Sero-prevalence of serological of Lawsonia intracellularis in domestic pigs in South Korea

Proliferative enteropathy (PE) of pigs mainly been caused by Lawsonia intracellularis. To investigate the prevalence of L. intracellularis in South Korea, serum samples of 2,356 pigs from nine province domestic farms were tested using IgGs against ELISA kit. During 2017 to 2019, among of every age groups, the older age groups (>120days and sow) had significant higher positive rates than younger groups. The objective of the current study was to measure the seroprevalence of antibodies to L. intracellularis in different age groups in pigs in South Korea as a more sensitive measure of detection in this country.
