Trichomonas vaginalis is a protozoan parasite causing trichomoniasis, often asymptomatic in women, especially those with HIV.
A study evaluated a polymerase chain reaction (PCR) method for diagnosing trichomoniasis in HIV-infected women, comparing it to traditional culture methods.
Results indicated that PCR had a higher detection rate (5.02%) than wet mount (0.51%) and culture (3.03%), suggesting PCR is a more sensitive and faster diagnostic tool for this high-risk group.
