Abstract

In grower pigs, enteric diseases are major economic problem in swine industries. Enteric diseases are attributed to numerous bacterial agents, such as Lawsonia (L.) intracellularis, Brachyspira (B.) hyodysenteriae, B. pilosicoli and Salmonella spp. Therefore we investigated the prevalence of enteric pathogens and found out the correlation of infectious agents in enteric diseases of grower pigs in Jeju-do using polymerase chain reaction (PCR) method. A total of 509 fecal samples of grower pigs from 49 pig farms of Jeju-do were collected from May 2006 to June 2007. Diagnostic confirmation was performed based on the detection of bacterial DNA from fecal samples. Based on the PCR methods, B. pilosicoli, B. hyodysenteriae, L. intracellularis and Salmonella spp. were detected in 82 (16.1%), 38 (7.5%), 15 (2.9%), and 12 (2.4%) fecal samples from grower pigs in Jeju-do, respectively. Single infection of enteric pathogen and mixed infection with more than 2 pathogens were detected in 110 (86.6%) and 17 (13.4%) grower pigs, respectively. These results suggest that B. pilosicoli and B. hyodysenteriae are main pathogens of diarrheal disease among grower pigs in Jeju-do. Therefore, accurate control strategy for enteric pathogens should be warranted in Jeju-do.
