Asymptomatic Bacteriuria among Antenatal clients in a Secondary Facility in Southwestern Nigeria

Abstract

Context: Asymptomatic bacteriuria (ASB) is the presence of bacteria in the properly collected urine of a patient that has no signs or
symptoms of a urinary tract infection (UTI). If diagnosed early, UTI and its grave consequences can be prevented in pregnant women.

Aims: The goal was to ascertain the prevalence of ASB in pregnant women attending antenatal clinic.

Subjects and Methods: The study was a cross‑sectional descriptive study. Data were collected using the proforma. Clean catch urine  samples were taken and sent for microscopy, culture, and sensitivity. The data were analyzed by statistical package for social sciences (SPSS) version 23.

Results: A total of 42 women had ASB on urine culture, giving a prevalence of 30.4%. The most common organism cultured was Escherichia  coli (21[50%]) and most of the organisms isolated were sensitive to nitrofurantoin (88.3%).

Conclusions: This study found that the prevalence of ASB among antenatal clients was 30.4%. The dominant organism was found to be E. coli. Majority of the organisms were sensitive to nitrofurantoin (88.3%), cefuroxime (78.6%), ceftazidime (78.6%), and ceftriaxone (71.4%). We found a positive association between the density/number of urinary pus cells of the participants and the occurrence of ASB.
