ABSTRACT
Bovine alphaherpesvirus type 1 (BoHV-1) is the etiological agent responsible for serious infections that compromise the respiratory and genital tracts of affected cattle. In order to estimate the seroprevalence of BoHV-1 and to identify the associated risk factors in dairy farms in the city of Senador Guiomard, Acre, Brazil, the present study was carried out through the analysis of 180 blood serum samples submitted to the screening of anti-BoHV-1 by the virus neutralization test (VN) and by means of the evaluation of the epidemiological questionnaire applied in the eight investigated properties. The prevalence of seropositivity for BoHV-1 was 61.1%, ranging from 43.3 to 86.2% among the analyzed properties. The variable absence of veterinary assistance showed statistically significant association (odds ratio — OR = 2.10; p < 0.001) with alphaherpesvirus infection. The results demonstrate that the frequency of BoHV-1 is high and needs to be controlled through prophylactic and health management measures.
