Samples (1,318) of enterotoxigenic Escherichia coli (ETEC) isolated in 1994-1995 from children with diarrhea from Nepal, Indonesia, Peru, and Thailand were examined for colonization factor antigen (CFA) and coli surface (CS) antigens. Fifty-five percent of 361 heat-labile and heat-stable (LT-ST), 14% of 620 LT-only, and 48% of 337 ST-only ETEC had CFA/CS antigens. LT-ST ETEC strains were predominantly in the CFA II group, and ST only strains were in the CFA IV group. Additional studies are needed to identify ETEC strains that do not have CFA/CS antigens.
1994年至1995年期间,从尼泊尔、印度尼西亚、秘鲁和泰国腹泻儿童中分离出1318份产肠毒素大肠杆菌(ETEC)样本,检测其定植因子抗原(CFA)和菌体表面(CS)抗原。361份不耐热和耐热(LT-ST)ETEC中,55%有CFA/CS抗原;620份仅不耐热(LT)ETEC中,14%有该抗原;337份仅耐热(ST)ETEC中,48%有该抗原。LT-ST ETEC菌株主要属于CFA II组,仅ST菌株属于CFA IV组。需要进一步研究以鉴定无CFA/CS抗原的ETEC菌株。
