ASB, if it occurs during pregnancy, can cause serious complications both among fetus and pregnant women.Objective: The aim of this study was to determine the prevalence of ASB, its associated factors, and antimicrobial susceptibility profile of bacterial isolates among pregnant women.Methods: A cross-sectional study was conducted from July to September 2019 among 290 pregnant women at Saint Paul’s Hospital Millennium Medical College, Addis Ababa, Ethiopia. Clean-catch midstream urine specimens were collected using sterile containers and cultured on MacConkey agar and sheep blood agar to isolate bacteria. Socio-demographic and obstetric data were collected using a structured questionnaire. Data were analyzed by SPSS version 22. The association between ASB and risk factors was assessed using logistic regressions. A p-value ≤ 0.05 was considered as a cut point to determine the significant association.Results: From 290 study participants, 16.9% with 95 CI [13.1, 21.5] were positive for ASB. The predominant bacteria were Escherichia coli (43%) and Staphylococcus aureus (20%). Majority of E. coli (91.0%) were susceptible to nitrofurantoin and gentamycin; most of them were resistant to amoxicillin (86.4%) and cotrimoxazole (77.7%). The proportion of multi-drug resistance (MDR) isolates was 57.1%. Previous infection with UTI, previous history of catheterization, and natural abortion were significantly associated with ASB.Conclusion: In the study area, ASB is prevalent in the study area indicating the importance of screening of ASB and possible treatment to prevent its consequences.Keywords: asymptomatic bacteriuria, antibiotic susceptibility, pregnant woman, Addis Ababa, Ethiopi
