| Abstract in Portuguese | Os autores apresentam uma revisão da hemogregarina parasita de rãs do gênero Leptodactylus. A posisção sistemática sob o ponto de vista genérico fica definida com os estudos do ciclo no vetor Haementeria lutzi, publicados em nota preliminar por um dos autores (Pessoa 24) quando utilizou rãs L. petadactylus em trabalho experimental. Este trabalho experimental continua sendo desenvolvido no Laboratório de Protozoologia do Instituto Oswaldo Cruz, utilizando a rã L. ocellatus e as sanguessugas Haementeria vizuttoi e Haementeria gracilis. Algumas técnicas citoquímicas foram empregadas para melhor caracterização dos esquizontes e das granulações do citoplasma das formas sanguíneas. | pt_BR |

| Abstract | The main object of the present paper is to furnish a brief account to the knowledgement of Protozoa parasitic in common Brazilian frog of the genus Leptodactylus for general students in Zoology and for investigators that use this frog as a laboratory animal. Hepatozoon leptodactyli (Haemogregarina leptodactyli) was found in two species of frogs - Leptodactylus ocellatus and L. pentadactylus - in which develop schizogony whereas sporogony occurs in the leech Haementeria lutzi as was obtainded in experimental conditions. Intracellular forms have been found in peripheral circulation, chiefly in erythrocytes, but we have found them in leukocytes too. Tissue stages were found in frog, liver, lungs, spleen, gut, brain and heart. The occurence of hemogregarine in the Central Nervous System was recorded by Costa & al,(13) and Ball (2). Some cytochemical methods were employed in attempt to differentiate gametocytes from trophozoites in the peripheral blood and to characterize the cystic membrane as well. The speorogonic cycle was developed in only one specie of leech. A brief description of the parasite is given. | pt_BR |
