One hundred and forty patients with symptomatic urinary tract infection were investigated for serotyping and enterotoxin production. constituted 63 per cent of the 119 culture positive cases followed by and serotype O5 was the most prevalent (29.3%) of the typable strains followed by O17 and O25. Out of the 75 strains, 30 (40%) were enterotoxin producers. Four per cent produced both heat-stable enterotoxin and heat-labile enterotoxin, 21.3 per cent produced only heat stable, whereas 13.3 per cent produced only heat labile toxin. serotype O5 was the commonest enterotoxin producer (45.5%), followed by rough strains (52.9%) and untypable strains (30.7%). Other ET producing strains were O1, O25, O55, O57 and O60. The enterotoxin production of the most prevalent serotype O5 possibly contributes as a virulence marker in UTI cases.
对140例有症状的尿路感染患者进行了血清分型和肠毒素产生情况的调查。在119例培养阳性病例中占63%，其次是……血清型O5是可分型菌株中最常见的（29.3%），其次是O17和O25。在75株……菌株中，30株（40%）产生肠毒素。4%的菌株同时产生耐热肠毒素和不耐热肠毒素，21.3%的菌株仅产生耐热肠毒素，而13.3%的菌株仅产生不耐热毒素。血清型O5是最常见的肠毒素产生菌（45.5%），其次是粗糙菌株（52.9%）和不可分型菌株（30.7%）。其他产肠毒素菌株为O1、O25、O55、O57和O60。最常见的血清型O5产生肠毒素可能是尿路感染病例中的一种毒力标志物。
