Keywords:Prevalence, Uruará (PA), Equine infectious anemia, Animal arteritis
AbstractEquine infection anemia virus (EIAV), Equine arteritis virus (EAV) and Equine herpesvirus 1 (EHV 1) are the causal agents of diseases which may bring economical losses. The aim o of this study was to estimate the prevalence of herds and animals infected with EIA, EAV and EHV in Uruará municipal district, Pará State-Brazil. Antibodies against EIAV were detected by the immunodiffusion test and those against EAV and HEV-1 by the serum neutralization test. Sample size was estimated from 2069 holder farms that raised Equidae and did not vaccinate against EAV and EHV. A 90% confidence level was adopted with 15% precision and 50% estimated prevalence. The herd was considered positive when it had at least one positive animal. The following prevalence of serum reactors animals were observed: VAIE: 17,71% (IC 10,67 - 26,83%), HVE-1: 17,71% (IC 10,67 - 26,83%) and VAVE: 0,00% (IC 0,00 - 3,77%). The following prevalence of positive herds were observed: VAIE: 53% (IC 38,12 - 68,12%), HVE-1: 40.62% (IC 25.96 - 56.65%) and VAVE: 0% (IC 0 - 6.94%).
