What is Trichomoniasis caused by?

Trichomoniasis is caused by a single-celled protozoan known as Trichomonas vaginalis. This organism is a type of flagellated protozoan that thrives in the human urogenital tract. Understanding that Trichomonas vaginalis is a protozoan is essential in recognizing the distinct biological nature of the pathogen, which differs significantly from bacteria, fungi, and viruses in terms of structure, reproduction, and treatment options. For example, while bacterial infections are generally treated with antibiotics, protozoan infections may require specific antiparasitic medications. This highlights the importance of accurately identifying the causative agent for effective treatment and management of the infection.
