Trichomonas tenax

Trichomonas tenax (/trɪˈkɒmənəs tɪˈnæks/) is a species of parasite that primarily inhabits the human oral cavity. It is one of the species of the genus Trichomonas, which is part of the family Trichomonadidae.

Etymology

The name Trichomonas tenax is derived from the Greek words "trichos" meaning hair and "monas" meaning unit, referring to the hair-like flagella that the organism uses for movement. The species name "tenax" is Latin for "tenacious", referring to the organism's ability to adhere to surfaces in the oral cavity.

Description

Trichomonas tenax is a protozoan parasite, characterized by its pear-shaped body and four anterior flagella. It is primarily found in the human oral cavity, particularly in individuals with poor oral hygiene or periodontal disease. It is not typically associated with systemic disease, but can cause oral infections in immunocompromised individuals.
