Maternal Cervical sample
Maternal cervical samples were obtained from pregnant women on their
first ANC visit, when they were recruited and their epidemiological data
were obtained (10). The cervical samples were obtained using a
cytopathological brush for sampling of the cervix. The samples were
inoculated into TE solution (Tris HCl, pH 7.5 – 10 mM; EDTA, 1 mM), and
stored at -20°C, until the deoxyribonucleic acid (DNA) for CT were
extracted.
