Streptococcus agalactiae carriage, serotype distribution and associated antibiogram among pregnant and non-pregnant women in Jos city, Nigeria

Abstract

Background: carriage rate, serotypes, as well as antimicrobial resistance (AMR) of the isolates among pregnant and non-pregnant women in Jos metropolis, Nigeria. Methodology: High vagina and anorectal swab samples were collected from 200 pregnant women and 100 non-pregnant women. Isolates were identified and characterized biochemically and serologically. Epsilometer test was used to determine the antimicrobial susceptibility of isolates. Sociodemographic variables of participants were collated through the structured questionnaire. Results: were Ia (22.2%), II (33.3%), III (33.3%) and IX (11.1%). The highest antimicrobial susceptibility of the isolates was to benzylpenicillin (88.9%), clindamycin (88.9%) and least to ampicillin (66.7%). Conclusion: colonization, low AMR, and varied serotypes. Most of the isolates were susceptible to benzylpenicillin, clindamycin, ampicillin, and erythromycin. The screening of pregnant women during antenatal visits should be encouraged to detect infections and minimize potential transmissions to neonates.
