Infected breast milk associated with late-onset and recurrent group B streptococcal infection in neonatal twins: a genetic analysis.

Asymptomatic excretion of group B streptococcus (GBS) in breast milk may be an underrecognized cause of neonatal and recurrent infection. We report the case of late-onset and recurrent infection in newborn twins resulting from ingestion of maternal breast milk infected with GBS. Genetic analysis of isolates is equally presented.
