Early-onset neonatal group B streptococcal septicaemia in siblings

At each of two consecutive deliveries, a woman gave birth to a baby that developed early-onset group B streptococcal (GBS) septicaemia. A low titre of serum antibodies to the type of the infecting GBS and persistence of the organism in the mother were demonstrated. This case confirms that mothers of GBS infected infants are at high risk of their future babies being similarly infected.
