Abstract
Isospora vanriperorum from the green-winged saltator (Saltator similis) is described in Southeastern Brazil. Oocysts are spherical to subspherical, 19.4-26 by 18.3-26μm (23.1 by 22.4μm), shape index 1.04 with a single layered wall, fine, smooth and yellowish. Micropyle and residuum are absents, but one elliptical polar granule is present. Sporocysts are ovoid, 14.5-20.2 by 8.1-12.5μm (16.3 by 10.8μm), shape index 1.53 with prominent Stieda body, barely discernible substieda body and residuum centered and granulated.
Highlights
The green-winged saltator Saltator similis Lafresnaye and D’Orbigny, 1837 is a native bird of South America
The aim of this paper is to report and describe the sporulated oocysts of I. vanriperorum from the green-winged saltator, S. similis from Southeastern Brazil
They were placed into plastic vials containing potassium dichromate solution (K2Cr2O7) at 2.5% 1:6 v/v and transported to the Laboratório de Coccídios e Coccidioses at Projeto Sanidade Animal (Embrapa/UFRRJ), Departamento de Parasitologia Animal, Instituto de Veterinária da Universidade Federal Rural do Rio de Janeiro
Summary
The green-winged saltator Saltator similis Lafresnaye and D’Orbigny, 1837 is a native bird of South America. This species has a large range, with an estimated global extent of occurrence of 3,100,000 km. Coccidiosis associated with genus Isospora in birds of the Emberizidae family, buntings and sparrows, was reported since Labeé (1896), where Isospora oocysts were described how the yellowhammer, Emberiza citrinella (DUSZYNSKI; COUCH, 2004). Isospora vanriperorum was primarily described in northern cardinal, Cardinalis cardinalis, in Hawaii by Levine et al (1980). The aim of this paper is to report and describe the sporulated oocysts of I. vanriperorum from the green-winged saltator, S. similis from Southeastern Brazil
