Prevelance and Age Wise Distribution of Bacterial Pathogens in Patients with Urinary Tract Infection

Abstract

Background & Objectives: One of the most common bacterial diseases are urinary tract infections (UTIs), in which the urinary system becomes inflamed due to an abnormal bacterial growth. Annually, there are over 150 million cases of UTIs recorded. Escherichia coli accounts for 80-90 % of infections and the rest are caused by Klebsiella Pneumoniae, Pseudomonas aeruginosa, Proteus mirabilis and Streptococcus.

Methods: Frequency of uropathogens was determined in Ayub Teaching Hospital from December 2021 to March 2022. The midstream urine specimens were collected and inoculated on Cysteine Lactose Electrolyte Deficient agar and blood agar and incubated aerobically at 37 °C for 18-24 hrs.

Results: Out of 1088 samples 441 (40 %) showed growth on culture medium. A higher frequency of Urinary tract infection was observed in females found as 369 (83 %) as compared to males as 72 (16 %). Frequency of Escherichia coli in Urinary tract infection was 355 (80 %) found to be highest as 82 % in females and 17 % in males. Klebsiella found to be the second most frequent bacteria in Urinary tract infection and its frequency was 9 % in females and 1.8 % in males followed by Staphylococcus found as 4 % in females and 0.9 % in males. Pseudomonas aeruginosa & Morganella morganii appeared only in females & frequency was 0.9% and 2 %) respectively.

Conclusion: Maximum frequency of Urinary tract infection observed in age group of 21 to 40 years in both male and females.
