Pasteurella multocida isolation from pigs with respiratory disease in Korea

Abstract

A total of 131 Pasteurella (P.) multocida strains were isolated from the lungs of 1,064 pigs with respiratory clinical signs nationwide during 2009-2010 and 2013-2014. The strains of P. multocida comprised 77.1% serotype A and 22.9% serotype D. Analysis of a recent P. multocida outbreak in Korean pigs showed that the isolation rate of serotype D decreased annually. The incidence of antimicrobial resistance, as measured using minimal inhibitory concentration values, has decreased recently. Overall, further studies to characterize P. multocida isolated from pigs in Korea are needed to prevent P. multocida infection in the Korean swine industry.
