Abstract

In order to investigate the prevalence of viral diseases in vaquejada horses, samples were collected from Quarter Horse and Paint Horse breeds (males and females, aged between 2 and 15 years) from rural and urban areas of Mossoró, Rio Grande do Norte, Brazil were collected. The number of samples collected and tested varied with the techniques used: 132 serum samples were tested for vesicular stomatitis (VS) and equine viral arteritis (EVA), 118 for western and eastern equine encephalomyelitis (WEE/EEE), 114 for equine herpesvirus 1 (EHV-1), and 61 for equine influenza (EI). The techniques used varied according to the disease studied: tests for VS (Ribeirão and Alagoas strains), EVA, EHV-1, and WEE/EEE were performed using the seroneutralization technique in Vero cell cultures, while the test for for EI type-2 (H3N8) was performed using the hemagglutination inhibition technique. The following results were obtained: 39 (29.55%) and 6 (4.54%) VS-positive horses (n=132) harbored the Alagoas and Ribeirão strains, respectively; no animal tested positive for EVA (n=132); 11.01% (n=13) and 0.84% (n=1) animals tested positive for EEE and WEE (total n=118), respectively; and 22 out of 114 (19.29%) horses tested positive for EHV-1. The history of respiratory and reproductive diseases was statistically significantly (p = 0.02) related to the presence of antibodies against EHV-1. This is the first report of the seroprevalence of viral diseases in vaquejada horses in Rio Grande do Norte.
