| ABSTRACT P34 is an antimicrobial peptide produced by Bacillus sp. P34, isolated from the intestinal contents of a fish from the Amazon basin. This peptide showed antibacterial properties against Gram-positive and Gram-negative bacteria and was characterized as a bacteriocin like substance. It was demonstrated that the peptide P34 exhibited antiviral activity against feline herpesvirus type 1 in vitro. The aim of this work was to evaluate P34 for its antiviral properties in vitro, using RK 13 cells, against the equine arteritis virus, since it has no specific treatment and a variable proportion of stallions may become persistently infected. The results obtained show that P34 exerts antiviral and virucidal activities against equine arteritis virus, probably... |

| Antibody titres to canine distemper virus (CDV) and canine parvovirus (CPV) were measured in 132 dogs: 80 had been vaccinated at least once, 22 had not been vaccinated, and 30 had unknown vaccination history. Serum antibody titers were measured by means of serum neutralization (CDV) or hemagglutination inhibition (CPV). Serum CDV titers >20 and serum CPV titers >80 were considered protective. Protective antibodies to CDV were present in 40.1% of the population: 39.8% of the vaccinated dogs, 31.8% unvaccinated, and in 46.6% of the dogs with unknown vaccination history. Protective antibodies to CPV were present in 90.9% of the dogs: 93.7% of the vaccinated dogs, 90.9% of the unvaccinated, and 83.3% of the dogs with unknown vaccination history. |

| No Brasil existem poucos estudos sobre a ocorrência da infecção pelo vírus da imunodeficiência felina (FIV), assim como a determinação dos subtipos circulantes, o que é indispensável para o desenvolvimento de vacinas e novos testes diagnósticos. O presente trabalho investigou a ocorrência da infecção pelo FIV entre os anos de 2010 e 2011 em gatos domésticos submetidos a atendimento clínico na cidade de Pelotas e região. Amostras de sangue total de 70 animais, incluindo suspeitos (28) ou não suspeitos (42) da infecção pelo FIV, foram submetidas à reação de PCR nested. Os resultados indicaram uma frequência de infecção de 15,7% (11/70) e a análise dos fatores associados (sexo, idade e condição clínica) evidenciou uma maior ocorrência em gatos com idade... |
