n. sp. and coinfection in (Aves: Cariamiformes): first mitochondrial genome analysis and morphological description of a leucocytozoid in Brazil.

The distribution of avian haemosporidians of the genus in the Neotropics remains poorly understood. Recent studies confirmed their presence in the region using molecular techniques alone, but evidence for gametocytes and data on putative competent hosts for are still lacking outside highland areas. We combined morphological and molecular data to characterize a new species infecting a non-migratory red-legged seriema (), the first report of a competent host for in Brazil.

Fatal toxoplasmosis in a vinaceous Amazon parrot (Amazona vinacea).

Toxoplasmosis was diagnosed in a vinaceous Amazon parrot based on histopathology and immunohistochemistry. The bird was prostrate on the bottom of the cage and died. Necropsy revealed edema and congestion of the lungs, cloudy air sacs, and mild hepatomegaly.

Fatal coccidiosis by Isospora icterus (Upton & Whitaker, 2000) in captive Campo Troupial (Icterus jamacaii) in Brazil.

An outbreak of coccidiosis by Isospora icterus (I. icterus, Upton & Whitaker, 2000) in captive Campo Troupial (Icterus jamacaii) (Gmelin, 1788) at the Wild Animals Triage Center (IBAMA, Belo Horizonte, Brazil) is described. Clinical history and the necropsy findings documented diarrhea with diffuse necrotic enteritis.
