摘要:
4-hour in vitro growth curves of a type III group B streptococcus (GBS) and Escherichia coli were examined in sterile term human amniotic fluid specimens. Both bacterial strains proliferated despite ratios of phosphate to elemental zinc in the range reportedly inhibitory for E. coli. After 4 h of incubation, despite comparable inocula, GBS numbers exceeded those of E. coli by 10-fold to 100-fold. The strikingly rapid growth of some GBS strains in amniotic fluid may represent yet another factor responsible for perinatal GBS infection of the human neonate.
