目的调查九江市首例布鲁氏菌病感染来源和传播的危险因素。方法采用现场流行病学调查和血清学检测进行调查。结果采集病例家属样本7份、密切接触人员标本5份和可疑动物标本1份,虎红平板凝集试验和试管凝集试验均阴性,九江市发生人间布鲁氏菌病散发病例,感染来源和传播因素难以查明。结论在非布鲁氏菌病疫源地单纯依靠现场流行病学调查和血清学检测来调查感染来源和传播的危险因素有局限,建议利用布鲁氏菌病菌株基因库,开展基因序列测定和同源性比对,有助于查明感染来源。
Objective To investigate the risk factors of origin and transmission of brucellosis in Jiujiang City. Methods The epidemiological survey and serological test were used to investigate. Results A total of 7 samples of family members were collected, 5 intimate contact samples and 1 suspicious animal specimens were collected. The tiger red plate agglutination test and tube agglutination test were negative. The incidence of human brucellosis, source of infection and transmission factors Difficult to find. Conclusion There is a limited risk factor for investigating the origin and spread of infection in non-Brucellosis based on field epidemiological and serological tests only. It is suggested to use the gene bank of Brucella spp. Homology comparison helps to identify the source of infection.
