Trichomonads observed under the light microscope in freshly processed clinical samples are rapidly moving circling in in a jerky manner with no clear direction not escaping the microscope field translucent small.

Sexual intercourse Infective Stage Diagnostic Stage Multiplies by longitudinal binary fission Trophozoite in. Transmission Transmission of the parasite from one bird to another occurs in one of three ways. It has cosmopolitan distribution throughout the globe and affects both men and women.

Vaginalis is a monogenetic parasite. The shape of T. Trichomonas vaginalis divides by binary fission and does not appear to have a cyst form.

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. Trichomoniasis is a venereal disease of cattle caused by Tritrichomonas also referred to as Trichomonas fetus a large pear-shaped flagellated protozoan which is an obligate parasite of the bovine reproductive tract. Trichomonas tenax It is a protozoan that during its life cycle presents a form the trophozoite.

The trichomonads multiply rapidly by simple division binary fission but do not form a resistant cyst. Trichomonas has a trophozoite form its pear-shaped form which is most commonly observed and an amoeboid form which appears during host colonization. Trichomonas vaginalis is the parasitic protozoan residing in the urogenital tract causing trichomoniasis which is the leading non-viral sexually transmitted disease.

Trichomonads have a direct life cycle and reproduce by binary fission. Clinical Signs and Diagnosis. The parasite does not appear to have a cyst form and does not survive well in the external environment.

Demonstration and Characterization of Cyst-Like Structures in the Life. This means that it does not present cysts in such a way that its infectious form is also represented by the trophozoite. The disease varies from a mild condition to a rapidly fatal one with death in 418 days post infection.

The natural hosts are human beings where the parasite lives as a colourless pyriform flagellate measuring usually 15 to 18 ц in length and 5 to 15 ц in breadth.

The life cycle of Trichomonas vaginalis is completed in a single host either female or male. Described parasite forms include motile trophozoite and nonmotile pseudocyst stages.

In this ovoidal form all its flagella are retracted in endocytic vacuoles giving the impression of a cystic form. They exist only in trophozoite phase and there is no cystic phase. A single elongated nucleus lies at the round anterior end.

However due to the lack of a cystic wall surrounding the organism. The lesions consist of inflammation and ulceration of the mucosal surface. It has approximate measurements of between 5-15 microns although some have been recorded that have reached up to 20 microns.
