Frequency Of Uropathogens In Different Gender & Age Groups

Abstract

Background: Urinary tract infections (UTIs) are most common infectious disease worldwide. The objective of this study was to determine the frequency of uropathogens in relation to gender and age in District D.I.Khan. Methods: This cross sectional study was conducted at the Department of Urology, DHQ Teaching Hospital, D.I.Khan from February 2012 to January 2013. All patients whose routine urine examination revealed numerous pus cells on microscopy were included in the study. The midstream urine specimens were collected in sterile containers and were processed for culture. With standard calibrated loop, 1μl of urine was inoculated on Cysteine Lactose Electrolyte Deficient agar and blood agar and incubated aerobically at 370C for 18-24hrs. After the incubation, if the CFU was more than 105, it was considered significant bacteriuria. Age in years was analyzed as mean and range. Gender, age grouping and culture were analyzed as frequency (number) and relative frequency (%). Results: A total number of 44 UTI cases diagnosed on urine culture were included in this study. Out of these cases 10 (22.7%) were males and 34 (77.2%) were females. The mean age was 39 (1-80) years. E. coli was the leading uropathogen 56.82% followed by klebsella spp. 15.90% , Psedumonos spp.6.82% , Staphylococcus aureus 6.82% , Enterococcus spp. 4.55% Candida spp 4.55% , Enterobacter spp 2.27% & Streptococcus spp. 2.27% respectively. Conclusion: The most common uropathogen was E.coli. Higher prevalence of UTIs was observed in female population. The prevalence of UTIs was highest for age group of 21 to 40 years.
