Abstract

REASONS FOR PERFORMING STUDY: A silent cycle of equine herpesvirus 1 infection has been described following epidemiological studies in unvaccinated mares and foals. In 1997, an inactivated whole virus EHV-1 and EHV-4 vaccine was released commercially in Australia and used on many stud farms. However, it was not known what effect vaccination might have on the cycle of infection of EHV-1. OBJECTIVE: To investigate whether EHV-1 and EHV-4 could be detected in young foals from vaccinated mares. METHODS: Nasal and blood samples were tested by PCR and ELISA after collection from 237 unvaccinated, unweaned foals and vaccinated and nonvaccinated mares during the breeding season of 2000. RESULTS: EHV..
