A loop-mediated isothermal amplification (LAMP) assay was developed to detect the sexuallytransmitted parasite, Trichomonas vaginalis in vaginal swabs. The presence of T. vaginalis was detected from 121 female sex workers attending a social hygiene clinic in Balibago, Angeles City, Pampanga, Philippines using culture, polymerase chain reaction (PCR), and the developed LAMP assay. The high analytical sensitivity of LAMP detected a higher prevalence of T. vaginalis (42.06%) compared to culture (8.26%) and PCR (7.44%). Additionally, this assay did not cross-react with DNAs of other trichomonads that can infect humans such as Trichomonas tenax and Pentatrichomonas hominis as well as the pathogens, Candida albicans and Staphylococcus aureus. The LAMP assay developed had a limit of detection (0.036 ng/μl) lower than that of PCR using the primers TvK3 and TvK7 (0.36 ng/μl). Prevalence of T. vaginalis in female sex workers in this area of the Philippines may be higher than previously estimated. Discordant results of PCR and LAMP may be due to different reactions to different kinds of inhibitors in the vaginal swabs.
