Summary: The blood of wild rodents captured alive in the field station of Casa Grande, municipality of Salesópolís, State of São Paulo was examined for hemoparasites. Trypanosomas of the subgenus Herpetosoma were discovered in the blood of 4 specimens of Proechimsis iherinçi, The parasites showed an average size of 21.7 J.Lm and an average nuclear index equivalent to 1.9. Attempts to cultivate the trypanosomas in NNN, Lit and Ducrey media failed. However, when Ducrey medium was added 2% of blood of Proechim.us 'iheringi there was abundant growth of mastigotes. Inoculation of Mus mUBculus, Akodon sp., Oryzomys sp. and Cricetus auratus were negative; however, inoculation of laboratory-born and reared Proechimys iheringi was successful and there was circulation of the parasite in the blood.It is suggested that the parasites isolated belong to a new species considering the behavior and specificity of the subgenus Herpetosoma to vertebrate hosts and the characteristics of the ísolates.

Esses flagelados mostraram tamanho médio de 21,7 p,m e índice nuclear médio equivalente a 1,9. As tentativas de cultivo deste protozoário em meios de NNN, LIT e Ducrey, resultaram negativas; todavia, quando se semeou o tripanossomídeo em meio de Ducrey, modificado pela adição de 2% de sangue de Proechimys iheringi, obteve-se intensa proliferação de formas epimastigotas. As inoculações experimentais em Mus musculus, Akodon sp., Oryzomys sp. e Cricetus auratus resultaram negativas; entretanto, quando se procedeu à inoculação em Proechimue iheringi, nascido em laboratório, a inoculação resultou positiva com parasitemia patente. Todas as tentativas de infectar triatomíneos mostraram-se negativas. Considerando aspectos relativos ao problema da especificidade do subgênero Herpetosoma em relação ao hospedeiro vertebrado e os valores biométricos encontrados nos exemplares examinados, admite-se que estes flagelados pertençam à espécie ainda não descrita.Instituto Adolfo Lutz1984-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://periodicos.saude.sp.gov.br/RIAL/article/view/3682610.53393/rial.1984.v.44.36826Instituto Adolfo Lutz Journal - RIAL; Vol. 44 No. 1 (1984); 47-53Revista del Instituto Adolfo Lutz - RIAL; Vol. 44 Núm. 1 (1984); 47-53Revista do Instituto Adolfo Lutz; v. 44 n. 1 (1984); 47-531983-38140073-9855reponame:Revista do Instituto Adolfo Lutz (Online)instname:Instituto Adolfo Lutzinstacron:IALporhttps://periodicos.saude.sp.gov.br/RIAL/article/view/36826/35042Copyright (c) 1984 José Eduardo Tolezano, Pedro Paulo Chieffi, Rosa Maria Donini Souza Dias, Elizabeth Visone Nunes, Osvaldo Martinez D'Andrade, Luís Eloy Pereira, Domingas Maria Aparecida Grispino Vieira Torres, Norival Lupettiinfo:eu-repo/semantics/openAccessTolezano, José EduardoChieffi, Pedro PauloDias, Rosa Maria Donini SouzaNunes, Elizabeth VisoneD'Andrade, Osvaldo MartinezPereira, Luís EloyTorres, Domingas Maria Aparecida Grispino VieiraLupetti, Norival2025-03-13T14:47:55Zoai:ojs.periodicos.saude.sp.gov.br:article/36826Revistahttps://periodicos.saude.sp.gov.br/RIAL/indexPUBhttps://periodicos.saude.sp.gov.br/RIAL/oairial@saude.sp.gov.brhttps://doi.org/10.53393/rial1983-38140073-9855opendoar:2025-03-13T14:47:55Revista do Instituto Adolfo Lutz (Online) - Instituto Adolfo Lutzfalse
