摘要
目的探讨33起食源性疾病的病原微生物分布情况。方法根据患者临床表现和标本种类,选用相应的选择性培养基,按照《食品卫生微生物学检验》(GB4789-94)和《霍乱防治手册》(部颁)及相关资料进行病原微生物的分离鉴定。结果33起食源性疾病的突发事件中,检测各类标本共745份,检出各类病原微生物63株(检出率8.5%),其中肠道致病菌20株(沙门菌8株、变形杆菌7株、肠致病性大肠埃希菌3株、志贺菌2株),占31.8%;致病性弧菌19株(霍乱弧菌9株、麦氏弧菌4株、沙鱼弧菌3株、拟态弧菌2株、副溶血性弧菌1株),占30.2%;蜡样芽胞杆菌5株,占7.9%;类志贺邻单胞菌5株,占7.9%;金黄色葡萄球菌2株,占3.2%;轮状病毒阳性标本(酶联法检测粪便中轮状病毒抗原)12份,占19.0%。结论在从33起食源性疾病中分离的各类病原微生物中肠道致病菌和致病性弧菌占主要地位。
Objective This analysis was made to explore the distribution of pathogenic microorganisms in 33 cases of foodborne diseases. Methods According to clinic manifestations and species of samples, corresponding selective culture media were chosen, and isolation and identification of pathogenic microorganisms were performed in terms of 'Microbiological testing of food hygiene' (GB4789-94) and 'Manual for prevention of cholera'(issued by the Minister of Health) as well as pertinent data. Results In 33 accidental cases of foodborne diseases, 63 strains of various pathogenic microorganisms from 745 samples tested were found (with a detection rate of 8.5%), of which there were 20 strains of enteropathogenic bacteria (8 saimonella, 7 bacillus proteus, 3 enteropathogenic escherichia coli and 2 Sh.dysenteriae), accounting for 31.8%; 19 strains of pathogenic vibrio (9 bacillus comma, 4 vibrio metschnikovii, 3 vibrio carchariae, 2 vibrio mimicus and 1 vibrio parahaemolyticus), accounting for 30.2%; 5 strains of bacillus cereus, with a rate of 7.9%; 5 strains of plesimonas shigelloides, accounting for 7.9%; 2 strains of staphylococcus aureus, accounting for 3.2%; 12 positive samples of stellavirus (antigens of stellavirus in feces were determined by ELISA), with a rate of 19.0%. Conclusion Enteropathogenic bacteria and pathogenic vibrio hold precedence among various microorganisms isolated from 33 cases of foodborne diseases.
