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.
The following signs or symptoms may indicate the presence of infection: [9] Irritation or itching of the genital area; inflammation (irritation, redness, and swelling caused by the presence of extra immune cells) of the labia majora, labia minora, or perineal area; vaginal discharge; foul vaginal odor [10] pain/irritation with sexual intercourse
Trichomoniasis is a common STI that is caused by infection with a protozoan parasite called Trichomonas vaginalis. [70] Trichomoniasis affects both women and men, but symptoms are more common in women. [71] Most patients are treated with an antibiotic called metronidazole, which is very effective. [72]
Trichomonas vaginalis, being the species that causes the most complications in humans, is the only fully sequenced Trichomonas species. Through whole-genome shotgun sequencing, the Trichomonas vaginalis genome is estimated to be around 160 Mb long, divided into six chromosomes. However, at least 65% of its genome was found to be redundant.
Treatment: Getting tested regularly after having sex with a new partner or once a year if you’re 25 or younger are important ways to identify and treat STIs before symptoms appear. But if you ...
Diagnosis is suspected based on the symptoms, and may be verified by testing the vaginal discharge and finding a higher than normal vaginal pH, and large numbers of bacteria. [6] BV is often confused with a vaginal yeast infection or infection with Trichomonas. [7] Usually treatment is with an antibiotic, such as clindamycin or metronidazole.
