Serotyping and transferability of drug resistance in clinical isolates of E. coli.
Forty nine multiple drug resistant strains of E. coli isolated from UTI were serotyped. The pattern was found to be 057 (eight strains); 0109 (four strains); 020, 038, 068, 0106, 0148. Rough (three each). 012, 054, 0101, 0160 (two each) and 02, 032, 046, 053, 060, 065, 090, 091, 0117, 0118, untypable (one each). The resistance pattern of all E. coli were identified and matted with recepient strain in penassay broth and in human urine. In a penassay broth transfer of resistance was demonstrated in 38 strains (77.5%) while in human urine transfer was demonstrated only in 14 strains (28.57%).
