Neste experimento, 12 novilhos de diferentes raças, com idade de 18 a 24 meses foram submetidos a secção do ligamento apical para provocar desvio de pênis, para posterior correção cirúrgica. Os animais foram distribuídos em dois grupos de igual número e submetidos ao implante de borracha de silicone na extremidade livre do pênis para correção do desvio. Nos animais do grupo 1 a prótese foi implantada no corpo cavernoso e entre o ligamento apical e túnica albugínea. Nos animais do grupo 2 a prótese foi implantada entre o ligamento apical e túnica albugínea. Em todos os animais o material implantado foi bem tolerado com formação de discreta reação inflamatória, sendo encapsulado por tecido conjuntivo fibroso, ocasionando adesão resistente e uniforme entre o ligamento apical e túnica albugínea. Os bovinos quando observados em presença de fêmeas em cio não apresentaram desvio de pênis e modificações do comportamento sexual. O método mostrou-se satisfatório podendo ser indicado como uma opção a mais para corrigir desvios ventral e lateral de pênis de bovinos, em qualquer das duas técnicas empregadas.

This study describes an outbreak of avian poxvirus disease in previously pox-vaccinated turkeys in Brazil. The turkeys had suggestive gross lesions of cutaneous avian poxvirus in the skin of the head and cervical area without changes in the flock mortality rates. In the slaughterhouse, 30 carcasses were removed from the slaughter line to collect tissue from cutaneous lesions for histological analyses and characterization of the virus. The virus was identified by conventional polymerase chain reaction (PCR) and subsequent gene sequencing. Acanthosis, hyperkeratosis, and hydropic degeneration were seen on skin histopathology. Eosinophilic intracytoplasmic inclusion bodies (Bollinger) on keratinocytes were observed in 46.6% of the samples. Avian poxvirus DNA was detected on PCR in 83.3% of the total samples. PCR associated with histopathology had 93.3% of positivity for avian poxvirus. In the phylogenetic study, samples show 100% matching suggesting that the outbreak occurred by a single viral strain and was different from those strains affecting other wild birds such as canaries and sparrows. A single mutation (Adenine for Guanine) was detected in our study’s strain and in the strains of turkey, chickens, and vaccine strains published in GenBank. Also, when the sequence strain of the present study and sequences from GenBank of canarypox and sparrowpox strains were aligned, a Thymine was found replacing the Adenine or Guanine. The in ovo vaccination method as single-use in turkeys of this study apparently did not provide adequate protection against avianpox disease, but additional vaccination administered by wing-web when turkeys were 45-60 days old in the new flocks controlled the disease. In the subsequent year, new cases of this disease were not found. It was not possible to confirm the source of the virus strain, but infection with a field strain derived from chickens is one possibility, considering the poultry farm population in the area and biosecurity aspects. For wide characterization of avipoxvirus and differentiation among strains, the complete sequence of the viral genome is required.

Classificado no gênero Morbillivirus da família Paramixoviridae, o vírus da cinomose possui RNA de fita simples de polaridade negativa, é causador de doença multissistêmica, altamente contagiosa e grave dos cães e carnívoros selvagens, e com elevado índice de mortalidade em animais não vacinados ou com falhas vacinais. Com o objetivo de avaliar as alterações histopatológicas no coração, particularmente na região do miocárdio ventricular esquerdo, de cães naturalmente infectados com o vírus da cinomose, foram estudados 35 animais, de ambos os sexos e com idades variadas. Das 35 amostras enviadas ao Laboratório de Medicina Veterinária Preventiva do Hospital Veterinário de Uberaba, 100% (35/35) mostrou-se soropositivas para a cinomose (técnica de imunoensaio em fase sólida) e tiveram no miocárdio ventricular esquerdo as seguintes alterações histopatológicas: miocardite, degeneração hialina, hiperemia e hemorragia, com 42,8% (15/35), 31,4% (11/35), 14,3% (5/35) e 11,4% (4/35), respectivamente. Tendo utilizado o teste Qui-Quadrado com nível de significância de 0,05, conclui-se que existe alta correlação (p=0,02) entre os animais infectados com o vírus da cinomose e as alterações histopatológicas observadas no miocárdio ventricular esquerdo.

Chemodectomas are malignant or benign neoplasms of chemoreceptor cells, which are commonly located in the base of the dog’s heart. This paper reports a case of chemodectoma in an 11 years old male dog of Fila Brasileiro breed, in Uberaba city. The animal has a frequent cough, dyspnea and members edema. Carotid body chemodectoma was diagnosed on lung areas, liver, spleen and pancreas metastases. The chemodectoma causes still unknown, but most of affected animals, has a chronic respiratory disease, associated with the neoplasms.

Liver is the largest gland in the body, which has a great diversity of functions. It is parenchymal and glandular. Chicken livers may undergo several alterations, including bacterial, parasitic, neoplastic, among other. Chicken meat and its byproducts are sources of diseases transmitted to humans. That is why in order to ensure the public health, meat and viscera are considered unfit for consumption. In this research were examined, macroscopically and microscopically, 100 chicken livers, with an average age of 33 days, weight 1,3 to 1,6 kg, that led the loss of the entire carcass, in line B of a slaughterhouse inspection, located in the region of the Triângulo Mineiro. Macroscopically, it was possible to observe a coherence with the data describe by the literature such as liver with increased volume, reddish, greenish, yellowish, whitish spots and friable. Microscopically, the lesions found in most livers were infiltrated with heterophile, followed by neoplastic cells clustered. Thus it was possible to conclude that the etiologic diagnosis in macro and microscopically alterations is compatible with colibacillosis (80%) and leucosis myeloid (20%) respectively.
