Investigation of Uropathological Bacterial Profile and Antibiotic Susceptibility Patterns Among Pregnant Women in Rawalpindi and Islamabad: A Comprehensive Analysis

Abstract

Background: Urinary tract infections (UTIs) represent a significant health concern for pregnant women, potentially leading to adverse outcomes for both mother and child. The anatomical and physiological changes during pregnancy increase the risk of UTIs, making the study of their bacteriological profile and antibiotic susceptibility patterns especially pertinent. Objective: This study aimed to assess the bacteriological profile and antibiotic susceptibility patterns of UTIs among pregnant women in Rawalpindi and Islamabad, to identify the most prevalent pathogens and their resistance to commonly used antibiotics. Methods: A cross-sectional study was conducted on 165 early morning mid-stream urine samples collected from pregnant women attending the Railway General Hospital, Rawalpindi, over four months. Samples were analyzed for UTI-causing organisms using Cysteine Lactose Electrolyte Deficient (CLED) medium, MacConkey agar, and blood agar plates. Gram staining and biochemical tests were utilized for bacterial identification, while the Kirby-Bauer disk diffusion method determined antibiotic susceptibility. Statistical analysis was performed using SPSS version 25. Results: The study population predominantly consisted of residents from Rawalpindi (94.5%). The highest incidence of UTIs was observed in the age group of 31-36 years (34.5%). Staphylococcus aureus (28%) and Pseudomonas aeruginosa (30%) were the most prevalent pathogens. High resistance rates were noted against ampicillin and azithromycin among gram-positive isolates, whereas gram-negative bacteria showed considerable resistance to ciprofloxacin. However, gentamicin displayed relative effectiveness across various pathogens. Conclusion: The study highlights a significant prevalence of antibiotic-resistant UTIs among pregnant women in the studied regions, with Staphylococcus aureus and Pseudomonas aeruginosa being the dominant pathogens. The findings call for an urgent need to implement effective antibiotic stewardship and screening programs during pregnancy to mitigate the risk of UTIs and their associated complications.
