– the organism is sexually transmitted and rarely leaves its host.

Vaginal exam of women infected shows an erythematous, "strawberry" cervix.
Produces a green, foul-smelling vaginal discharge. (frothy discharge)
_Diagnosis is made via laboratory testing that may include
Visualization of pear-shaped flagellated trichomonads on wet mount
motile trophozoites (classically called "corkscrew" motility) due to flagellated movement.
Positive culture
Positive nucleic acid amplification test
Rapid antigen or DNA hybridization probe test
