Animal trypanosomiasis, also known as nagana and nagana pest, or sleeping sickness, is a disease of vertebrates. The disease is caused by trypanosomes of several species in the genus Trypanosoma such as Trypanosoma brucei. Trypanosoma vivax causes nagana mainly in West Africa, although it has spread to South America.
How do you treat patients who have trypanosomiasis?
The acute phase of trypanosomiasis (Chagas disease) is treated with nifurtimox or benznidazole. Cases of congenital Chagas disease have been successfully treated with either drug. A single case of successful treatment of an adult with posaconazole (after failure of therapy with benznidazole) has been reported.
What is trypanosomiasis disease in animals?
Trypanosomiasis is a parasitic disease caused by species of flagellate protozoa belonging to the genus Try-panosoma which inhabit the blood plasma and various body tissues and fluids. These parasites are found in many animals but seem to be pathogenic only for mammals, including man.
How does trypanosomiasis affect animals?
The trypanosomes infect the blood of the vertebrate host, causing fever, weakness, and lethargy, which lead to weight loss and anemia; in some animals the disease is fatal unless treated. The trypanosomes are transmitted by tsetse flies.
What is canine trypanosomiasis?
Trypanosomiasis (T.) This is a species of parasitic euglenoid protozoan. They typically bore into tissue in another organism and feed on the blood or lymph. They are associated with heart disease in canines as the parasites attacks the heart muscle causing major damage.

What does the name trypanosomiasis mean?
Trypanosomiasis or trypanosomosis is the name of several diseases in vertebrates caused by parasitic protozoan trypanosomes of the genus Trypanosoma. In humans this includes African trypanosomiasis and Chagas disease.
How does Trypanosoma infect the body?
Trypanosoma cruzi is a species of parasitic euglenoid trypanosomes. This species causes the trypanosomiasis diseases in humans and animals in America. Transmission occurs when the reduviid bug deposits feces on the skin surface and subsequently bites; the human host then scratches the bite area, which facilitates penetration of the infected feces.
What does Trypanosoma mean?
