Epidemiology and antibiotic sensitivity pattern of asymptomatic bacteriuria during pregnancy: A cross-sectional study

Background: Asymptomatic bacteriuria (ASB) during pregnancy is associated with significant maternal and fetal complications. Continuous monitoring of antibiotic sensitivity pattern of bacterial isolates is required for appropriate management of ASB. Aims: The study aims to assess the prevalence, risk factors, and antibiotic sensitivity profile of ASB during pregnancy. Materials and Methods: A cross-sectional, hospital-based study was conducted in the pregnant women attending Obstetrics and Gynecology Department of a tertiary care hospital. A suitably designed data collection form was used to collect sociodemographic profile, obstetric history, and illnesses suffering from the participants. Urine specimens of the participants were processed for isolation and identification of bacterial species. Kirby–Bauer disc diffusion test was used to screen antibiotic sensitivity of the isolated bacteria. Statistical Analysis: Descriptive statistics were used to represent the sociodemographic data. Chi-square test was used to associate risk factors for the development of ASB during pregnancy. Results: A total of 1332 women were participated in the study. The prevalence of ASB among pregnant women was 86 (6.4%) and Escherichia coli (58; 67.4%) was the most predominant bacteria. Meropenem, cephalosporin's, and gentamycin were shown higher sensitivity in ASB. Advanced age, illiteracy, rural residency, multigravida, multiparity, history of abortion, and medical illnesses were strongly associated to develop ASB during pregnancy. Conclusion: E. coli were the most predominant isolated uropathogen in ASB. The study observed that there is a wide variation in the antibiotic sensitivity pattern of isolated organisms. Hence, there is a need of routine urine culture sensitivity screening in pregnant women for rational use of antibiotics and to reduce the antibiotic resistance.
