Feline calicivirus (FCV) and feline herpesvirus type 1 (FHV-1) are the two primary causes of upper respiratory tract disease in cats. The aim of this study was to demonstrate the distribution of FCV and FHV-1 among the feline population of several counties in Rio Grande do Sul State, Brazil. To this end, conjunctival and nasal swabs were collected from 302 cats from different locations, including households, breeding catteries, veterinary clinics, animal hospitals and experimental research facilities. The samples were collected between July 2006 to June 2009. The virus isolation was performed in CRFK cells and, subsequently, the identification was confirmed by PCR. FCV, FHV-1, or both were isolated from 55 cats from 28 different locations. FCV alone was... |

ABSTRACT: This study aimed to characterize the outbreaks of equine infectious anemia (EIA) identified, between the years 2009 and 2015, in the western region of the state of Rio Grande do Sul, Brazil. We identified 26 positive horses on 24 properties. Each positive property was considered an outbreak of the disease. The diagnoses were made using the agar gel immunodiffusion (AGID) test as a part of the sanitary checks conducted during animal transportation or certification of the horse´s sanitary status. The positive properties included farms or horse barns, and the infected animals were used for ranch work, sports, or reproduction. One outbreak was identified in animals that were being illegally transported from Argentina to Brazil. Fifteen outbreaks... |

ABSTRACT: The serological responses induced by four commercial inactivated Uruguayan vaccines against bovine alphaherpesviruses (BoHV)-1 and -5 and bovine pestiviruses (BVDV-1, BVDV-2, and HoBiPeV) were evaluated in sheep. Thirty-seven sheep were immunized twice (day 0 and 25) and their serum samples were tested at different intervals (days 0, 25, 40, 60, and 90) post-vaccination (PV). Among the four vaccines tested, only one (G4) could induce the production of moderate neutralizing antibody titers against BoHV-1 and -5 and BVDV-1 and -2. The G3 vaccine showed a neutralizing serological response against the bovine alphaherpesviruses only. The G1 and G2 vaccines produced extremely low levels of antibodies in a few vaccinated animals only (geometric mean... |

Um equino, sem raça definida, macho com três anos de idade apresentou múltiplos nódulos na pele, em diversas regiões do corpo. As lesões localizavam-se predominantemente nos lábios, nas bochechas, na região submandibular e na região inguinal direita. Os tumores caracterizavam-se como sarcoides dos tipos misto, fibroblástico, verrucoso e oculto. Histologicamente apresentaram proliferação de fibroblastos dérmicos, muitas vezes ulcerado, com ou sem hiperplasia pseudoepiteliomatosa da epiderme e formação de pequenos grupos isolados de fibroblastos neoplásicos na derme superficial. Três amostras de tecido foram submetidas à extração de DNA e amplificação por PCR com oligonucleotídeos iniciadores genéricos direcionados para uma região interna do gene L1 dos... |

ABSTRACT This study sought to evaluate the occurrence of lesions suggestive of hydatidosis, cysticercosis, and tuberculosis in animals slaughtered under sanitary inspection of the Divisão de Inspeção de Produtos de Origem Animal (DIPOA), in the state of Rio Grande do Sul. Condemnation data between the years 2009 and 2017 were obtained from Secretaria da Agricultura Pecuária e Irrigação (SEAPI) and presented according to the administrative regions established by SEAPI. In that period, 7,509,544 cattle were slaughtered and condemnations occurred in all regions of the state at varying levels. The mean condemnation values showed the presence of hydatidosis in 523,399 (6.97%), cysticercosis in 92,277 (1.23%), and tuberculosis in 10,595 (0.14%) cattle carcasses.... |

Duas amostras brasileiras do vírus da Diarréia Viral Bovina tipo 2 (BVDV-2) foram inoculadas em bezerros com o objetivo de avaliar a sua virulência e estudar a patogenia da infecção. Previamente à inoculação, os animais foram imunodeprimidos com dexametasona. Quatro bezerros com idades entre 45 e 90 dias (grupo A) foram inoculados com a amostra SV-260 (n=2) ou LV-96 (n=2) e quatro bezerros com 6 a 8 meses de idade foram inoculados com a amostra SV-260 (grupo B). Após a inoculação, os bezerros do grupo A apresentaram anorexia, depressão, hipertermia, sinais de infecção respiratória e diarréia profusa, acompanhada de melena em dois animais. Os sinais respiratórios e digestivos progrediram, e os animais morreram ou foram sacrificados in extremis entre os dias... |
