Trypanosoma Species of Amphibians

Amphibians harbor a broad spectrum of species, the cell body of which appears striated when studied by light microscopy. The stages of the different species range from 54 to 78 μm in length, their anterior pole is pointed, and the flagellum surpasses the anterior end by one half or one third of the body length. For example, Trypanosoma diemyctyli of newt or eft. Vectors are leeches (e.g., Batrachobella picta). Other described species are T. ambystoma of the Pacific coast newt or T. granulosa, T. rotatorum, T. ranarum in frogs (e.g., Rana pipiens).
