The present study was conducted to investigate the incidence of Actinobacillus pleuropneumoniae infection in the pneumonic lungs of slaughter pigs from July 1996 to June 1997 and to examine the biochemical and cultural properties, the antimicrobial susceptibility and serotypes of the isolates.
The biochemical and cultural properties of A pleuropneumoniae isolated from the pneumonic lungs of swine were identical to those of the reference strains used.
Twenty-four(8.1%) strains of A pleuropneumoniae were isolated from 298 pneumonic lungs of slaughter pigs.
The majority of isolates were high by suscepible to ampicillin, cephalotin, oxacillin and moderately susceptible to cefazolin, gentamicin, kanamycin, chloramphenicol, although the majority of them were resistant to neomycin streptomycin, erythromycin, lincoinycin, and sulfamethoxazole.
Of the 24 A pleuropneumoniae isolates, 12(50.0%) were serotype 5, 11(45.8%) were serotype 1 and 1(4.2%) was serotpye 7.
