Prevalence and Characterization of Actinobacillus pleuropneumoniae Isolated from Korean Pigs

ABSTRACT

Actinobacillus pleuropneumoniae causes porcine pleuropneumoniae which is one of severe threats to the swine industry. In total, 54 strains of Actinobacillus pleuropneumoniae were isolated from 443 pigs between 2012 and 2013 in Korea. Isolates were classified into serotypes 1, 2, 5, 7, 12, and unclassified by multiplex PCR. Genotypes of isolates were divided into three groups according to the sequence of the omlA gene. The antimicrobial resistance rate of serotype 1 was slightly higher than that of serotype 5. In conclusion, to block and treat porcine pleuropneumonia, it is necessary to conduct ongoing characterization of A. pleuropneumoniae isolated from pigs.
