【摘要】：目的鉴定猪群体性肺部感染的病原菌。方法采用生化鉴定、小白鼠致病性试验、16SrRNA PCR鉴定及系统进化树分析。结果根据生化鉴定、小白鼠致病性试验及16SrRNA PCR鉴定。结果表明该菌为一株具有一定毒力的木糖氧化无色杆菌,同源性分析该菌与KF879922.1相似性为99.9%,命名为TLSY-1。结论该菌的鉴定将为仔猪肺炎病原鉴定提供新的依据。
[Abstract]:Objective To identify the pathogenic bacteria of pig group lung infection . The results were identified by biochemical identification , pathogenicity test of mice , PCR identification of 16SrRNA and analysis of phylogenetic tree . The results showed that the bacterium was a strain with a certain virulence . The results showed that the bacterium was a strain with a certain virulence . The homology was 99.9 % and named TLSY - 1 . Conclusion The identification of this bacterium will provide a new basis for the identification of the pathogen of piglet pneumonia .
