Trichomoniasis (trich) is an infectious disease caused by the parasite Trichomonas vaginalis. [2] About 70% of affected people do not have symptoms when infected. [ 2 ] When symptoms occur, they typically begin 5 to 28 days after exposure. [ 1 ]
Trichomonas vaginalis from a vaginal swab. This is a heavy infection; there were probably thousands of trichomonads in the vagina. Alfred Francois Donné (1801–1878) was the first to describe a procedure to diagnose trichomoniasis through "the microscopic observation of motile protozoa in vaginal or cervical secretions" in 1836.
Avian trichomoniasis is principally a disease of young birds. T. gallinae varies greatly in its virulence. The severity of the disease depends on the susceptibility of the bird and on the pathogenic potential of the strain of the parasite. Adult birds that recover from the infection may still carry the parasite, but are resistant to reinfection.
The 5-nitroimidazole drugs (metronidazole and tinidazole) are the mainstay of treatment for infection with Trichomonas vaginalis. Treatment for both the infected patient and the patient's sexual partner is recommended, even if asymptomatic. Therapy other than 5-nitroimidazole drugs is also an option, but cure rates are much lower. [26]
Trichomonas foetus is a parasite that resides in the urogenital tract of cattle and causes bovine trichomoniasis. Trichomoniasis is a sexually transmitted disease that causes infertility in heifers. Most infertility is caused by sudden embryonic death. [9] Various imidazoles have been used to treat infected bulls, but none are safe and effective.

It lacks a cyst form, but many studies have noted a unique form in which Trichomonas appears ovoidal rather than its typical pear-shaped form. In this ovoidal form, all its flagella are retracted in endocytic vacuoles, giving the impression of a cystic form. However, due to the lack of a cystic wall surrounding the organism, many studies ...
Of the three species in the genus Trichomonas, T. tenax is the smallest, measuring only 5-14 μm long and 6-9 μm wide; specimens can be identified by their long axostyles and tails, 4 anterior flagella, and by the recurrent flagellum that raises an undulating membrane which is two thirds the length of the body.
