ABSTRACT A new coccidian species parasitizing white-necked thrushes Turdus albicollis Vieillot, 1818 is described from the Parque Nacional do Itatiaia, in Southeastern Brazil. Isospora machadoae sp. nov. has oocysts that are sub-spherical, 22.2 × 21.2 µm, with bilayered wall, ~1.3 μm thick. Outer layer is rough with micropyle and micropyle cap. Ooc...
Abstract The little owl Athene noctua (Scopoli, 1769) is a small raptor that is widely distributed from northern to southern Portugal and several other countries in Europe, Asia and North Africa, and which has been introduced into New Zealand. In the current study, 18 fecal samples were collected from little owls kept at the Lisbon Center for Wild ...

The felids are the only definitive hosts of Toxoplasma gondii, which could excrete oocysts into the environment and provide an infection source for toxoplasmosis in various warm-blooded animal species, particularly the captive felids that live close to human communities. The infection rate of the captive felids is a perfect standard in detecting th...
Abstract 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 identifie...

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...

During May and July 2016, 32 eastern small-footed myotis (Myotis leibii) were collected from five counties of northwestern Arkansas and their faeces examined for coccidian parasites. Four of 32 (13%) M. leibii harboured an eimerian that we describe here as new. Oocysts of Eimeria sassei sp. n. were ovoidal to ellipsoidal with a bi-layered wall and ...

The results of identification of Eimeria spp. oocysts based on fecal examination of cattle of the first year of life from 7 farms of Zhytomyr and Kyiv regions of Ukraine are presented in article. Nine species of Eimeria, namely, Eimeria zuernii (Rivolta, 1878) Martin, 1909; E. bovis (Zublin, 1908) Fiebiger, 1912; E. ellipsoidalis Becker and Frye, 1...

Histologic lesions incidental to the cause of death were observed in the adrenal glands of 17 subadult and adult leatherback sea turtles ( Dermochelys coriacea ) found dead or moribund on or near shore in North America. Round bodies, 250-300 μm in diameter composed of an outer capsule and large multinucleated cells surrounding a central mass of ace...

Coprological analysis of a sample from one free-living hedgehog was done with the use of a direct flotation method with additional incubation of fecal material. The study revealed three types of eggs and oocysts in the feces. The most commonly diagnosed were oocysts of Isospora rastegaievae (543/3g), while oocysts of Monocystis sp. (267/3g) and egg...

The aim of this study was to contribute to the better understanding of the relative epidemiological importance of different modes of infection with respect to horizontal transmission of Toxoplasma gondii in endemic settings. We investigated the prevalence of salivary IgA against a sporozoite-specific embryogenesis-related protein (TgERP) in a highl...
