摘要
205例粪便培养出产毒素大肠杆菌(ETEC)78株,总检出率为38.04％。107例未用药,检出LT/ST 39株,ST4株、LT32株、检出率70％;98例已用药,检出率为3.06％。用药前来便可提高ETEC检出率23倍。LT/ST ETEC是腹泻流行的主要菌株。脱水Ⅲ°者占80.1％,其中LT/ST型占58.7％,脱水程度与菌株产毒类型有关。75株ETEC中CFA阳性占53.6％,阴性58例中检出ETEC7例,故CFA不是特异血清凝集试验,最后确定仍需检测肠毒素。
78 Enterotoxigenic Escherichia coli (ETEC) strains were isolated from 205 stool specimens. Total detection rate was 38.04%.39LT/ST strains、4 ST strains and 32 LT strains were isolated from 107 cases of non-treatment group, the detection rate was 70%, and that of 98 cases of the treatment group was 3.06%. So collecting specimens before treatment could raised 23 times for the detection rate of ETEC, LT/ST ETEC was the important pathogenic bacteria of the epidemic diarrhea. It was distincted from either eastern or western of our country. The toxigenic type of ETEC was of the geographical difference. The patients of dehydration Ⅲ°took up 80.1%, among them, LT/ST were 58.7%. The degree of dehydration were related to toxigenic type. The positve CFA was 53.6% in 75 ETEC strains. We also detected 7 ETEC strains from 58 cases of the negative CFA. It showed that CFA was not the special coagulation test and examination of the enterotoxin was neceessary.
