摘要
目的了解2009～2014年珠海市腹泻儿童感染沙门菌的流行病学特征。方法对2009～2014年珠海市妇幼保健院4 395例门诊和住院感染性腹泻患儿送检的粪便标本进行沙门菌分离、培养、生化鉴定和血清学分型,并进行统计学分析。结果共检出30种血清型沙门菌546株,分离率为12.42%,小于3岁的婴幼儿沙门菌阳性病例占93.22%,男女患儿分离率差异无统计学意义（χ2=0.572,P〉0.05）。6、7月是沙门菌感染的高峰时期,分离率分别为16.40%和16.09%。鼠伤寒沙门菌（50.92%）、肠炎沙门菌（13.55%）和斯坦利沙门菌（10.26%）为沙门菌优势血清型。结论沙门菌是珠海地区儿童感染性腹泻的主要病原菌,血清型以鼠伤寒沙门菌为主,其感染与年龄和气候密切相关。
Objective To investigate epidemiological characteristics of Salmonella infection in children with infectious diarrhea in Zhuhai City from 2009 to 2014 .Methods Isolation ,culturing ,biochemical identification and serotyping of Salmonella were carried out in strains isolated from stool specimens of 4 395 children with infectious diarrhea in inpatient and outpatient settings in Zhuhai Municipal Maternal and Child Healthcare Hospital from 2009 to 2014 ,and data were statistically analysed .Results A total of 546 strains of Salmonella was isolated（the overall isolation rate was 12 .42% ） and 30 serotypes were identified .Among children with Salmonella infection ,those under 3 years old accounted for 93 .22% .There was no statistically significant difference of isolation rate between male and female children with infectious diarrhea（P〈0 .05） .June and July were peak period of Salmonella infection ,and the isolation rate was 16 .40% and 16 .09% respectively .Isolates of Salmonella typhimurium ,Salmonella enteritidis and Salmonella stanley account for 50 .92% ,13 .55% and 10 .26% respectively ,which were dominant serotypes .Conclusion Salmonella is the main pathogenic bacteria in children with infectious diarrhea in Zhuhai area ,and Salmonella typhimurium is the main serotype .The infec‐tion of Salmonella might be correlated with children′s age and climate change .
