| Abstract: | ![]()
The mechanisms of pathogenicity in EPEC strains were studied in tissue culture. Escherichia coli was isolated as the predominant organism in the primary culture of 1293 (70.54%) diarrhoeal cases. 284 (90.44%) cases from the age group of 1-6 months showed Escherichia coli as the predominant organism. Classical Enteropathogenic Escherichia coli (EPEC) were detected in 311 (24.05%) cases. Among EPEC isolates 277 (89.06%) did not produce either LT or ST. 32 (10.28%) produced LT or ST. 2 strains produced verotoxins belong to serotypes 0:86; K:61, 0.26; K:60, serogroups 0.86:K61 0142:K86, 0:128:K67, 0 126: 71, 0125:K 70, 0119: k69 showed localised adherence and serogroups 0111:K58-055:K59 showed both localised and diffused adherence to HeLa cells. |
