Trichomoniasis, sometimes referred to as "trich", is a common sexually transmitted disease that affects 7.4 million previously unaffected Americans each year. It is caused by a single-celled protozoan parasite Trichomonas vaginalis. Trichomoniasis is primarily an infection of the genitourinary tract; the urethra is the most common site of infection in men, and the vagina is the most common site of infection in women.

Symptoms

Trichomoniasis, like many other sexually transmitted diseases, often occurs without any symptoms. Men almost never have symptoms, while 20% of women are asymptomatic.

  • When women have symptoms, they usually appear within 5 to 28 days of exposure. The symptoms in women include a heavy, yellow-green or gray vaginal discharge, discomfort during intercourse, unpleasant vaginal odor (possibly fish-like), and painful urination. Irritation and itching of the female genital area, and on rare occasions, lower abdominal pain also can be present. In about two-thirds of infected females, there is edema, inflammation, cell hypertrophy and metaplasia.
  • The symptoms in men, if present, include a thin, whitish discharge from the penis and painful or difficult urination.

Genetic Sequence

A draft sequence of the Trichomoniasis genome was published on January 12, 2007 in the journal Science confirming that the genome has at least 26,000 genes, a similar number to the human genome.[1] In biology the genome of an organism is the whole hereditary information of an organism that is encoded in the DNA (or, for some viruses, RNA). ...
