摘要
目的 探究引起细菌性食源性疾病暴发的病原学原因,了解气单胞菌污染食品引起聚集性事件的特征,为类似事件的调查处置提供参考.方法 采集本起疫情患者肛拭子、食品留样、食品加工工具涂抹样,参照《食品卫生微生物学检验》《全国临床检验操作规程》(第四版)进行检验.结果 在小黄鱼食物留样和两名患者肛拭子中,检出温和气单胞菌.在一份厨房用具涂抹液和其中一名患者肛拭子中,检出嗜水气单孢菌.结论 这是一起罕见的混合性气单胞菌引起的食源性疾病暴发事件,提示我们在肠道感染性腹泻的诊治过程中,除了考虑常见肠道致病菌外,气单胞菌等罕见致病菌也不容忽视,以免给临床诊断和治疗带来困扰.
Abstract
Objective To explore the pathogenic factors causing outbreaks of bacterial foodborne diseases.Methods Collecting anal swabs,food retention samples,and food processing tool application samples from patients affected by this epidemic,refer to"Microbiological Testing of Food Hygiene"(GB/T 4789.4-2016、GB/T 4789.5-2012、GB/T 4789.6-2016,GB/T 4789.7-2013,GB/T 4789.10-2016)and"National Clinical Testing Operating Procedures"(Fourth Edition).Results Aeromonas sobria was detected in food samples from little yellow croaker and anal swabs from two patients.Aeromonas hydrophila was detected in a kitchen appliance application and one patient's anal swab.Conclusion This was a rare outbreak of foodborne disease caused by mixed Aeromonas,In the diagnosis and treatment of intestinal infectious diarrhea,in addition to considering common intestinal pathogenic bacteria,rare pathogenic bacteria such as Aeromonas should not be ignored to avoid clinical diagnosis and treatment difficulties.
