Abstract
Background: Group B Streptococcus (GBS) is a major cause of bacterial infections in the perinatal period, of which colonization prevalence among Northern-Nigerian pregnant women is scarce. We attempted to determine 1) its prevalence, 2) risk factors for GBS colonization and 3) drugs-susceptibility. Methodology: This cross-sectional study involved 185 pregnant women between 35 - 37 weeks of gestation at tertiary health center of Sokoto, Nigeria. Vaginal/rectal swabs were collected, were cultured for GBS and tested for drug-susceptibilities. The study was conducted between December, 2017 and April, 2018. Results: One hundred and eighty five (185) pregnant women participated in this study. GBS vaginal-colonization-rate was 3.8% (7/185). A significance relationship was observed between GBS-colonization and socio-economic class, as 57.10% (4/7) of the GBS positive women were of low-socio economic class (p 0.035). No associations were observed between GBS-colonization and the followings: maternal age, parity, poor obstetric outcome-history. All the 7 GBS positive cultures were sensitive to Clindamycin. One was sensitive to both Clindamycin and Ceftriaxone. None was sensitive to Penicillin. Conclusion: The prevalence of GBS colonization was low in this area. Maternal socio-economic class is found to be a risk of GBS-colonization.
Highlights
IntroductionIt is a major cause of perinatal bacterial infections like amnionitis, bacteraemia, endometritis and urinary tract infections in pregnancy [2]
There was an association between GBS colonization and low socio-economic status of the study participants
There was no association between GBS colonization and maternal age and low parity
Summary
It is a major cause of perinatal bacterial infections like amnionitis, bacteraemia, endometritis and urinary tract infections in pregnancy [2]. Marital status, education and smoking are factors that have been reported to influence the prevalence of GBS colonization [7]. Group B Streptococcus (GBS) is a major cause of bacterial infections in the perinatal period, of which colonization prevalence among Northern-Nigerian pregnant women is scarce. A significance relationship was observed between GBS-colonization and socio-economic class, as 57.10% (4/7) of the GBS positive women were of low-socio economic class (p 0.035). No associations were observed between GBS-colonization and the followings: maternal age, parity, poor obstetric outcome-history. All the 7 GBS positive cultures were sensitive to Clindamycin. Maternal socio-economic class is found to be a risk of GBS-colonization
