A retrospective study on the prevalence of urinary tract infections in a tertiary care hospital in Sangareddy district of South India
Keywords:Antimicrobial resistance, Bacteriuria, Prevalence, Urinary tract infections, Uropathogens
Background: Urinary tract infections (UTI) affect the portion of the urinary tract including kidneys, ureters, bladder, and urethra, and are among the commonly acquired nosocomial infections. Diagnosis based on the culture and sensitivity profile of the organism is highly beneficial for appropriate antimicrobial therapy of the individual.
Methods: A retrospective study of culture isolates obtained from urine samples from different departments of a tertiary care hospital was performed in the period January 2018 to March 2020 in the district of Sangareddy, Telangana, India.
Results: A total 204 samples of 1886 exhibited significant growth of organisms i.e., ≥105 colony-forming units of bacteria per millilitre (CFU mL-1). The most common pathogen isolated was Escherichia coli (47.05%), followed by Klebsiella pneumoniae (15.68%), Staphylococcus aureus (10.78%), Pseudomonas aeruginosa (10.78%), Enterobacter spp. (7.84%) and, Candida albicans (7.84%). The presence of Gram-negative organisms was found to be more than Gram-positive organisms among the samples cultured. Resistance was found to be more towards Amoxicillin (57.14%), followed by oxacillin (34%), cefotaxime (23.62%), clarithromycin (12.08%), erythromycin (12.08%), azithromycin (9.34%), linezolid (3.84%) and vancomycin (2.19%).
Conclusions: Increasing levels of antimicrobial resistance by uropathogens emphasize the importance of therapy based on the culture and sensitivity of the organisms. Many uropathogens exhibit multi-drugs resistance. Regular surveillance and monitoring are useful in controlling the increasing resistance.
