Abstract

The present study was conducted to investigate the species-specific gene detection and antimicrobial susceptibility of Pasteurella (P.) multocida isolated from pneumonic lung lesions of Youngnam swine herds during the period from July 2006 to September 2007. A total of 91 (36.3%) strains of P. multocida were isolated from 251 pneumonic lung lesions. The species-specific P. multocida gene was detected at 460 bp amplicons by PCR. The P. multocida tested was susceptible to florofenicol (93.4％), amikacin (91.2％), cephalothin (87.9％), cefoxitin (84.6％), ofloxacin (80.2％) and norfloxacin (65.9％) in 27 antimicrobial susceptibility tests. Most of strains were resistant to more than 5 drugs.

영남지방 5개 농장에서 사육중인 돼지 251두의 폐렴병소로부터 P. multocida를 분리한 결과 91주의 P. multocida가 분리되어 분리율은 36.3%로 나타났다. 생화학적 특성을 조사한 후 PCR로 최종 확인한 결과 P. multocida species-specific 유전자 460 bp의 특이 증폭산물을 관찰하였다. 분리균 91주의 P. multocida에 대한 약제 감수성 검사 결과 amikacin (91.2%), cephalothin (87.9%), cefoxitin (84.6%), florofenicol (93.4%), norfloxacin (65.9%), ofloxacin (80.2%) 등의 약제에 비교적 높은 감수성을 나타내었다. 또한 대부분의 분리주는 5종 이상의 약제에 대해 다재 내성 양상을 나타내었다.
