title: Intrauterine infections with group B beta-haemolytic streptococci.
abstract: The case records of 15 infants with intrauterine infections due to group B beta-haemolytic streptococci were traced from the records of two geographically separate centres over a 4-year period (1979-1982). Six infants were stillborn and the other nine died within the first 6 h. All the infants weighed less than 1000 g and were less than 28 weeks gestation. Placental examination in 14 of the 15 infants showed the presence of chorioamnionitis and funisitis. The infants also showed evidence of pneumonitis. Four infants had evidence of otitis media, two had evidence of an early meningitis. A history of antepartum bleeding was present in six infants and abundant retroplacental clot was noted in four of them. The membranes had been ruptured for greater than 24 h in only three infants. In six of the infants the membranes were intact at the time of delivery. A history of intact membranes at the time of delivery does not exclude a diagnosis of an intrauterine infection with this organism, and this series of infants highlights the importance of routine bacteriologic studies of all perinatal deaths.
