Observational study reveals maternal and nosocomial transmission patterns of group B streptococci in neonates, highlighting the importance of strict infection control.

Key Points

To evaluate the epidemiology and transmission routes of group B streptococci between mothers and infants in an obstetric unit and special care baby unit.
Monitored group B streptococci (GBS) acquisition over a one-year period across an obstetric unit and an associated special care baby unit (SCBU).
Screened neonates using rectal and umbilical swabs to identify colonization rates.
Applied serotyping and phage-typing techniques to trace transmission pathways between mothers, infants, and hospital staff.
Maternal transmission occurred rapidly, with 53 of 69 (77%) maternally colonized infants colonized within 24 hours of birth compared to 9 of 38 (35%) who acquired GBS non-maternally.
Non-maternal transmission accounted for 38 of 107 (36%) colonized infants in the obstetric unit compared to only 2 of 23 (9%) in the SCBU.
Typing demonstrated that colonized mother-baby pairs rather than healthcare staff were the primary source of nosocomial GBS, with colonization terminating following hospital discharge.
