In the present study, 55 Escherichia coli strains isolated from clinical cases and apparently healthy human beings were studied for drug resistance patterns and prevalence of R factor. Results of the study revealed that all the isolates were resistant to bacitracin, whereas none was resistant to kanamycin, neomycin, viomycin, nitrofurantoin and nalidoxic acid. Resistance to penicillin, ampicillin, streptomycin, tetracycline, chloramphenicol and compound sulphonamides was found variable. Studies on prevalence of R factors in resistant E. coli isolates revealed a higher percentage of R factors in clinical group (53.8) than apparently healthy group (21.7). The minimum inhibitory concentration (MIC) ranged from 2-400 .mu.g/ml for tetracycline.
