The present study was conducted to investigate the incidence of pasteurella multocida infection in kyungbuk swine herds during the period from July 1989 to November 1989 and some properties of the isolated organisms. P. multocida was isolated from lungs of 155 slaughtered pigs, 43(27.7%) pigs were culture positive. The majority of biochemical and cultural properties of the P. multocida isolates were identical to those of the standard strains. The capsular serogroups and drug susceptibility of 43 isolates of P. multocida from pigs with pneumonic lesions were investigated. P. multocida isolates were typed for capsular serogroupes A by hyaluronidase inhibition of capsule and D by acriflavin auto agglutination. Most isolates(60.4%) were type A, 18.6% were type D, and the remaining 21.0% were untypable. In antimicrobial susceptibility test these isolates of P. multocida were susceptible in order of ampicillin (86.0%), trimethoprim sulfamethoxazole(83.7%), colistin(81.4%), chloramphenicol(79.1%), but the majority of them were resistant in order of streptomycin(30.2%), triple sulfa (4.6%).
