title: Asymptomatic bacteriuria among an obstetric population in Ibadan.
abstract: BACKGROUND
  Asymptomatic bacteriuria in pregnancy is the major risk factor for symptomatic urinary tract infection during pregnancy. Screening and identification of bacteriuria during pregnancy have been recommended.
  
  
  OBJECTIVE
  To determine the prevalence and pattern of asymptomatic bacteriuria associated with pregnancy.
  
  
  METHODS
  The study was a descriptive, cross sectional survey of pattern of asymptomatic bacteriuria among consecutive patients presenting for the first antenatal visit at a University College Hospital, during a period of two months. Relevant information obtained from all the patients recruited for the study included age, parity, educational level, gestational age and occupation of participant. Haemoglobin electrophoresis patterns were also retrieved and recorded. Main outcome measures were prevalence of asymptomatic bacteriuria, bacterial isolates and their antibiotic sensitivities.
  
  
  RESULTS
  There were 205 eligible participants with a mean age of 30.6 ± 4.3 years and a mean gestational age at booking of 20.9 ±7.0 weeks. The prevalence of asymptomatic bacteriuria was 22(10.7%). The isolated pathogens were predominantly coliforms (Klebsiella and E. coli) accounting for 45.5% and Staphylococcus saprophyticus (27.3%). Only gentamycin, nitrofurantoin and ofloxacin demonstrated high efficacy against these uropathogens with antibiotic sensitivity rates of 72.7%-81.8%.
  
  
  CONCLUSIONS
  Prevalence of asymptomatic bacteriuria in this centre is relatively high. This underscores the need for routine screening of pregnant women for bacteriuria.
