Morphological, ultrastructural, and molecular characterization of intestinal tetratrichomonads isolated from non-human primates in southeastern Brazil.

Non-human primates are our closest relatives and represent an interesting model for comparative parasitological studies. However, research on this topic particularly in relation to intestinal parasites has been fragmentary and limited mainly to animals held in captivity. Thus, our knowledge of host-parasite relationships in this species-rich group of mammals could be considered rudimentary.

The ruby-crowned tanager Tachyphonus coronatus Vieillot, 1822 (Passeriformes: Thraupidae) as a new host for Isospora ramphoceli Berto, Flausino, Luz, Ferreira, Lopes, 2010 in Brazil.

Despite 12 coccidian species had been recorded from passerines of the Thraupidae family, none of them has been reported in the Parque Nacional do Itatiaia, in Southeastern Brazil. This locality is a protected area with a high degree of vulnerability, and is considered a "conservation island" of biodiversity. The aim of the current work was describe Isospora ramphoceli Berto, Flausino, Luz, Ferreira, Lopes, 2010 from ruby-crowned tanagers Tachyphonus coronatus Vieillot, 1822 in the Parque Nacional do Itatiaia.

Isospora albicollis (Apicomplexa: Eimeriidae) in thrushes Turdus spp. (Passeriformes: Turdidae), in southeastern Brazil.

The aim of the present study was to report and describe Isospora albicollis Lainson and Shaw, 1989 parasitizing a white-necked thrush Turdus albicollis Vieillot, 1818 and a pale-breasted thrush Turdus leucomelas Vieillot, 1818 in two different localities: the Itatiaia National Park and Cacaria, in southeastern Brazil. The oocysts identified were ovoidal, 24.4 × 19.

Some remarks on the distribution and dispersion of Coccidia from icterid birds in South America: Isospora guaxi n. sp. and Isospora bellicosa Upton, Stamper & Whitaker, 1995 (Apicomplexa: Eimeriidae) from the red-rumped cacique Cacicus haemorrhous (L.) (Passeriformes: Icteridae) in southeastern Brazil.

A new species of coccidian, Isospora guaxi n. sp., and Isospora bellicosa Upton, Stamper & Whitaker, 1995 (Protozoa: Apicomplexa: Eimeriidae) are recorded from red-rumped caciques Cacicus haemorrhous (L.

A new isosporoid coccidia (Apicomplexa: Eimeriidae)from the southern house wren Troglodytes musculus Naumann, 1823 (Passeriformes: Troglodytidae) from Brazil.

A new isosporoid coccidian species (Protozoa: Apicomplexa: Eimeriidae) is reported from the southern house wren Troglodytes musculus, a very well distributed species in South and Central America. Isospora corruirae sp. nov.

New approaches for morphological diagnosis of bovine Eimeria species: a study on a subtropical organic dairy farm in Brazil.

Bovine eimeriosis or coccidiosis is an intestinal disease caused by Eimeria spp. which is related to gastrointestinal disorders and, in some cases, death. The current work aimed to identify and provide detailed morphological characteristic features of the different Eimeria spp.

A new species of Isospora Schneider, 1881 (Apicomplexa: Eimeiriidae) from the grey-hooded attila Attila rufus Vieillot, 1819 (Passeriformes: Tyrannidae) on the Marambaia island, Brazil.

The New World tyrant-flycatcher (Tyrannidae) Attila rufus (Vieillot, 1819) is commonly known as grey-hooded attila or 'capitão-de-saíra' in Brazil (Sick 1997; CBRO 2014). This species has a wide distribution and their population trends appear to be stable; therefore, it is least concern according to IUCN (2015) criteria.

A new coccidian, Isospora parnaitatiaiensis n. sp. (Apicomplexa, Eimeriidae), from the white-shouldered fire-eye Pyriglena leucoptera (Passeriformes, Thamnophilidae) from South America.

A new coccidian species (Protozoa: Apicomplexa: Isospora) parasitizing the white-shouldered fire-eye Pyriglena leucoptera (Vieillot, 1818) is described in the Parque Nacional do Itatiaia. This park is a protected area in southeastern Brazil with a high degree of vulnerability, representing a "conservation island" of biodiversity. Isospora parnaitatiaiensis n.

Coccidial dispersion across New World marsupials: Klossiella tejerai Scorza, Torrealba & Dagert, 1957 (Apicomplexa: Adeleorina) from the Brazilian common opossum Didelphis aurita (Wied-Neuwied) (Mammalia: Didelphimorphia).

Klossiella tejerai Scorza, Torrealba & Dagert, 1957 is a primitive coccidian parasite reported from the New World marsupials Didelphis marsupialis (Linnaeus) and Marmosa demerarae (Thomas). The current work describes K. tejerai from the Brazilian common opossum Didelphis aurita (Wied-Neuwied) in Southeastern Brazil, evidencing the coccidial dispersion across opossums of the same family.

Isospora pitiguari n. sp. (Apicomplexa: Eimeriidae) from the rufous-browed peppershrike (Aves: Passeriformes: Vireonidae) Cyclarhis gujanensis Gmelin, 1789.

In the current study, a new coccidian species (Protozoa: Apicomplexa: Eimeriidae), collected from the rufous-browed peppershrike Cyclarhis gujanensis Gmelin, 1789, is reported from Brazil. Isospora pitiguari n. sp.

Coccidia of New World psittaciform birds (Aves: Psittaciformes): Eimeria ararae n. sp. (Apicomplexa: Eimeriidae) from the blue-and-yellow macaw Ara ararauna (Linnaeus).

In the New World, the avian order Psittaciformes comprises 142 species, yet to date only 3 (2%) of the species have been examined for coccidia, and from these only four species of Eimeria Schneider, 1875 have been described. In this study, a new coccidian species (Protozoa: Apicomplexa: Eimeriidae) obtained from the blue-and-yellow macaw Ara ararauna (Linnaeus) is reported from Brazil. Oöcysts of Eimeria ararae n.
