条件致病菌所致腹泻的病原学分析

Pathogenic analysis of diarrhea caused by opportunistic pathogens

目的条件致病菌所致腹泻的病原学分析。方法对近三年来临床粪便培养标本分离的有氧条件致病菌共336株进行菌种分布的分析和对三种临床腹泻类型进行菌种分布的比较。结果引致腹泻的条件致病菌中金黄色葡萄球菌占11．01％，肠杆菌料占56．83％，假单胞菌属占15．19％，弧菌科的气单胞菌属占9．53％，耶尔森氏菌占1．76％，真菌占5．65％。结论条件致病菌所致腹泻，急性者以金黄色葡萄球菌所致为主，迁延性和慢性者以肠杆菌科为主。应严密监测实验室中无病原菌生长而条件致病菌优势生长的粪便培养情况，及时向临床报告。

To make a pathogenic analysis of the opportunistic pathogens causing diarrhea.Method The distribution of 336 strains of aerobic pathogenic bacteria isolated fromstool culture in the recent three years was analysed and a compative study on distribution of bacteria causing three clinical types of diarrhea was executal. Results The opportunistic pathogens included 11,00% staphylococcus aureus, 56. 83% enteric bacilli, 15. 19% pseudomonas, 9. 53%aeromonas of vibrios, 1. 76% yersinia and 5. 65% fungi. Conclusion Opportunistic pathogenscausing acute diarrhea are mainly ataphylococcus aureus, those causing persisting and chronic diarrhea are mainaly enteric bacilli. The condition of stool culture in the laboratory where no pathogenicbacteria grow but opportunistic pathogens grow predominantly should be put under close supervisionand reported to the clinic without delay.
