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。
A total of 78 strains of toxin-producing Escherichia coli (ETEC) were cultured in 205 cases of feces, with a total detection rate of 38.04%. 107 cases without medication, detected LT / ST 39, ST4, LT32 strains, the detection rate was 70%; 98 cases have been used, the detection rate was 3.06%. Medication can be used to improve the detection rate of ETEC 23 times. LT / ST ETEC is the predominant strain of diarrhea. Dehydration Ⅲ ° accounted for 80.1%, of which LT / ST type accounted for 58.7%, the degree of dehydration and strain type of drug production. In 75 ETECs, 53.6% were positive for CFA, and 7 were ETEC negative in 58 patients. Therefore, CFA was not a specific serum agglutination test, and it was still determined to detect enterotoxins.
