Final answer:
Trichomoniasis is an STI caused by the protozoan Trichomonas vaginalis and is contracted primarily through sexual contact. Symptoms vary and are more likely in women, including vaginal discharge, itching, and irritation. It can be diagnosed with a vaginal smear and is treatable with specific medication.
Step-by-step explanation:
What is Trichomoniasis?
Trichomoniasis is a common sexually transmitted infection (STI) caused by the protozoan parasite Trichomonas vaginalis. The primary mode of contraction of trichomoniasis is through sexual contact with an infected person. This disease can affect both men and women, but symptoms are more common in women.
Causative Organism
The causative organism of trichomoniasis is Trichomonas vaginalis, a flagellated protozoan that has an amoeboid shape when attached to cells in the birth canal and an oval shape in culture. It is the most common nonviral STI.
Mode of Contraction
The mode of contraction for trichomoniasis is primarily through sexual intercourse, as the parasite is transmitted from one person to another.
Basic Symptoms
The basic symptoms of trichomoniasis can vary. Many people are asymptomatic, but when symptoms do occur, they may include urinary discomfort, genital irritation, itching, and discharge. Women may experience vaginal discharge, itching, burning, redness, and soreness of the genitalia, while men may have discharge from the phallus and burning after urination or ejaculation.
Diagnosis of trichomoniasis involves tests such as a vaginal smear. Treatment typically includes antiflagellate drugs like tinidazole and metronidazole.
