Porcine reproductive and respiratory syndrome virus and Mycoplasma hyopneumoniae are account as economically important pathogens in swine business worldwide. The studies of these two pathogens in Thailand were restricted on domestic pigs in swine industry and the status of these pathogens in wild boars is currently not available. This cross-sectional study aimed at estimating the seroprevalence of antibodies to these agents in captive wild boars. Fifty-two serum samples were collected from wild boars reared in three different types of captive settings including a commercial wild boar farm, a wildlife breeding research station and a zoo. All serum samples were examined for antibodies to porcine reproductive and respiratory syndrome virus and Mycoplasma hyopneumoniae by ELISA methods. The results revealed that the highest true prevalence of both pathogens was found in sera derived from wild boars in wildlife breeding research station at 69 and 66% for porcine reproductive and respiratory syndrome virus and Mycoplasma hyopneumoniae respectively. This study is the first to reveal seroprevalence of antibodies against porcine reproductive and respiratory syndrome virus and Mycoplasma hyopneumoniaein wild boar populations in Thailand. More detailed investigations are critically needed.
