Abstract: s Urinary tract infection (UTI) is the second most common infection in community practice. It defines as to presence of bacteria in urinary tract, urinary bladder, urine collecting tubes and kidney. UTI causing organisms are mostly human intestinal commensals. These organisms showed virulent behaviors upon transmission to clinically significant biological sites. These organisms includes, Gram Negative Bacilli such as E. coli, Klebsiella pneumoniae, Citrobacter species, Acinetobacter species, Enterobacter species, pseudomonas aeruginosa, proteus species in the Gram Positive coccus include Staphylococcus aureus, staphylococcus saprophyticus, Staphylococcus epidermidis and Enterococcus faecalis and fungi like Candida albicans. Out of these, E coli is the most common organism causing UTI. Serotypes of E.coli consistently associated with UTI are designated as Uropathogenic E. coli or UPEC.
