Early onset of neonatal sepsis due to group A streptococcus.

Neonatal infections by group A beta-hemolytic streptococcus are very rare in the antibiotic era. There are only a few cases in the first 72 hours after birth. The authors describe a case in which it was confirmed that the bacteria responsible, group A beta-hemolytic streptococcus, had grown in the newborn's blood and in the mother's lochia. The transmission mechanisms are also reviewed.
