From July through to September 2015, we conducted a cross-sectional study at the antenatal care clinic of Kilifi County Hospital, Kenya. The main aim of that study was to describe the prevalence and predictors of curable sexually transmitted infections (STIs) among pregnant women attending to the antenatal care clinic . Women were eligible if they met the following criteria: age 18–45 years, gestation ≥ 14 weeks, resident of the Kilifi Health and Demographic Surveillance area, willingness to undergo free STI and bacterial vaginosis screening procedures, and able and willing to give written informed consent . The current study presents a secondary objective of the above-mentioned study, namely to perform typing of T. vaginalis clinical isolates from this study population.
