ABSTRACT

Introduction: ASB during pregnancy relates to the physiologic and anatomic changes in the urinary tract. The prevalence of ABS in pregnant women is estimated to be approximately 1.9–15%. Objectives: To determine the frequency of asymptomatic bacteriuria and its causative organisms in pregnant women. Materials & Methods: A total of 191 pregnant women with gestational age >24 weeks, 16 to 40 years of age were included. Patients with genital tract trauma and antibiotic therapy taken within two weeks were excluded. Then clean-catch midstream urine was collected from each woman into a sterile universal container. Samples were cultured on dried plates of blood agar and cysteine lactose electrolyte deficient agar (CLED), using a calibrated drop delivering 0.002ml of urine. Plates were incubated aerobically of 37°C overnight. Colony counts yielding bacterial growth of 105/ml or more of pure isolates were regarded as significant for bacteriuria. Also the causative organism as described in operational definitions was noted by the researcher herself. Results: Age range in this study was from 16 to 40 years with mean age of 28.68 ± 3.86 years. Majority of the patients 108 (56.54%) were between 16 to 30 years of age. Mean parity was 3.15 ± 0.98. In our study, frequency of asymptomatic bacteriuria in pregnant women was found in 29 (15.18%) patients (Figure III). Escherichia coli is the most predominant organism (34.48%) followed by Staphylococcus aureus (31.03%), klebsiella species (13.79%), candida albicans (13.79%) and proteus species (6.90%). Conclusion: This study concluded that frequency of asymptomatic bacteriuria in pregnant women was 15.18% with Escherichia coli being the most common causative organism.
