Trichomonas vaginalis is a protozoan parasite of the urogenital tract in men and women and causes a sexually transmitted disease, trichomoniasis, in about half of infected women. Infections are associated with pelvic inflammatory disease, adverse pregnancy outcomes, infertility, an increased incidence of aggressive prostate cancers, and an increase in HIV-1 transmission. Learn more in the article by Conrad et al. in the January 2013 issue of Trends in Parasitology.

Trichomonas foetus (via)

Trichomonas foetus is a single-celled protozoan that infects the bovine reproductive tract and the intestinal tract of cats. Cows are infected by bulls that harbor the parasite on their foreskin. The resultant infection of cows can result in infertility, pyometra, and embryonic death and abortion. (More)

What you think is bacterial vaginosis, yeast infection, or trichomonas…

What you think is bacterial vaginosis, yeast infection, or trichomonas… may be “only” a spider mite infestation, or a combination of all the above. One symptom, the intense itching, is what makes these vastly different conditions feel like the same. I’ve been there, I’ve done it. So, how can you tell if you have an infection or an infestation?

Trichomonas vaginalis (lat. Trichomonas vaginalis) - a single-celled organism Trichomonas kind. Has a length of 13-18 microns (30-40 microns). Due to the movement of the flagella and undulating (undulating) membrane Trichomonas can actively move to form pseudopodia and penetrate the intercellular spaces.

Urogenital Trichomonas found only in the urogenital organs. In other organs (intestines, stomach, etc.) And outside the human body, they die rapidly as not to form the protective devices are unstable and adverse environmental factors. Particularly detrimental effect on them drying, heating above 45 ° C, direct sunlight, changes in osmotic pressure, dry quickly in the air. Therefore, to detect urogenital Trichomonas in the environment is not possible. Trichomonas lives in the mucous membranes (in these cases it is not called “urogenital”). The presence of Trichomonas in the human body is a historical fact “symbiosis” of microorganisms with higher forms of life.
