Trichominosis is a rare parasitic infection caused by the protozoan parasite Trichomonas vaginalis, primarily affecting the urogenital tract. It is commonly associated with trichomoniasis, which is a sexually transmitted infection (STI) characterized by symptoms such as itching, discharge, and discomfort. Diagnosis is typically made through microscopic examination or laboratory tests, and treatment usually involves antibiotics, such as metronidazole. While it predominantly affects women, men can also be carriers and transmit the infection.
