Trypanosoma burresoni n. sp. was present in 62% of 284 American eels (
Anguilla rostrata) collected in 1987-1989 from the Saint Lawrence Rive
r and Lake Ontario. This is a slender, monomorphic trypanosome with an
ovate, anteriorly located nucleus and a round, subterminal kinetoplas
t. The undulating membrane is well developed, and the free flagellum i
s less than half body length. Experimental infections of T. burresoni
were produced in the crop but not the proboscis sheath of the laborato
ry-reared leeches Hemiclepsis marginata and Desserobdella phalera. Try
panosomes that developed in D. phalera were not infective to eels. In
culture, a dose-dependant inhibition of multiplication was observed by
adding NaCl to the medium. Cultures that contained metatrypanosomes w
ere not infective to eels.
