Group b strep may be found in the vagina and rectum of 5 to 35% of pregnant
women.  This causes no harm to the women.  However, among colonized pregnant
women, 40% to 70% of their infants will acquire the identical group b strep
strain either in utero or during delivery.  Among colonized infants, disease
may occur in two to five infants per 1,000 live births.  Neonatal disease with
group b strep causes two different clinical patterns.  Disease that occurs
during the first 5 days of life usually results in sepsis and pneumonia. 
Disease that occurs from 7 days to approximately 5 months usually results in
meningitis and bacteremia.  
It is recommended that all pregnant women be screened for group b strep during
pregnancy.  This is done by culturing the vagina and rectum.  However, this
does not guarantee that infection of the infant will be prevented.
