Abstract: :In this study, three young pigs in a large pig farm from Tianjin were selected as the research objects. The results of the pathological changes of the organs, the isolation and identification of morphology, the culture medium, the biochemistry, 16S rRNA amplification and PCR were carried out to identify pathogenic bacteria. The bacteria were identified as pathogenic bacteria by animal pathogenicity test. The results showed that the cause of swine’s death was Actinobacillus pleuropneumoniae. Then drug sensitivity test showed that APP was sensitive to cefoperazone; moderately sensitive to chloramphenicol, amoxicillin and ciprofloxacin; and resistantto doxycycline, streptomycin, kanamycin, penicillin, tetracycline, ampicillin, vancomycin, and gentamicin. This experiment provides a theoretical basis for the clinical diagnosis and medication of APP.

Key words: Actinobacillus pleuropneumoniae, 16S rRNA, isolation and identification, drug sensitivity test
