Resumo: |
The objective of this work was to determine the prevalence and risk factors associated with infection by bovine herpesvirus type 1 (BHV-1) in cattle herds, in Garanhuns microregion, State of Pernambuco. Three hundred eighty samples of blood serum from animals aged over 24 months from dairy herds not vaccinated against BHV-1 and from 20 properties, located in 19 municipalities were analyzed. For serological diagnosis of infection with BHV-1, serum neutralization test (SN) was used. In each farm, an epidemiological questionnaire was applied to analyze risk factors with objective questions about the characteristics of production and aspects of hygienic-sanitary and reproductive management. The prevalence was 79.5% (302/380; CI: 75.1% - 83.4%) of the 20 sampled properties, all had at least one positive animal, with prevalence in herds ranging from 46.2% to 100.0%. The variables considered risk factors for HBV-1 in the logistic regression analysis were: i) bulls used in the reproductive period in females with reproductive problems (OR = 3.84, CI = 2.19 to 6.72; p <0.000); ii) Consortium creating goats / sheep with cattle (OR = 2.90, CI = 1.00 to 8.37; p = 0.048); and iii) herd size <50 animals (OR = 3.62, CI = 1.66 to 7.85; p = 0.001). These results indicate that infection with BHV-1 is distributed in the studied area and that control measures should be adopted in the herds. The epidemiological data obtained will serve as a basis for planning control strategies, as the identified risk factors are related to the creation and hygienic-sanitary management system. |
