Coccídios de diferentes espécies de passeriformes do Sudeste brasileiro: taxonomia e ecologia

Abstract

The families of the order Passeriformes can be parasitized by several coccidian species, mainly of the genera Isospora Schneider, 1881 and Eimeria Schneider, 1875. In this context, the current work aimed to identify, characterize and quantify species of coccidian parasites of the families Thamnophilidae, Tyrannidae, Conopophagidae and Icteridae in Itatiaia National Park (PNI) mainly. Nineteen expeditions were carried out at the PNI, and three other expeditions were carried out in two different locations: Cacaria and Barra Mansa. Birds were captured with mist nets. From all 204 bird specimens were captured: 100 taminophilidae, 89 tyrannids, 7 conopophagids and 8 icterids, after processing the samples, observed to be coccidians of the genera Isospora or Eimeria from four families addressed in this study. Thus, the current work presents a review of the scientific literature on the themes of ecology and taxonomy of coccidia of Thamnophilidae, Tyrannidae, Conopophagidae and Icteridae, and, as a result, five scientific articles in chronological order describing a new host Cacicus haemorrhous (Linnaeus, 1766) and locality (PNI) for Isospora bellicosa Upton, Stamper and Whitaker, 1995, and a new species Isospora guaxi Silva & Berto, 2017 parasitizing C. haemorrhous in the family Icteridae; a new species Isospora lopesi Silva-Carvalho & Berto, 2018, from Platyrinchus mystaceus Vieillot, 1818 at PNI in the Tyrannidae family; a new host Pyriglena leucoptera (Vieillot, 1818) and locality (PNI) for Isospora sagittulae McQuistion and Capparella, 1992 in the Thamnophilidae family; a new species Isospora borbai Silva-Carvalho et Berto, 2019 parasitizing two distinct hosts, Conopophaga melanops (Vieillot, 1818), and Conopophaga lineata (Wied, 1831) in the Conopophagidae family; and finally a new host Dysithamnus mentalis (Temminck, 1823) for Isospora parnaitatiaiensis Silva, Rodrigues, Lopes, Berto, Luz, Ferreira, Lopes, 2015 in the Thamnophilidae family in PNI.
