A total of 160 strains of Escherichia coli isolated from urine of patients with clinically diagnosed urinary tract infection were included in the study and 50 faecal isolates of E. coli were studied. They were studied for virulence factors, namely mannose-resistant and mannose-sensitive haemagglutination (MRHA, MSHA) and siderophore production.Among 160 urinary isolates of E. coli , 40 (25%) showed MRHA, siderophore production was seen in 156 (97.5%). In 50 faecal isolates, two (4%) were MRHA, four (8%) MSHA and siderophore production in two (4%). The results suggest that MRHA and siderophore production positive strains can be considered as UPEC.
