Development of Hepatozoon caimani (Carini, 1909) Pessôa, De Biasi & De Souza, 1...

The sporogony of Hepatozoon caimani has been studied, by light microscopy, in the mosquito Culex fatigans fed on specimens of the caiman Caiman c. crocodilus showing gametocytes in their peripheral blood. Sporonts iniciate development in the space between the epithelium of the insect gut and the elastic membrane covering the haemocoele surface of the stomach. Sporulating oocysts are clustered on the gut, still ...

Eimeria peltocephali n. sp., (Apicomplexa:Eimeriidae) from the Freshwater Turtl...

The oocyst is described of Eimeria peltocephali n.sp. from faeces of the freshwater turtle Peltocephalus dumerilianus from Barcelos, State of Amazonas, Brazil. Sporulation is exogenous and fully developed oocysts are elongate, ellipsoidal or cylindrical, frequently curved to a banana-shape, 54.4 ×19.1 (37.5 - 68.7 × 18.7-20.0 μm), shape-index 2.8 (1.8 -3.9). The oocyst wall is a single thin, colourless layer ab...

Characterization of Endotrypanum Parasites Using Specific Monoclonal Antibodies

A large number of Endotrypanum stocks (representing an heterogeneous population of strains) have been screened against a panel of monoclonal antibodies (MAbs) derived for selected species of Endotrypanum or Leishmania, to see whether this approach could be used to group/differentiate further among these parasites. Using different immunological assay systems, MAbs considered specific for the genus Endotrypanum (...

Como parte do programa do laboratorio de Parasitología do INPA, na procura dos vetores e reservatórios da Leishmaniose, foi realizado durante o periodo de 1978 até 1981, um levantamento da fauna flebotomínica, em oito localidades da Rodovia BR-319 (Manaus-Humaita). Capturamos 57 espécies44 do gênero Lutzomyiae 13 de Psychodopygus. Os métodos de coleta usados foramcapturas nos troncos das árvores, isca humana e ...

On Eimerla bragancaensis n. sp. (apicomplexa: Eimeriidae) and tissue-cysts of a...

A description is given of the mature oocysts and endogenous stages of Eimeria bragancaensis n. sp., from the small intestine of the bat Peropteryx macrotis from north Brazil. Oocysts are spherical to subspherical, 15.9 × 14.6 pm (range 14-17 × 14-17.7). The wall is of two layers: an outer, thicker one which is of a brownish-yellow colour and striated (pitted), and an inner one which is thin and colourless. The ...

Trypanosomes of the subgenus Megatrypanum from armadillos (Xenarthra:Dasypodidae).

A new species of trypanosome, Trypanosoma (Megatrypanum) peba, is described from the peripheral blood of the armadillo Euphractus sexcinctus setosus from Bahia State, Brazil. Ten out of 29 specimens of the armadillo Dasypus novemcinctus from Pará State were found to have trypanosomes, including epimastigote forms, in impression smears of subcutaneous lymph nodes. The trypanosomes from D. novemcinctus are illust...

Species diversity and flagellate infections in the sand fly fauna near Porto Gr...

Forty-six species of Lutzomyia and one species of Brumptomyia were identified among 20,008 sand flies collected in central Amapá. L. squamiventris maripaensis, L. infraspinosa, L. umbratilis and L. ubiquitalis accounted for 66% of the specimens caught in light traps, and L. umbratilis was the commonest of the 16 species found on tree bases. Seven species of Lutzomyia including L. umbratilis were collected in a ...
