Characterisation of Pasteurella multocida isolates from pigs with pneumonia in Korea.

P. multocida subspecies multocida, biovar 3, and capsular type A was the most prevalent isolate in this study, and our findings indicated the emergence of capsular type F in Korea. Moreover, prudent use of oxytetracycline and florfenicol is required because of the identified high resistance rates. Further studies are required for continuous monitoring of the antimicrobial resistance, prevalence, and epidemiological characterisation of P. multocida, and experimental infection models are needed to define the pathogenicity of capsular type F.
