Abstract

Introduction: Pregnancy predisposes women to asymptomatic bacteriuria (AB) and screening of pregnant women for AB at the early stage of pregnancy is necessary.

Materials and methods: Clean catch midstream urine from pregnant and non-pregnant women were investigated for AB and UTI by cultural methods using appropriate bacteriological media and standard microbiological procedures.

Results: Out of 210 pregnant women examined for bacteriuria the prevalence rate of AB was 34 (16.9%), the prevalence among 200 non-pregnant women used as a control was 8(4.0%), while the prevalence among 200 symptomatic non-pregnant women was 116(58%). The prevalence of AB by trimester among pregnant women was 6(2.9) in the first trimester, 20(9.5%) in the second trimester, and 8 (3.8%) in the third trimester. By age groups, age 26-30 yrs had a high prevalence of 14(6.9%) among pregnant women, while the prevalence of UTI was high 52(26.0%) among non-pregnant from age 41yrs and above. By educational status, graduates among the pregnant women had a prevalence rate of 21(10.0%), secondary 10(4.8%), and primary 3(1.4%). The symptomatic non-pregnant women, graduates had a prevalence rate of 86(43.0%), secondary 26(13.0%) and primary 2(2.0%). AB and symptomatic bacteriuria were high among subjects living in bedroom flats and self-contained than group houses. The percentage occurrences of bacteria from pregnant and non-pregnant women were: The percentage occurrences of bacteria isolated from asymptomatic pregnant women (AP) were E. coli 16(47.1%), Klebsiella sp. 7(20.6%), Pseudomonas sp. 1(2.9%) and S. aureus 10(29.4%) respectively. The non-pregnant asymptomatic women (AnP) E. coli 8(100%) and the symptomatic non-pregnant women (SnP) E. coli 52(44.8%), Klebsiella sp. 36(31.0%), Proteus sp. 8(6.9%), Pseudomonas sp. 12(10.3%) and S. aureus 8(6.9%) respectively. The overall percentage occurrences of bacteria isolated were E. coli 76(48.1%), Klebsiella sp. 43(27.2%), Staphylococci sp. 18(11.4%), Pseudomonas sp. 12(8.2%) and Proteus sp. 8(5.1%).

Conclusion: AB in pregnancy and UTI are of public health concern that calls for intervention to prevent deleterious complications on mother and fetus that may require hospitalization. There was a risk factor associated with age and trimester of pregnancy.
