一起由鼠伤寒沙门氏菌引起食物中毒的实验室检测

目的对一起食物中毒的采集样本进行相关微生物学检验,确定引起食物中毒的病原菌,为食物中毒的处理提供科学依据。方法根据流行病学调查及临床表现,选择疑似的病原菌,依据《食品安全国家标准食品微生物检验》,对采集的样品进行病原菌分离与鉴定。结果从采集的2份剩余食物中检出鼠伤寒沙门氏菌,2位患者恢复期血清比急性期血清中的鼠伤寒沙门氏菌抗体水平有4倍以上的增高。结论该次食物中毒由鼠伤寒沙门氏菌污染所致。

Laboratory detection of food poisoning caused by salmonella typhimurium

Objective To confirm the pathogen of food poisoning by doing relevant microbiological examination for the collected samples,and provide scientific basis for treatment of food poisoning.Method Choose suspected pathogens according to epidemiological investigation and clinical manifestations,and do pathogen isolation and identification according to National Food Safety Standards Food Microbiological Examination.Results Salmonella typhimurium were detected from the 2 samples of remaining food.The antibody level of salmonella typhimurium of the 2 patients in convalescence was four times higher than that in acute phase.Conclusions The food poisoning was caused by salmonella typhimurium.
