Epidemiological Characteristics, Clinical Presentation, and Risk Factors Associated With Esbl Producing Uropathogens in Urinary Tract Infections at a Tertiary Care Centre
Abstract
Background: Urinary tract infections (UTIs) are common bacterial infections with variable epidemiological patterns, clinical presentations, and bacterial etiologies. Understanding these patterns is essential for accurate diagnosis and appropriate antimicrobial therapy.
Aim: To evaluate the epidemiological characteristics, clinical presentation, and risk factors associated with ESBL-producing uropathogens in patients with suspected UTIs.
Materials and Methods: A total of 400 urine samples were collected from patients with suspected UTIs. Samples were processed using standard microbiological techniques for bacterial isolation and identification. Demographic details, clinical manifestations, and relevant risk factors were documented. Antimicrobial susceptibility testing was performed using the Kirby–Bauer disk diffusion method.
Results: Of 400 urine samples, 304 (76.0%) showed significant bacterial growth, while 96 (24.0%) showed no significant growth. Females constituted 296 (74.0%) patients, and males accounted for 104 (26.0%). The predominant age group was 21–40 years (210; 52.5%). Most patients were outpatients (248; 62.0%), while 152 (38.0%) were hospitalized. Dysuria was the most common symptom (314; 78.5%), followed by increased urinary frequency or urgency (297; 74.2%), suprapubic pain (168; 42.0%), and fever (117; 29.2%). Among culture-positive samples, Enterobacteriaceae accounted for 258 (84.8%) isolates. Escherichia coli predominated (157; 60.9%), followed by Klebsiella pneumoniae (70; 27.1%), Proteus species (21; 8.1%), and Enterobacter species (10; 3.9%). Other isolates included Staphylococcus, Pseudomonas, and Enterococcus species.
Conclusion: Culture positivity was high, particularly among females and patients aged 21–40 years. Dysuria was the leading symptom, and E. coli was the predominant uropathogen. Routine urine culture, susceptibility testing, and local surveillance are essential for guiding appropriate treatment and antimicrobial stewardship.
