The effect of cervical group B streptococcus on the conservative management of preterm premature @entity397 was examined in 140 consecutive @entity1 . Upon the @entity1 's admission, we obtained cervical cultures for group B streptococcus, @entity790 , and @entity1047 . @entity1 with and without group B streptococcus were compared. Group B streptococcus @entity1 had earlier @entity397 (30.7 versus 31.6 weeks) and shorter latent periods (76.8 versus 138.5 hours). @entity281 (six of 16 versus 26 of 120) and @entity7288 (four of ten versus three of 94) were significantly more common in group B streptococcus @entity1 . Neonates of mothers positive for group B streptococcus were smaller (1749 +/- 844 versus 2100 +/- 779 g) and more likely to have @entity166 (eight of 16 versus 29 of 120; P less than .01). Control for the presence of @entity9463 , @entity1047 , listeria, or @entity2954 failed to change the significance of these results. The usual policy was to use intrapartum ampicillin prophylaxis in asymptomatic group B streptococcus @entity1 . However, only four of 16 remained asymptomatic and had latent periods long enough for the results of cultures obtained on admission to be available. We conclude that group B streptococcus significantly complicates the conservative management of preterm premature @entity397 and that the effectiveness of intrapartum prophylactic @entity869 may be compromised by awaiting the results of conventional cultures to define colonized @entity1 .
