Abstract

Despite the large wild boar population in South Korea, research on infectious diseases is limited. We investigated the prevalence of infectious diseases caused by Porcine Circovirus Type 2 (PCV2), Aujeszky's Disease Virus (ADV), Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), and Mycoplasma hyopneumoniae in 400 wild boars in South Korea. PCV2 antibodies were detected in 223 samples, antigens in 112, and both in 101. ADV and PRRSV antibodies were detected in one and three samples, respectively. M. hyopneumoniae antibodies were identified in 28 samples. PCV2 was detected in all nine regions, M. hyopneumoniae in five, PRRSV in three, and ADV in one. Infectious-disease monitoring is crucial to safeguard wild boars.
