肉鸡中铜绿假单胞菌的研究

目的调查屠宰前肉鸡铜绿假单胞菌的携带情况,为铜绿假单胞菌流行病学的调查和相关疾病的预防控制提供依据。方法采集49份屠宰前肉鸡的肛拭子,并分离可疑菌株,对分离到的菌株进行氧化酶实验、绿脓菌素试验和VITEK生化鉴定实验。结果从49份屠宰前肉鸡中分离出8株可疑菌株,阳性检出率为16.3%。通过形态学观察、生化鉴定,8株可疑菌株均被鉴定为铜绿假单胞菌。8株可疑菌株的生化反应结果符合铜绿假单胞菌的生化反应特点。结论健康肉鸡可携带铜绿假单胞菌。铜绿假单胞菌可作为一种食源性致病菌而危害人类健康。

Study on Pseudomonas aeruginosa in chicken

Objective To detect Pseudomonas aeruginosa in adult chicken,and provide basis for epidemiological investigation or for the control of related diseases.Methods Suspicious strains were isolated from 49 anus swab samples of adult chicken before slaughtering and examined by oxidase test,pyocyanin test and biochemical identification.Results Eight suspicious strains were isolated from anus swabs,and the positive rate was 16.3%.According to morphological observation,oxidase test,pyocyanin test and biochemical identification,8 suspicious strains were identified as pseudomonas aeruginosa.Conclusion Pseudomonas aeruginosa could be carried by healthy chicken.As a foodborn pathogen,pseudomonas aeruginosa do harms to the human.
