Abstract

Porcine salmonellosis is an economically important disease affecting the global pig industry today. Salmonella (S.) Typhimurium is highly contagious and may rapidly spread within pig populations of herd. To investigate the prevalence of porcine salmonellosis in Jeju, a total of 12,885 blood sera of 96 pig farms from 2009 to 2012 were analyzed by microplate agglutination test. Antibodies to S. Typhimurium were detected in all of pig farms tested in Jeju Province, and the mean of seropositive rate of individual pig was 18.8%. The mean seropositive rate of S. Typhimurium in sows (46.7%) was 7 times higher than that of weaned or growing pigs (6.7%). The lowest seropositive rate (3.0%) was detected in 40 day-old pigs, and this result might be closely associated with the marked decrease of maternal passive immunity. The seropositive rate in winter (42.7%) was higher than in other seasons.
