Neonatal sepsis due to vertical transmission from maternal genital tract
High vaginal swabs (HVS) of 1792 expectant mothers were sent for culture at the time of delivery, prior to first vaginal examination. The newborns were followed-up for development of superficial or deep infections. Appropriate cultures of the babies who developed infections were sent. Bacterial growth of predominantly gram-ve organisms was obtained in 1026 (57%) HVS. Infection developed in 48 (27%) babies in 1 st 72 hours of life, of which 28 had deep infection while the rest had superficial infection. Vertical transmission of organisms was documented in 24 (1.3%) mother—baby dyads and the same was 72% in newborns who were at risk of developing sepsis by septicemia scoring, showing a significantly higher incidence of vertical transmission and subsequent sepsis in high risk newborns.
