Abstract

Objectives: To have an updated knowledge and periodic monitoring of the most common organisms causing UTI
from time to time.
Materials and Methods: This study was carried out in the Microbiology laboratory of Pathology Department, Khyber
Medical College Peshawar. A total of 95 patients with signs and symptoms of urinary tract infection were recruited for
this study. Exclusion criteria included antibiotic usage within three days and large fluid intake (less than one hour) before
clinic attendance. Clean–catch midstream urine was collected from each patient into sterile broad mouthed container.
Ten ml of urine sample was centrifuged at 2000g for 5 minutes. The supernatant was discarded and a drop of the deposit
was examined microscopically at high magnification for pus cells red blood cells, epithelial cells, cast, and crystal.
Results: A total of 95 patients of UTI attended the Microbiology laboratory. Out of these 58 (61.1%) were female and
37 (38.9%) were male. Escherichia coli was found to be the most predominant organism (isolate) causing UTI in this
study. This was followed by Pseudomonas (7.4%), Citrobacter (3.2%), Staphyllococcus (3.2) and mixed by Escherichia
coli and Pseudomonas (3.2%).
Conclusion: Escherichia coli were the predominant isolates causing UTI with female to male ratio of 2:1
