The tissue destruction has been created by toxins produced by this and other pathogens at the site of infection. This is a ten second clip which loops continuously with one second between plays.
Trichomonads also parasitize the human digestive and reproductive tracts.
That means that an infection in one site will not spread to a different site and be maintained. In simple language, trichomonas from the mouth will not survive in the digestive tract, and vice-versa. The same is true relative to the mouth trichomonad, Trichomonas tenax in relation to Trichomonas vaginalis . The latter is a parasite of male and female reproductive tracts. Although these trichomonads have a very similar appearance under the microscope, the two species may be distinguished since Trichomonas vaginalis is two to three times larger than Trichomonas tenax.
