Trichomoniasis is a sexually transmitted infection caused by the parasite Trichomonas vaginalis. It can be diagnosed through a urine test or genital swab.

iollo markers that associate with Trichomoniasis*


Indole, a metabolite produced from tryptophan by gut bacteria, may be reduced in trichomoniasis as a downstream effect of the parasite’s tryptophan consumption, though the relationship is less direct than with tryptophan itself.


Tryptophan metabolism is altered during trichomoniasis infection. The parasite T. vaginalis is unable to synthesize tryptophan and must acquire it from the host, potentially leading to lower circulating tryptophan levels.
