Introduction: Asymptomatic bacteriuria (ASB) in pregnancy is associated with acute pyelonephritis, premature deliveries, low birth weight, still birth, pre-eclampsia, hypertension, anaemia, and postpartum endometritis. Early detection and treatment of this condition reduces the incidence of these complications. Objective: To determine the prevalence, associated bacteria agents and susceptibility, and risk factors of ASB among pregnant women at the University of Benin Teaching Hospital. Materials and Methods: Two hundred and sixty five respondents were selected using systematic sampling method, between November 2011 and October 2012. These subjects provided clean catch midstream urine samples that were cultured, significant bacteriuric isolates were identified through biochemical tests and sensitivity against regular antimicrobial agents carried out. Data were analysed using SPSS version 16. Results: Of the 265 urine samples cultured, 28 (10.6%) had asymptomatic bacteriuria. Isolates were predominantly Escherichia coli (46.4%), Proteus species (14.3%), Enterococcus faecalis (10.7%), and Staphylococcus aureus (10.7%). These organisms were generally susceptible to tested antibiotics at different degrees. Risk factors included maternal age, parity, and level of education of the woman, as well as spouse's level of education. Occupation of the woman and that of the spouse, gestational age, religion, and ethnicity were not risk factors. Conclusion: Prevalence of ASB among pregnant women in University of Benin Teaching Hospital was 10.6%. Age, parity, and levels of education of both the women and the spouses were risk factors. Periodic surveillance of prevalence, etiology and antibiotics susceptibility is recommended.
