Abstract

Purpose: Group B Streptococcus (GBS) infection is a major cause of neonatal sepsis. The objective of this study was to estimate the prevalence and risk factors for GBS carriership among parturient women in Jerusalem. Methods: A cross-sectional study of 436 parturient Jewish women at Hadassah-Hebrew University Medical Center, Mount Scopus. The study included patient interview and vagino-rectal swab for culture. Main outcome measures were the prevalence of GBS carriership among study population. Results: Of the 436 participants, 77 had a positive culture for GBS, giving a carrier rate of 17.7%. No differences were found between carriers and non-carriers in age, BMI or parity. Orthodox Jewish women had a significantly higher carrier rate compared with secular Jewish women (20.6% vs. 12.8% respectively), yielding an age, education and BMI adjusted odds ratio (OR) of 1.9 (95% confidence interval (CI): 1.06 - 3.40). Similarly, ritual immersion was associated with increased risk of carrier state with an adjusted OR of 2.01 (95% CI: 1.03 - 3.92, P = 0.039). Conclusions: Our study suggests an association between ritual immersion in the Mikveh and GBS carriership.
