RISK FACTORS FOR BOVINE HERPESVIRUS 1 INFECTION IN CATTLE HERDS IN THE MARANHENSE AMAZON REGION, BRAZIL

This study was performed in order to determine the frequency of Bovine Herpesvirus 1 (BoHV-1), and the main factors related to the frequency of the infection in dairy cows not vaccinated against BoHV-1 from the Maranhense Amazon region, Brazil. Serum samples from 40 ranches were submitted to indirec...

description	This study was performed in order to determine the frequency of Bovine Herpesvirus 1 (BoHV-1), and the main factors related to the frequency of the infection in dairy cows not vaccinated against BoHV-1 from the Maranhense Amazon region, Brazil. Serum samples from 40 ranches were submitted to indirect ELISA test for detection of BoHV-1 antibodies. An epidemiological questionnaire was applied for each herd to investigate variables that could be associated with this infection. From 400 serum samples examined, 69.25% (n = 277) in 100% (n = 40) of the herds were positive for ELISA. Variables identified as risk factors such of age range of 3-7 years, absence of veterinary assistance and respiratory signs presented a statistical significance (P < 0.05) associated to BoHV-1 infection. These results indicate that BoHV-1 infection is high in the region studied and that factors related to characteristics of the ranches and to the livestock management practices were associated with the risk of infection by BoHV-1.Original Abstract: O presente estudo teve como objetivo determinar a frequencia e os fatores de risco para a infeccao pelo Herpesvirus Bovino Tipo 1 (BoHV-1) em femeas bovinas leiteiras na regiao Amazonica maranhense. Amostras de soro de animais nao vacinados contra o BoHV-1 e provenientes de 40 propriedades foram submetidas a tecnica de ELISA indireto. Em cada propriedade avaliada, aplicou-se ainda um questionario epidemiologico para investigar os fatores de risco que poderiam estar associados a infeccao pelo virus. Das 400 amostras de soro analisadas, 69,25% (n = 277) foram reagentes com a deteccao de bovinos sorologicamente positivos em 100% (n = 40) das propriedades. Dentre os fatores de risco avaliados, faixa etaria entre 3 a 7 anos, ausencia de assistencia veterinaria e sinais respiratorios apresentaram significancia estatistica (P < 0,05) associada a infeccao pelo BoHV-1. Os resultados do estudo indicam que a frequencia de anticorpos contra o BoHV-1 foi elevada na regiao Amazonica maranhense e que os fatores relacionados as caracteristicas das propriedades e ao manejo foram associados ao risco de infeccao pelo BoHV-1.
