摘　　要：目的了解和掌握深圳市龙岗区腹泻患者中沙门菌感染状况及菌型分布。方法采集2009-2012年在哨点监测医院(龙岗区人民医院)就诊的腹泻患者粪便标本3 014份,对致病菌进行分离、培养和鉴定,并对阳性菌株进行分子生物学特征分析。结果 3 014份标本共分离到107株沙门菌,阳性率为3.55%,阳性率以10岁以下的年龄组最高;沙门菌的发病率在秋季达高峰,共分离出29种血清型,其中鼠伤寒沙门菌和肠炎沙门菌最多,构成比均占29.7%(各30株)。结论深圳市龙岗区腹泻患者主要以鼠伤寒沙门菌和肠炎沙门菌感染引起的腹泻为主。通过加强对腹泻门诊腹泻患者沙门菌的监测,追踪传播来源,提高暴发流行的预警能力。Objective To understand the situation of Salmonella infection and distribution of various Salmonella serotypes in diarrhea patients in Longgang District, Shenzhen. Methods In total of 3 014 stool samples of the outpatient cases were collected for sep- aration, cultivation and identification of pathogenic bacteria in 2009-2012. The molecular characteristics of the positive strains were analyzed. Results The total positive rate of the Salmonella was 3.55%. The positive rate of 0- group and 10- group was the highest. The high incidence season was autumn and 29 serotypes were isolated. Salmonella typhimurium and Salmonella enteritidis were the main serotypes, both accounting for 29.7% （30 strains each）. Conclusion Diarrhea in Longgang District of Shenzhen is mainly caused by Salmonella typhimurium and Salmonella enteritidis. Strengthening the monitoring of Salmonella and tracking the spread of sources in diarrhea patients will improve the early warning capability on the outbreak.
