Trichomoniasis -------------- One of the most commonly recognized parasites of snakes is another protozoan, Trichomonas. This organism is often noted in the stools of snakes when routine direct examinations are undertaken. Infection with Trichomonas may result from ingestion of mice and rats, both of which often harbor the parasite without showing signs of illness. Infected snakes may exhibit no signs or those associated with gastrointestinal disease (inappetence, vomiting, diarrhea). Some infected snakes may also have bacterial disease at the same time. Some experts remain unconvinced that this parasite, by itself, can produce disease in snakes because infected snakes are often suffering from amebiasis at the same time. The most prudent course of action is to treat all snakes harboring the parasite. Fortunately, the treatment for trichomoniasis is usually effective in eliminating the organism that causes amebiasis. A veterinarian should be consulted regarding diagnosis and treatment of this parasitic disease.
