Abstract:

Vaginal carriage of Group B Streptococcus (GBS) is a maternal and child health issue. Our objective was to determine the prevalence of GBS carriage; identify the factors associated with this carriage and determine the antibiotic sensitivity of the isolated strains. We conducted a cross-sectional and prospective study in rural Senegal (in the health district of Sokone). Socio-demographic, clinical and gynaeco-obstetrical data were collected. Vaginal swabs were taken by the midwives on specific settings in order to test for GBS and other High Risk Vaginal Bacteria (HRVB). Antibiotic susceptibility testing was done according to the recommendations of the CA SFM/EUCAST 2020. In total, 100 pregnant women were targeted and 97 pregnant women were included. Their age ranged from 18 to 40 years with 64.9% (63/97) of participants belonging to the20 - 30 age group. The overall prevalence of Group B Streptococcus carriage was 15.5% (15/97). However, the proportion of women with at least one high risk infectious bacteria was 29.89% (29/97). No statistically significant differences were found between GBS carriage and the potential factors studied. However, the study also looked for the presence of other high-risk bacteria and coinfections were indeed found between GBS and
