This study has been under taken to know the virulence factors associated with E. coli causing Urinary Tract Infection (UTI) in comparison to intestinal commensal E. coli. Out of 600 UTI patients 100 had E. coli isolates which were studied for virulence factors. A total of 100 isolates of E coli from stool samples of apparently healthy individuals were included as controls. All the E. coli isolates from urine and stools were tested for the following 4 virulence factors- Hemolysin production, Haemagglutination, Serum resistance, Cell surface hydrophobicity. Among case hemagglutination (61%) was the most common virulence factor followed by serum resistance (55%), Cell surface hydrophobicity (CSH) (43%), and hemolysis (27%). In hemagglutination cases 39 were MRHA and 22 were MSHA. Only (21%) of the controls showed hemagglutitation. Most of/all the virulence factors were significantly less among controls compared to cases (P value= 0.000). The expression of virulence factors were more in UTI cases than fecal controls. Hemagglutination was the most frequently observed virulence factor followed by Serum resistance, Cell surface hydrophobicity, and Hemolysin.
