ABSTRACT
This study was aimed at investigating the prevalence of antibodies against, influenza virus (EIV), equine viral arteritis virus (EVAV), and herpesvirus (EHV) among horses in Rio Grande do Sul (RS) state, Brazil. Serum samples from horses of 65 counties of northern and northwestern RS, were tested by inhibition hemaglutination test (HI) for EIV and by virusneutralization test (VN) for EVAV and EHV antibodies. From 1506 samples, 986 (65.4%) had antibodies to EIV (titers ranging from 10 to 1280), 33 (2.2%) were positive to EVAV . Among the 65 counties, 55 (84.6%) presented at least one positive animal to EIV, 15 (23%) to EVAV, and 12 (18.5%)
