Porcine proliferative enteritis (PPE) is a transmissible gastroenteric disease caused by Lawsonia intracellularis. Clinically, PPE causes hemorrhagic diarrhea and sometimes death in growing pigs, but when the disease progresses to a chronic phase, the infected pig no longer displays significant symptoms. The purpose of the present studies were carried out to determine L. intracellularis in the pig farms and slaughter house, in Gyeongnam area. A survey of proliferative enteritis in pig was conducted using polymerase chain reaction (PCR) testing method, total 1,495 samples. PCR products showed a specific band at the 210bp, 329bp in the specimens of feces and mucosal scraping. Of 420 fecal specimens, 113 (26.9%) were identified as positive to PPE. Of 1,075 mucosal scraping specimens, 109 (10.1%) were identified as positive to PPE. Of total 1,495 specimens, 222 (14.8%) were identified as positive to PPE.
