目的:了解广州海珠地区2002年-2011年人群中沙门菌的血清型分布和感染状况,为沙门菌病的防控和卫生政策的制定提供科学依据。方法:对2002年-2011年采集的486087份人群标本进行沙门菌的分离、生化、噬菌体鉴定及血清型分型鉴定。结果:486087份肛拭标本共检出沙门菌2596株,检出率为0.53%。所检出的沙门菌经血清分型,分别属于15个群和76个血清型;A～F群的菌株为2572株,占99.08%,说明本地区以A～F群血清型为主;德尔卑沙门菌、奥尔巴尼沙门菌、阿贡那沙门菌、肠炎沙门菌、鼠伤寒沙门菌、山夫登堡沙门菌、斯坦利沙门菌等为本地区常见的沙门菌血清型;非A～F群的菌株24株,占0.92%,检出率比2000年以前大大提高,并有增多的趋势;同时检出多例罕见菌型和国内首次检出的菌型。结论:本地区人群中沙门菌的群及血清型众多且分布广,开展沙门菌血清型监测,对该菌引发的疾病和公共卫生事件的防控有着重要指导意义。
Objective: To understand the serotype distribution and infection status of Salmonella in population from 2002 to 2011 in Haizhu district of Guangzhou, and to provide a scientific basis for the prevention and control of Salmonellosis and the formulation of health policy. Methods: The isolation, biochemistry, phage identification and serotyping of 486087 samples from 2002 to 2011 were carried out. Results: A total of 2596 Salmonella strains were detected in 486087 swab samples, the detection rate was 0.53%. Salmonella detected by serological classification, belonging to 15 groups and 76 serotypes; A ~ F group of 2572 strains of strains, accounting for 99.08%, indicating that the region to A to F serotypes dominated; Del Salmonella burglar, Salmonella Albicans, Salmonella gonorrhoeae, Salmonella enteritidis, Salmonella typhimurium, Salmonella scandinavia, Salmonella Stanley and other Salmonella serogroups in this area; non-A to F Of the 24 strains, accounting for 0.92%, the detection rate was greatly increased from 2000, and there is an increasing trend; at the same time, a number of rare cases detected and the first domestic detection of bacteria. Conclusion: The population and serotypes of Salmonella in this population are numerous and widely distributed, and the surveillance of Salmonella serogroups is of great instructive significance for the prevention and control of the disease and public health incidents caused by the bacteria.
