Epidemiology of group B streptococci colonization and disease in mothers and infants: update of ongoing 10-year Jerusalem study.

A study in 1984 of the colonization rates of Group B beta hemolytic streptococci (GBS) in 257 Jewish and 189 Arab parturient women revealed rates of 5.4 and 1.6% respectively. In 1987, a study of 116 Jewish women noted a rte of 3.5%. GBS colonization rates in the newborns of the three groups were 1.8, 1.3 and 1.1% respectively. No statistically significant differences were noted between any of the maternal or neonatal groups. A review of the period 1982-87 revealed a GBS neonatal sepsis attack rate of 0.2/1,000 live births. These data confirm the persistent low incidence of GBS colonization and disease in the Jerusalem area.
