【摘要】 目的通过一起幼儿园发生食物中毒的病原学分析,为今后防控细菌性食物中毒提供参考。方法对16例患儿进行流行病调查,并采集患儿及密切接触者共17份粪便样本,经亚硒酸盐胱氨酸增菌、挑取可疑菌落接种三糖铁琼脂培养,采用标准诊断血清进行细菌血清分型。结果患儿中发热及腹痛症状占100.00%,腹泻占93.75%。实验室检测显示,17份样本中14份检出血清学型别相同的肠炎沙门菌,阳性检出率为82.35%。结论该起群体性发热、腹泻事件为一起肠炎沙门菌引起的食物中毒事件,加强食品卫生的监管,强化食品安全意识管理,在学校、幼儿园等集体单位建立健全因症因病报告制度是预防沙门菌食物中毒的重要措施。更多还原

【Abstract】 Objective To provide a reference for the prevention and control of bacterial food poisoning in the future through the etiological analysis of a food poisoning in kindergarten. Methods Sixteen children were etiologically investigated,and a total of17 fecal samples were collected from children and their close contacts. Routine bacterial enrichment,isolation and purification were carried out,and serum bacteria were detected by standard diagnostic serum. Results The ratio of fever and abdominal pain in children was 100. 00%,followed by diarrhea( 93. 75%). Laboratory tests showed that Salmonella enteritidis was detected from 14 samples with same serum types in the 17 samples,with positive detection rate of 82. 35%. Conclusion The outbreak of fever and diarrhea is the result of food poisoning caused by Salmonella enteritidis. To strengthen the supervision and management,to improve health and safety awareness,and to set up the disease surveillance system in schools were important to prevent food poisoning incidents by Salmonella enteritidis.更多还原
