Theileria Electrophori N.Sp., A Parasite Of The Electric Eel Electrophorus Electricus (Osteichthyes: Cypriniformes: Gymnotidae) From Amazonian Brazil, Ralph Lainson

Harold W. Manter Laboratory: Library Materials

The name Theileria electrophori n. sp. is proposed for a small parasite described in the erythrocytes of the electric eel, Electrophorus electricus, from Amazonian Brazil. Division of the organism in the erythrocyte produces only four bacilliform daughter cells which become scattered in the host cell, without a cruciform or rosette-shaped disposition. Exoerythrocytic meronts producing a large number of merozoites were encountered in Giemsa-stained impression smears of the internal organs, principally in the liver, and are presumably the source of the intraerythrocytic forms of the parasite. This developmental pattern is characteristic of piroplasms within the family Theileriidae, where the author …
