Abstract

Introduction: Urinary tract infection (UTI), being one of the most common infections, regular surveillance of the changing trends in its bacteriological profile is mandatory. The present study aims at finding the prevalence of UTI and distribution of bacterial agents in different demographic groups of patients over a period of one year from May 2016- April 2017 in a tertiary care centre which caters to the rural population of Palakkad, Kerala. An attempt was also made to find out the differences in the antibiotic resistance pattern among inpatients and out patients.
Materials and Method: In a prospective study, we categorized and analyzed all the urine culture samples, bacterial isolates and their resistance rate based on age, sex and hospital status of the patients.
Results: Total number of urine samples processed is 3772 of which 1265(33.5%) are culture positive. Highest rate of UTI is seen in elderly females (49.7%) followed by elderly males (39.1%), with least from paediatric patients. E.coli, Klebsiella and Enterococci are the three most common isolates from all different categories of patients and constituted ~ 75% of total. Emergence of non-fermenter Gram negative bacilli and Gram positive cocci like Enterococci and Staphylococci as major causative agents is noted in men, especially in adult men.
Conclusion: Similar to several other studies, rate of infection and resistance is more in elderly. Even though the most common isolate is E.coli, its percentage varies in different groups of patients.
