【摘要】 目的了解我县城区常见蝇类携带病原菌及其耐药状况。方法采用诱蝇笼诱捕法诱捕苍蝇,对常见蝇类携带大肠菌群、细菌菌落数和病原菌及其耐药状况进行检测。结果 6月蝇密度最高,为49.3只/笼,绿蝇占总数的33.0%。常见蝇类体表携带细菌菌落数最高达7.1×107cfu/只,体内携带细菌菌落数最高达2.3×109cfu/只;常见蝇类体表携带大肠菌群数最高达9 882MPN/只,体内携带大肠菌群数最高达12 263MPN/只。未检出致病菌,但检出多种条件致病菌,肠道杆菌菌株对常用抗生素有一定耐药率。结论苍蝇体内外携带大量各种细菌,有传播肠道传染病的风险,应加强环境卫生,消灭"四害"。更多还原

【Abstract】 Objective To understand flies carrying pathogen status and its resistance condition in Ganyu.Method Catching flies with cages and detecting coliform bacteria,bacterial colony and pathogenic bacteria which carried by flies,resistant situation was observation too.Results Flies density was highest in June,it was 49.3 per cage,greenbottle was accounted for 33.0% of the total.There were 7.1×107 bacterial colonies in common flies body surface and 2.3×109 internal.There were 9 882 MPN coliform bacteria in common flies body surface and 12 263 in common flies body.The hathogenic bacteria had not detected out,but conditional pathogenic bacteria existed.There was resistance ratio of enteric bacilli to common antibiotics.Conclusions Flies carried various kinds of bacteria and may spread intestinal disease,so environmental health should be strengthened and eliminated pests too.更多还原
