Resumo: A study was conducted to measure the prevalence of hemagglutination-inhibition (HI) - neutralizing antibodies against two arboviruses (Chikungunya - Japanese encephalitis virus) in horses of Java, Indonesia. Blood specimens were collected from a sample of 112 horses at two stables: Pulo Mas, a racing track-horse complex, located in a residential area in North Jakarta, - Pamulang, a riding school, located in a rural environment of West Jaya. Sera were tested by the HI assay - plaque reduction neutralization test. JEV antibodies were detected by HI in 58 (52%) of the horses, while only 11 (10%) had Chikungunya antibodies by HI. The proportion of Pamulang horses infected with JEV (66%) was significantly higher than found among Pulo Mas horses (40%) screened (p < 0.01). Of the 58 horses with JEV antibodies by HI, 52 (90%) were found to have specific neutralization antibodies to JEV. HI - neutralization tests on horse sera indicated that the risk to alpha virus infections was minimal in horses surveyed from Java. However, there was a high risk of JEV infection among the same population.
