Bacterial Isolates and Drug Susceptibility Patterns of Urinary Tract Infection at Shaheed Monsur Ali Medical College

This cross sectional study was conducted to isolate and identify the common bacterial causes of Urinary Tract Infections (UTIs) from urine by culture. A total 2542 urine samples were collected from clinically suspected UTIs patients. Common causative bacteria of UTI were detected by Gram staining, culture in different media, different biochemical tests. Among 324 (12.75%) had significant bacteriuria and the rate of positive culture was 11.48% (232/2020) for female and 17.62% (92/522) for male. In this study, the predominant bacterial isolates were E. coli 208 (64.20%) followed by Proteus 56 (17.28%). Other predominant bacterial isolates includes Klebsella species 30 (9.26), Pseudomonas 8 (2.47), Stap. saprophyticus 10 (3.09), Staphylococcus aureus 6 (1.85) and Enterococci 6 (1.85). E. coli as the predominant cause of UTI, 82.69% were resistance to Nalidexic and 98.08% sensitive to Amikacin and Imipenem. Proteus was resistant to Co-Trimoxazole in 60.7% and P. aeruginosa were 100% resistance to ceftriaxone. Among the Gram positive organism, Stap. saprophyticus and Staphylococcus aureus were 100% resistant to Nalidexic, Enterococcus were 66.67% resistant to ciprofloxacin and cefixime.
