tiveram morte natural. O diagnóstico das úlceras foi baseado no exame post-mortem (análise macroscópica e histopatológica). O exame histopatológico foi realizado em 201 fragmentos de úlceras e classificado como tipo 1 ou do tipo 2. Destes, 193/201 (96,01%) corresponderam a úlceras tipo 1, das quais, 12/193 (5,97%) corresponderam a lesões subtipo 1a, 101/193 (50,25%) a subtipo 1b, 77/193 (38,31%) a subtipo 1c, 03/193 (1,49%) ao subtipo 1d, enquanto 08/201 (3,98%) foram úlceras tipo 2. As úlceras foram caracterizadas por processo inflamatório focal, focalmente extenso, multifocais ou difusos, principalmente por células mononucleares. Abomasite associada à mucosa ulcerada foi encontrada em 160/201 (79,60%). Em 26/201 (12,93%) a abomasite apresentava focos difusos de proliferação linfocítica multifocal por linfócitos atípicos. As comorbidades digestivas e reprodutivas foram observadas com maior frequência em bovinos com úlceras tipo 1 ou tipo 2. As úlceras focais subtipo 1b e úlceras multifocais subtipo 1a e 1b foram mais prevalentes. Além da presença de comorbidades, a maioria dos casos ocorrerem no período seco, associados à alimentação com maiores aportes de concentrados e silagens.(AU)

Background: Peritoneopericardial diaphragmatic hernia is a rare pathogenesis of congenital origin, which occurs due to a failure in the communication between the diaphragm and the pericardium during embryogenesis. Symptoms may be non-existent or non-specific, depending on the herniated organ involved and, in most cases, the diagnosis is incidental. Regarding the most indicated treatment, there are still divergences in the literature concerning the indication of conservative or surgical treatment. This study reports the case of a feline peritoneopericardial hernia, for which surgical correction was the treatment of choice. Case: A 3-month-old female kitten, no defined racial pattern, was referred to the Veterinary Hospital of the Federal Rural University of Pernambuco for treatment of a peritoneopericardial diaphragmatic hernia. This condition was diagnosed through radiographic examination after the patient having been submitted to pediatric castration and presented anesthetic complications in the transsurgery. Blood count, biochemical profile and Doppler echocardiogram were performed, which showed no significant changes. To obtain a better study and surgical planning, computed tomography was performed to observe the heart located cranially in the pericardial cavity. Caudally to the heart, hepatic parenchyma located in the pericardial cavity was observed; and hepatic vessels presenting slightly enlarged dimensions. These tomographic findings suggested peritoneopericardial diaphragmatic hernia; being the liver present in the pericardial cavity and signs of congestion in the hepatic parenchyma. Due to the likelihood of future worsening of the hernia, surgical correction was performed, with an abdominal midline incision in the preumbilical region to reposition the liver to its normal anatomy, followed by diaphragm reconstitution through a herniorrhaphy. After the surgical procedure, the patient was referred for observation in internment and, after 15 days, the skin sutures were removed. Complete correction of the hernial defect was observed on radiography performed 30 days after the surgical procedure. However, the examination showed the presence of deviation/ deformity in the topography of the sternum and costal cartilages, with slight cardiac displacement to the right hemithorax, suggesting the presence of pectus excavatum. Discussion: Peritoneopericardial diaphragmatic hernia is considered rare and, despite being one of the most common causes of congenital pericardial anomaly in felines, it has a low prevalence ranging from 0.06% to 1.45%. They are usually diagnosed from two years of age, with prevalence for older animals. However, due to having presented anesthetic changes, the patient of this case report could be diagnosed early. Among the most common organs that migrate to the thoracic cavity, the liver is the most commonly observed, which is also the hernia content of the present report. Peritoneopericardial hernia is often diagnosed through radiography and ultrasound, and these imaging tests proved to be sufficient for the diagnosis in this report. However, computed tomography was important for providing a better study of case and for the adoption of median celiotomy as a treatment. Associations with other malformations are described in the literature, with pectus excavatum being the most common and also observed in this report. Peritoneopericardial diaphragmatic hernia is a rare anomaly, rarely reported in the literature and with divergences regarding its treatment. The adoption of early surgical treatment performed in this report showed satisfactory evolution and the possibility of a favorable prognosis.

Biliary neoplasms are uncommon in cats and affect older animals. A 12-year-old female crossbreed cat showed prostration, lethargy, apathy, and severe jaundice. Ultrasonography showed distention of the gallbladder associated with severe obstruction of the bile ducts with thickening of the biliary wall, forming amorphous masses of irregular contour and heterogeneous appearance directed to the lumen measuring up to 2 cm. Necropsy showed a gallbladder with a yellowish and soft nodule measuring 3 × 3 cm, compressing the extrahepatic bile duct, occluding the passage of bile. There were also firm, yellowish multifocal to coalescing nodules in the liver, ranging from 0.5 to 1 cm, affecting 10% of the organ, in addition to lungs with firm, yellowish multifocal nodules ranging from 0.2 to 0.5 cm, affecting 20% of the organ. Histologically, gallbladder and bile ducts had malignant epithelial neoplastic proliferation, which was organized into multiple papillary and ductal projections, separated by moderate fibrovascular stroma compatible with gallbladder adenocarcinoma. The liver and lungs also contained neoplastic structures with a ductal appearance and papilliform projections identical to those observed in the gallbladder. The immunohistochemical examination (IHC) showed intense positive staining of epithelial neoplastic cells for pan-cytokeratin (AE1/AE3) and no staining for vimentin (Clone V9). The diagnosis of gallbladder adenocarcinoma with metastasis in the liver and lungs was established based on the clinical, macroscopic, histopathological, and immunohistochemical findings.(AU)

The frequency of gastrointestinal parasites with an emphasis on Strongylus vulgaris was investigated among the Brazilian Pony breed kept on farms in the municipality of Teresópolis, state of Rio de Janeiro. Fecal samples were collected in three stud farms: A (n= 22 animals), B (n= 3), and C (n= 2). Fecal samples were subjected to the quantitative Mini-FLOTAC technique, using three different solutions, and to qualitative techniques. The parasite prevalence was found to be 81.4%. Eggs from strongylids were identified in 74% of the ponies. Eggs of Parascaris spp. were detected in 22.7% of the animals, which were all females of farm A. At this locality, mares were kept with their foals in fenced paddocks all the time. The NaCl solution of d = 1.200 g/ml was generally the one that presented the highest frequency of diagnosis of nematode eggs and the highest mean of fecal eggs per gram. The fecal samples were also subjected to the polymerase chain reaction for amplification of DNA from the ITS2 region for Strongylus vulgaris. Twelve samples presented nucleotide sequences for S. vulgaris. In the end, this study revealed the high frequency (96.3%) of S. vulgaris among ponies on farms in Teresópolis, Rio de Janeiro, Brazil.(AU)
A frequência de parasitos gastrointestinais, com ênfase na pesquisa de Strongylus vulgaris, foi investigada entre os Pôneis Brasileiros criados em haras na cidade de Teresópolis, no estado do Rio de Janeiro. Amostras fecais foram coletadas em três haras: A (n=22 animais), B (n=3) e C (n=2). Amostras fecais foram submetidas à técnica quantitativa de Mini-FLOTAC utilizando três diferentes soluções e técnicas qualitativas. A prevalência de parasitos foi de 81,4%. Ovos de estrôngilos foram identificados em 74% dos pôneis. Ovos de Parascaris spp. foram detectados em 22,7% dos animais, sendo todos fêmeas do haras A. Nesta propriedade, as éguas eram mantidas com os pôneis em piquetes cercados durante todo o tempo. A solução de NaCl, com densidade de 1.200 g/ml, foi a que apresentou a maior frequência diagnóstica de ovos de nematoides e a maior contagem de ovos por grama de fezes. As amostras também foram submetidas à reação de polimerase em cadeia para amplificar DNA da região ITS2 de Strongylus vulgaris. Doze amostras fecais apresentaram sequências nucleotídicas de S. vulgaris. Ao final, este estudo demonstrou a alta frequência (96.3%) de S. vulgaris em pôneis mantidos em haras na cidade de Teresópolis, Rio de Janeiro, Brazil.(AU)

The objective was to study the composition of sand fly species, the seasonal activity of the dominant species and correlation with average rainfall, sex association of the dominant species with domicile habitats and analyze different landscape scenarios for the two study sites in the municipalities of Itapevi and Mogi of the Crosses. Sandflies were captured with CDC(s) traps installed in three households at each study site for a period of 24 hours, biweekly for two years. A total of 2970 specimens were collected. The dominant species were P.fischeri and M.migonei. A statistically significant difference was registered between males and females of the two species in relation to the intra and peridomicile. The seasonal activity of both species showed a weak significant positive correlation with rainfall. The species P.fischeri and M.migonei may be potential vectors of CVL in the studied sites.(AU)
O objetivo foi estudar a composição das espécies de flebotomíneos, a atividade sazonal das espécies dominantes e a correlação com médias pluviométricas, associação de sexo das espécies dominantes com habitats domiciliares. Também analisar diferentes cenários da paisagem para os dois sítios de estudo nos municípios de Itapevi e Mogi das Cruzes. Os flebotomíneos foram capturados com armadilhas CDC(s) instaladas em três domicílios de cada sítio de estudo por um período de 24 horas, quinzenalmente por dois anos. Um total de 2.970 espécimes foram coletados. As espécies dominantes foram P.fischeri e M.migonei. Foi registrada diferença estatística significante entre machos e fêmeas das duas espécies em relação ao intra e peridomicílio. A atividade sazonal das duas espécies apresentou fraca correlação positiva significante com a chuva. As espécies P.fischeri e M.migonei podem ser potenciais vetores de LVC nos locais de estudo.(AU)

In 2017, the Brazilian State of Amapá registered the first occurrence of visceral leishmaniosis (VL) in 17 dogs in the outskirts of the capital, Macapá. Given the lack of knowledge on phlebotomines in that area, this study aimed to survey the fauna of these Diptera. Sampling was performed using CDC light traps placed at ten sampling sites. The specimens captured were Evandromyia walkeri (n=237), Nyssomyia antunesi (n=65) and Bichromomyia flaviscutellata (n=6). The phlebotomine species composition resulted in low species diversity, and none of the main vectors of the etiological agent of VL were identified in the study area.(AU)
Em 2017, o estado do Amapá registrou a primeira ocorrência de Leishmaniose Visceral (LV) em 17 cães, na periferia da capital, Macapá. Tendo em vista a falta de conhecimento sobre flebotomíneos nessa área, este trabalho teve como objetivo fazer um levantamento da fauna desses dípteros. A amostragem foi realizada usando-se armadilhas de luz CDC, colocadas em dez locais de amostragem. Os espécimes capturados foram Evandromyia walkeri (n=237), Nyssomyia antunesi (n=65) e Bichromomyia flaviscutellata (n=6). A composição de espécies de flebotomíneos resultou em baixa diversidade de espécies, e nenhum dos principais vetores do agente da LV foi identificado na área de estudo.(AU)

As neoplasias mamárias representam a terceira neoplasia mais comum em gatas, enquanto nos machos a incidência é rara. Esse trabalho relata o caso de um gato macho, não castrado, atendido no Hospital Veterinário da Universidade Estadual do Ceará, com uma neoformação mamária. O diagnóstico inicial, obtido por meio de punção aspirativa por agulha fina, sugeriu a presença de carcinoma mamário. Exames de imagem como a radiografia torácica e a ultrassonografia abdominal não evidenciaram a presença de metástase no parênquima pulmonar e nos órgãos abdominais, respectivamente. O tratamento instituído foi a remoção cirúrgica da neoformação, pela técnica de mastectomia parcial bilateral. O exame histopatológico da massa evidenciou uma hiperplasia fibroepitelial. Diante disso, conclui-se que, apesar de raras, as neoformações mamárias em gatos do sexo masculino podem ocorrer, devendo, dessa forma, compor parte da lista de diagnósticos diferenciais para aumentos de volume na região ventral desses animais.(AU)
Mammary neoplasms represent the third most common neoplasm in queens, while in tomcats the incidence is rare. This study reports the case of a tomcat, not neutered, treated at the Veterinary Hospital of the State University of Ceará, with a mammary neoformation. The initial diagnosis, obtained through aspiration cytology, suggested the presence of mammary carcinoma. Imaging tests such as thoracic radiography and abdominal ultrasound, did not show the presence of metastasis in the lung parenchyma and abdominal organs, respectively. The chosen treatment was the surgical removal of the neoformation, using the bilateral partial mastectomy technique. Histopathological examination of the mass showed a mammary fibroepithelial hyperplasia. Therefore, it is concluded that, although rare, mammary neoformations in male cats can occur, thus, it should be part of the list of differential diagnoses for increases in volume in the ventral region of these animals.(AU)

This study aims to report the occurrence of two important parasites in farmed tambaqui Colossoma macropomum in the state of Tocantins, the acanthocephalan Neoechinorhynchus buttnerae and the dinoflagellate protozoan Piscinoodinium pillulare, also suggesting the main treatments to control them. The fish sampled for the study were infected by N. buttnerae, and P. pillulare, with prevalence from 100% and mean intensity from 51.4 to 354,264, respectively. This was the first report on the occurrence of such parasites in C. macropomum in the state of Tocantins. We emphasize the need to adopt good farm management and biosecurity practices to prevent pathogenic agents to enter or leave a property. Reported treatments with synthetic and natural products with positive results are also suggested to treat against those parasites in farmed C. macropomum.(AU)
