| A bumblefoot outbreak with different prognosis according to host species was studied in captive aquatic avian species. Six wood ducks (Aix sponsa), three scarlet-ibis (Eudocimus ruber), two black-swans (Cygnus atratus), five white-faced ducks (Dendrocygna viduata) and two roseate spoonbills (Platalea ajaja) were kept in a common pen with abrasive pavement pond margin, predisposing to podal skin wear. Incoordination and mortality occurred in the two roseate spoonbils and one black swan. Coagulase-positive penicillin-resistant Staphylococcus aureus was isolated from the synovial fluid and from the liver. All birds sharing the pen presented active or cicatricial foot lesions, indicating a possible challenge to the environmental Staphylococci. However, except... |

| ABSTRACT: A standardized immunochemistry method for the diagnosis of clostridial myonecrosis was applied to 38 formalized tissue samples from ruminants with clinical and post mortem history suggestive of blackleg or gas gangrene. The diagnosis of clostridial myonecrosis was confirmed in 37 out of 38 (97.4%) samples tested. Clostridium chauvoei and Clostridium perfringens type A were the most common agents found alone, being detected in ten (26.3%) and six (15.8%) samples, respectively. The other cases showed an association of two or three clostridia, with C. perfringens type A detected in 11 (29%) cases. Based on the findings of the present study, polyvalent vaccines against clostridial infections of animals incorporating C. perfringens would be more... |

| Um bovino Guzerá, fêmea, adulto, com histórico de insuficiência cardíaca congestiva direita de duração de duas semanas, morreu durante o transporte ao hospital veterinário. À necropsia, o lobo pulmonar cranial esquerdo estava moderadamente aumentado de tamanho e firme. O parênquima do lobo afetado era branco e continha múltiplas áreas de 0,3 a 1,5cm de diâmetro, amareladas e caseosas. Alterações semelhantes foram observadas nos linfonodos mediastínicos e brônquicos, no pericárdio parietal, no epicárdio e na adventícia da artéria pulmonar. Histologicamente, a massa tecidual do lobo pulmonar era constituída por células epiteliais neoplásicas de padrão acinar, com duas ou mais camadas celulares, algumas com projeções papilares intraluminais. A anisocariose... |

| ABSTRACT This study was conducted to evaluate the effect of two levels of vitamin D3 with or without 1,25- dihydroxycholecalciferol (1,25(OH)2D3) on live performance and bone quality of broiler chickens. For that, we used a completely randomized design in a 2 × 2 factorial arrangement, with eight replicates of 30 Cobb®500 male broiler chicks each (n = 960). The two levels of vitamin D3 and the addition or not of 0.5 μg 1,25(OH)2D3/kg were considered as main factors. The vitamin D3 levels were: 2500/2000 IU/kg and 1250/1000 IU/kg for the starter (1 to 21 days) and grower (22 to 40 days) phases, respectively, with the first representing the levels used in industry (100%) and the second, a reduction in 50% of those levels. The 1,25(OH)2D3 source was Solanum... |

| Abstract Thirty-six isolates of psittacid herpesvirus (PsHV), obtained from 12 different species of psittacids in Brazil, were genotypically characterized by restriction fragment length polymorphism (RFLP) analysis and PCR amplification. RFLP analysis with the PstI enzyme revealed four distinct restriction patterns (A1, X, W and Y), of which only A1 (corresponding to PsHV-1) had previously been described. To study PCR amplification patterns, six pairs of primers were used. Using this method, six variants were identified, of which, variants 10, 8, and 9 (in this order) were most prevalent, followed by variants 1, 4, and 5. It was not possible to correlate the PCR and RFLP patterns. Twenty-nine of the 36 isolates were shown to contain a 419 bp fragment of... |

| Doses únicas de 10 a 25g/kg das folhas verdes de Phytolacca decandra foram administradas oralmente a 11 ovinos. Dois desses ovinos (20 e 25g/kg) morreram 6 horas após a ingestão da planta e os outros nove adoeceram levemente e se recuperaram. Um outro ovino recebeu 4 doses diárias de 5g/kg da mesma planta. Esse ovino e outros dois usados como controles não adoeceram. Os principais sinais clínicos nos ovinos afetados foram dor abdominal, inquietação, manoteio, distúrbios respiratórios, tremores e hiperestesia. As alterações macroscópicas mais importantes em dois ovinos necropsiados estavam restritas ao sistema digestivo e consistiam de avermelhamento difuso da mucosa do rúmen, retículo, abomaso e intestino delgado. Microscopicamente, as alterações eram... |

| Uma cadela, sem raça definida, de quatro anos apresentou, no período de dois meses, anorexia, emagrecimento progressivo e letargia. Os exames laboratoriais constataram anemia intensa e azotemia e, na ultra-sonografia, observou-se uma massa na região mesogástrica. Após tentativa de tratamento clínico sem resposta, optou-se pela eutanásia. Macroscopicamente, observaram-se acentuada palidez das mucosas, pobre estado nutricional e desidratação. Os linfonodos pré-esternais estavam aumentados e nos lobos esquerdos do fígado, pâncreas, linfonodos regionais, baço e duodeno havia múltiplos nódulos tumorais branco-amarelados. Microscopicamente, na medula óssea, baço, linfonodos e fígado havia infiltração tumoral por células blásticas com pouco citoplasma, núcleo... |

| O presente relato descreve um caso de mielolipoma adrenal bilateral em uma cadela Poodle de 13 anos de idade. O cão morreu por peritonite séptica aguda, decorrente de ulceração e perfuração intestinal por corpo estranho linear. O neoplasma foi achado incidentalmente durante a necropsia. Macroscopicamente, as adrenais estavam redondas e com volume e aumentados. Ao corte elas eram friáveis, vermelho-amarronzadas, intercaladas por áreas branco-amareladas levemente proeminentes. Histologicamente, extensas áreas do parênquima continham adipócitos bem diferenciados, células hematopoéticas e macrófagos com hemossiderina, achados característicos de mielolipoma adrenal. |

| ABSTRACT: 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 patient’s 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... |

| ABSTRACT: A three-year-old female African pygmy hedgehog (Atelerix albiventris), born and domiciled in Brazil, presented apathy, prostration, and difficulty to stay standing. Its parents were siblings but did not present clinical signs related to this condition. As its clinical condition worsened, the animal was euthanized and referred for necropsy. No gross lesions were found in the central nervous system (CNS). Histologically, there was vacuolation with axonal degeneration in the white matter of the CNS and in peripheral nervous tissue. The Kluver-Barrera (KB) stain confirmed demyelination in vacuolated areas. Immunohistochemistry using several neural markers confirmed astrocytosis and microgliosis associated with vacuolated areas. In addition, there... |
