In this context, this study aimed to identify, characterize and quantify coccidian species from Thamnophilidae in the Itatiaia National Park. Seven expeditions were performed at Itatiaia National Park, of which five were in conserved areas and two in areas around the park. A total of 184 species of birds were captured with mist nets, being 26 thaminophilid passerines. After fecal sampling and processing were observed coccidia of the genera Isospora and Eimeria. The species Isospora parnaitatiaiensis Silva, Rodrigues, Lopes, Berto, Luz, Ferreira, Lopes, 2015 was identified in two different hosts, Pyriglena leucoptera (Vieillot, 1818) and Dysithamnus mentalis (Temminck, 1823), and their oocysts were characterized as polymorphic, since the oocysts from P. leucoptera were more ellipsoidal and the oocysts from D. mentalis were more sub-spherical, which may be the result of speciation process/adaptation to these hosts. The intensities of infection in different hosts were relatively low, since that P. leucoptera and D. mentalis shed together an OoPD of 316 oocysts of I. parnaitatiaiensis, which can be explained by the conserved environment in the Itatiaia National Park and the insectivore feeding habit. Finally, the specificity occurred at the family level, because P. leucoptera and D. mentalis, both of Thamnophilidae family, have been reported as hosts of I. parnaitatiaiensis Os taminofil?deos, da mesma forma que outras fam?lias de Passeriformes, podem ser parasitados por diversas esp?cies de cocc?dios, principalmente dos g?neros Isospora Schneider, 1881 e Eimeria Schneider, 1875. Neste contexto, este trabalho teve por objetivo identificar, caracterizar e quantificar esp?cies de cocc?dios parasitos de Thamnophilidae do PNI. Foram realizadas sete expedi??es no Parque Nacional do Itatiaia, das quais cinco foram em ?reas mais preservadas e duas em ?reas no entorno do parque, as aves foram capturadas com o auxilio de redes de neblina, ao todos foram capturados 184 esp?cimes de aves sendo 26 taminofil?deos, ap?s o processamento das amostras observou ser cocc?dios do g?nero Isospora e Eimeria. A esp?cie Isospora parnaitatiaiensis Silva, Rodrigues, Lopes, Berto, Luz, Ferreira, Lopes, 2015 foi identificada em dois diferentes hospedeiros da fam?lia Thamnophilidae, Pyriglena leucoptera (Vieillot, 1818) e Dysithamnus mentalis (Temminck, 1823), sendo que seus oocistos foram caracterizados como polim?rficos, j? que os oocistos de P. leucoptera s?o mais elips?ides em rela??o aos oocistos de D. mentalis que tendem ao ser mais sub-esf?ricos, o que pode ser consequ?ncia do processo de especia??o/adapta??o ao hospedeiro. A intensidade de infec??o nos diferentes hospedeiros taminofil?deos positivos foram relativamente baixas, P. leucoptera e D. mentalis tiveram juntos um OoPD de 316 para os oocistos de I. parnaitatiaiensis, o que pode ser justificado pelo ambiente conservado do PNI e pelo h?bito alimentar inset?voro. Finalmente, a especificidade ocorreu em n?vel de fam?lia, pelo fato de P. leucoptera e D. mentalis, ambos da fam?lia Thamnophilidae, ter sido relatados como hospedeiros de I. parnaitatiaiensis

Coccidiosis as being limiting in nature, often asymptomatic, is observed in most of these cage birds, causing health problems and economic losses for both small and for large breeders.The principal objective of this research was to describe coccidiosis in cage birds located in the City of Teres?polis, from the mountainous region of the State of the Rio de Janeiro. The cage birds are kept as pets for their beauty as for their singing and mostly belong to the order Passeriformes In this study, oocysts recovered from feces of cage birds were species of the genus Isospora Schneider, 1881 identified by the phenotypic and morphometric characteristics. It could be observed that coccidiosis in cage birds in this study did not represent a limiting factor in this system of breeding in spite of the presence of coccidian oocysts in the feces of studied birds. A coccidiose por ser de car?ter limitante, muitas vezes assintom?tica, ? observada na maioria das aves de gaiola, causando problemas de sa?de e preju?zos econ?micos tanto para pequenos quanto para grandes criadores. Este trabalho teve como objetivo principal verificar a infec??o de cocc?dios em p?ssaros de gaiola do munic?pio de Teres?polis, localizado na Regi?o Serrana . As aves de gaiola s?o mantidas como mascotes tanto pela sua beleza como pelo seu canto, e em sua maioria pertencem ? ordem Passeriformes. Neste trabalho, os oocistos observados nas fezes desses p?ssaros de gaiola, foram identificados atrav?s das caracter?sticas fenot?picas e an?lise morfom?trica como esp?cies do g?nero Isospora Schneider, 1881. Observou-se que a coccidiose em p?ssaros de gaiola no presente estudo n?o foi fator limitante no sistema de cria??o, apesar da presen?a de oocistos de cocc?dios nas fezes das aves estudadas.
