This study were carried out to investigate isolation of Pasteurella multocida from respiratory disorder piglets, to examine the biochemical properties and antimicrobial susceptibility. The results were summarized as follows; P multocida was isolated from 31($10.3\%$) of the 302 respiratory disorder or growing piglets of $4{\sim}10$ week olds. The majority of biochemical and cultural properties of the P multocida isolates were identical to those of the standard strains. The isolates were highly susceptible to norfloxacin($100.0\%$), enrofloxacin($96.8\%$) and ampicillin($87.1\%$), but resistant to streptomycin ($77.4\%$), penicillin($61.2\%$) and neomycin($54.8\%$).
