Abstract

Urinary tract infection is one of the most common infectious diseases in human population. Nowadays UTI has become difficult to treat because of an increasing drug resistance. The main aim of the present study was to determine the bacterial pathogens of UTI and to find out the antibiotic sensitivity pattern of Isolated pathogens. In the present study, totally 201 uropathogenic isolates were isolated from UTI infected patients. Out of 201 uropathogenic isolates, 109 from uncomplicated UTI, 76 from complicated UTI and 16 from asymptomatic bacteriuria. Among the 109 uropathogenic isolates from uncomplicated UTI, 78.9% were E.coli. Out of 76 isolates from complicated UTI, 76.3% were E.coli. 100% uropathogenic E.coli isolates from asymptomatic bacteriuria. Maximum zone of inhibition (38 mm) was recorded while using ciprofloxacin antibiotic against uropathogenic E.coli.

Keywords: Urinary tract infections, antibiotic sentivity, antimicrobial drugs.
