Trichomonas

Trichomonas (commonly known as ‘trike') is a sexually transmitted infection (STI) caused by a parasite. It can cause infection of the vagina or cervix (neck of the womb) in women and the urethra (urine passage) in both women and men. Trichomonas is one of the most common STIs in some parts of the world but it is not as common in Australia.
