Methodology
Cord blood from neonates born to one hundred and twelve (112) pregnant
women whose cervical samples were positive for CT at first ANC visit
were screened by Polymerase Chain Reaction (PCR) for CT infection.
Transplacental transmission of CT was considered when CT DNA
type-specific agreement was observed between the samples of maternal
cervical specimen and the corresponding neonatal cord blood. A neonate
who did not survive at birth at > 28weeks gestation
or 1000g birthweight is considered stillbirth.
