Trypanosoma Gruby, 1843

The trypanosomes are parasites of all classes of vertebrates. Having been found initially in the blood of fish and frogs, trypanosomes have since been found in reptiles, birds, and mammals. Members of the genus Trypanosoma are typically transmitted between hosts by some type of invertebrate vector. One exception is Trypanosomaequiperdum which is transmitted between horses by during coitus. Trypanosomes are significant pathogens of man ansd animals throughout the tropics. There has, however, been little evidence that they are major pathogens of the domestic cat.
