Sumario: | BACKGROUND: In many parts of the world, Group B Streptococcus (GBS) is a major cause of maternal and neonatal illness and mortality. It has a negative impact on neonatal and pregnancy outcomes. A worrisome problem in Ethiopia is the unknown rate of antibiotic resistance and the risk factors connected to GBS infections. OBJECTIVE: This study was to determine the prevalence, antibiotic susceptibility pattern, and related variables of Group B Streptococcus among pregnant women receiving prenatal treatment conducted at Bule Hora University Teaching Hospital, Southern Ethiopia, between June 1 and August 30, 2022. METHODS: An institutional-based cross-sectional study was conducted among 213 pregnant women attending antenatal care at Bule Hora University Teaching Hospital. Data on sociodemographic and related factors were gathered using structured questionnaires. The study’s participants were selected using the consecutive sampling method. The lower vaginal/rectum area was brushed with a sterile cotton swab to capture the vaginal/rectum swab sample, which was then examined using microbiological techniques. The Kirby-Bauer disc diffusion method was used to assess antibiotic susceptibility in GBS isolates. Logistic regression analysis was performed on the data using SPSS version 26. It was deemed statistically significant when the p-value was 0.05 with a 95% confidence interval (CI). RESULTS: The overall prevalence of GBS was 16.9% (CI: 0.12–0.23). A history of prematurity of the membrane (AOR: 3.35, 95% CI: 1.19–9.45), a history of stillbirth (AOR: 2.88, 95% CI: 1.07–7.71), and preterm delivery history (AOR: 3.41, 95% CI: 1.31–8.89) (p 0.05) were independent predictors of GBS infection. Cefepime had the highest resistance at 58.3%. Most GBS isolates showed high susceptibility to vancomycin (97.2%) and ampicillin (91.7%). Multidrug resistance was 13.9%. CONCLUSION: The prevalence of GBS was considerably high among pregnant women in this study. This finding emphasises the need for routine screening and testing of antimicrobial susceptibility to provide antibiotic prophylaxis and minimise newborn infection and comorbidity. |
