CHARACTERISTICS: Trichomonas vaginalis is a parasitic protozoan flagellate, and organisms vary in size but are usually around 10 μm in length and 7 μm in width(1,2). It usually has an oval or pear-like shape, but can assume an amoeboid form when attached to vaginal epithelial cells.

Which are characteristics of Trichomonas species?
CHARACTERISTICS: Trichomonas vaginalis is a parasitic protozoan flagellate, and organisms vary in size but are usually around 10 μm in length and 7 μm in width(1,2). It usually has an oval or pear-like shape, but can assume an amoeboid form when attached to vaginal epithelial cells.
What are factors that affect the acquisition of the different Trichomonads?
Risk Factors for Acquiring Trichomoniasis: People with more sexual partners are more likely to become infected. Older women may be more likely than younger women to be infected. Black women may be more likely to be infected. Other risk factors for infection may include limited education and low socioeconomic status.
Why is trichomoniasis important?
Trichomoniasis is an extremely common infection worldwide and is associated with important public health problems, including amplification of HIV transmission.
What causes trichomoniasis?
Trichomoniasis is caused by a one-celled protozoan, a type of tiny parasite that travels between people during sexual intercourse. The incubation period between exposure and infection is unknown, but it’s thought to range from four to 28 days.
What is the morphology of trichomoniasis?
Morphology. Trichomonas is around 10 µm in length and is normally pear-shaped. It has four flagella at its anterior end, distinguishing itself from closely related organisms that have different numbers of anterior flagella. At the base of these flagella are the parabasal bodies, kinetosomes accompanied by Golgi stacks.
What is the morphology of Trichomonas hominis?
The shape is pyriform and has an axostyle which runs from the nucleus down the centre of the body and extends from the end of the body and undulating membrane which extends the entire length of the body and projects from the body like a free flagellum. It has 4 free flagella and a single nucleus at the anterior end.
Who is most at risk for trich?
Trichomoniasis is more common in women than men. It affects more than 2 million women ages 14 to 49 in the United States. Trichomoniasis affects more African-American women than white and Hispanic women. The risk for African-American women goes up with age and lifetime number of sex partners.
What are the complications of trichomoniasis?
What are the complications of trichomoniasis? Trichomoniasis can increase the risk of getting or spreading other sexually transmitted infections. For example, trichomoniasis can cause genital inflammation that makes it easier to get infected with HIV, or to pass the HIV virus on to a sex partner.
Is trichomoniasis rare for men?
Trichomonas vaginalis is a rare finding in urine cytology specimens, especially those from men; only 2 case reports have been described in the literature.
What is the prevention of trichomoniasis?
Like any sexually transmitted infection (STI), the best way to prevent trichomoniasis is to have safe sex. This means always using a condom.
How do males get rid of trich?
Trichomoniasis is unlikely to go away without treatment, but it can be effectively treated with antibiotics. Most men and women are treated with an antibiotic called metronidazole, which is usually taken twice a day for 5 to 7 days.
What is the Order of Trichomonadida?
Trichomonadida is an order of anaerobic protists, included with the parabasalids. Members of this order are referred to as trichomonads. Some organisms in this order include: Trichomonas vaginalis, an organism living inside the vagina of humans.
What is the shape of trichomonad?
Trichomonad. The genus Trichomonas is a common parasite in the digestive system of many animals. Trichomonas cells are pear-shaped and may have four flagella anteriorly and a fifth bordering the undulating membrane. A mouth and a basal rod (costa) are found along the membrane; an axostyle, a stiff rod of cytoplasm used for support,…
What type of protozoa is trichomonad?
trichomonad, any protozoan of the zooflagellate order Trichomonadida. Trichomonads have three to six flagella, and one commonly trails or borders an undulating membrane. Most trichomonads inhabit the digestive systems of animals.
