Bovine Herpesvirus-1 antibodies levels and associated Risk Factors in unvaccinated Dairy Herds from tropical wet weather, Ecuador

In order to determine the antibodies levels against Bovine Herpesvirus type 1 (BHV-1) and associated risk factors in unvaccinated dairy herds of tropical wet weather Ecuador, an investigation was carried out thirteen production units (PU), Chone Canton, Province Manabí. The sample size calculate by cluster sampling variables be evaluated were frequency, age, sex, ocular or vulvovaginal lesions, breed PU. One hundred eighty three blood samples taken from jugular caudal vein labeled for transfer laboratory. tubes centrifuged at 3,220 g 15 minutes sera transferred Eppendorf that once stored –20°C until processing. Antibodies HBV-1 measured through competitive ELISA technique, calculated with simples statistical. estimated Odds ratio relative risk, significance level Chi-square. general frequency 58.47 %. According 28.57 % animals under two years old (yr.old) 67.38 cattle over yr.old. males showed 18.18 females 82.61 determined (P<0.05) age a significant 3.31 2.32, respectively. Western lowlands have high BHV-1, yr.old highest presenting infectious bovine rhinotracheitis (IBR).
