Muhammad Shabbir, Imran Ali, Noor Ul Iman.

Abstract
Objective: To investigate frequency of various urinary tract infections (UTI) pathogens and their antibiotic susceptibility in patients of different age and gender groups at a tertiary care hospital in Peshawar.
Methodology: This descriptive cross-sectional study was carried out at Khyber Teaching Hospital, Peshawar from January 2014 to September 2015. Total of 787 urine cultures were performed using conventional microbiological techniques. Biochemical techniques were used to identify the organisms and antibiotic sensitivity was determined by Kirby-Bauer and Minimum Inhibitory Concentration methods
Results: Out of 787 samples cultured, 458 (58.2%) were positive and were included in study. Age ranged from 1 year to 111 years (mean 41.7). 314 (68.6%) were female and 144 (31.4%) male. UTI was commoner in female (68.6%) than male (31.4%). E. coli was the most common pathogen and accounted for 76.6% of all growths. Up to age 10 years Enterobacter spp., (25%) and between age 41-50 years Morganella spp., (8.3%) were second common pathogens in females. In rest of all age groups Citrobacter spp., were second common pathogens accounting for 10.5% of all positive cultures. Morganella spp., (5.0%), Pseudomonas spp., (3.5%), Enterobacter spp., (1.3%), Klebsiella spp., (1.1%), Staphylococcus aureus (0.9%), Proteus spp., (0.7%) and Streptococcus faecalis (0.4%) were present in less than 13% cases. E. coli was sensitive to Imipenem (98.6%), Meropenem (97.8%), Tazobactam (96.2%), Cefoperazone+sulbactam (93.9%) and Amikacin (92.5%) and was resistant to Nalidixic acid (91.7%) and Ampicillin (90.8%). Citrobacter spp., had sensitivity to Amikacin (93.8%), Meropenem (93.8%) and Imipenem (93.0%) and was absolutely resistant to Ampicillin (100%)
Conclusion: Common uropathogens were E. coli and Citrobacter spp. All gram-negative uropathogens were sensitive to Imipenem, Meropenem, Tazobactam, Cefoperazone+sulbactam and Amikacin. There was high resistance to Penicillin, Cephalosporin, and Fluoroquinolones

Key words: Urinary tract infection, UTI, Escherichia coli, antibiotic resistance.
