Nationwide seroprevalence of Mycobacterium bovis and Mycobacterium avium in domestic sows and wild boars in Korea under a one health framework

Because ELISA-based serology reflects exposure rather than active infection, results should be interpreted with caution. In an international context, the observed seroprevalence in Korea was higher than that reported from intensive indoor production systems but lower than estimates from wildlife-rich ecosystems with established reservoir hosts. These findings indicate ongoing environmental exposure to mycobacteria in Korean suids and support the need for integrated One Health surveillance incorporating domestic pigs, wildlife, and complementary diagnostic approaches.
