Abstract
BACKGROUND: Symptomatic and asymptomatic bacteriuria (ASB) is common in pregnant women. Pregnancy enhances the progression from ASB to symptomatic bacteriuria, which if left untreated, could lead to acute pyelonephritis and other adverse outcomes such as prematurity, postpartum, hypertensive disease, anaemia, UTIs and higher foetal mortality rates. AIM: To identify the prevalence of ASB, the most common causative microorganisms and the antibacterial susceptibilities of the isolated microorganisms at a tertiary care centre at Kanpur, India. MATERIALS AND METHODS: A total number of 300 asymptomatic pregnant women were screened for ASB by urine culture by using a semi quantitative culture method. RESULTS: In this study, significant bacteriuria was found in only 22 cases (7.3%). Growth of contaminants was seen in 40 cases (13.3%). Among cases which showed positive cultures, 48.9% were primigravidae and 51.1% were multigravidae. Highest incidence was reported in age group of 21-30 years. The predominant organisms which were isolated were Escherichia coli, followed by Klebsiella pneumoniae, Enterococcus faecalis, Staphylococcus aureus and Proteus mirabilis. Escherichia coli, the most common isolate, was found to be only 61% and 70% sensitive to ampicillin and amoxicillin + clavulanate, respectively. Sensitivity to ceftriaxone and ciprofloxacin was 95%, and sensitivity to amikacin was 99%. Hundred percent sensitivity was found for the broad spectrum pencillins, imipenem, and meropenem. Klebsiella pneumoniae, the second most frequent organism which was grown on culture, was only 11% sensitive to ampicillin, while sensitivity to amoxicillin + clavulanate and cefuroxime was 86%. 100% sensitivity was found for cefepime, ceftriaxone, ciprofloxacin, imipenem and meropenem. CONCLUSION: Routine urine culture test should be carried out for all antenatal women, to detect asymptomatic bacteriuria, and every positive case should be treated with appropriate antibiotic therapy, to prevent any obstetric complication which is associated with pregnancy.
