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 …
Parasitism Of Hylodes Phyllodes (Anura: Cycloramphidae) By Hannemania Sp. (Acari: Trombiculidae) In An Area Of Atlantic Forest, Ilha Grande, Southeastern Brazil, F. H. Hatano, Donald Gettinger, M. Van Sluys, C. F. D. Rocha
Parasitism Of Hylodes Phyllodes (Anura: Cycloramphidae) By Hannemania Sp. (Acari: Trombiculidae) In An Area Of Atlantic Forest, Ilha Grande, Southeastern Brazil, F. H. Hatano, Donald Gettinger, M. Van Sluys, C. F. D. Rocha
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
We studied some parameters of the parasitism by the mite Hannemania sp. on the endemic frog Hylodes phyllodes in the Atlantic Forest of Ilha Grande (Rio de Janeiro State, Brazil). Prevalence, mean abundance, mean intensity and total intensity of infestation, body regions infected, and host sexual differences in parasitism rate of the larvae of Hannemania sp. on individuals of H. phyllodes were assessed. Prevalence was 86.5 % (N = 37; total of 1,745 larvae of Hannemania sp) for male hosts and 91.7 % (N =12; total of 330 larvae) for female hosts, with no significant difference between the sexes. Overall …
