Serological evidence of infection in (Spix, 1825) and (Linnaeus, 1758).

is a protozoan with worldwide prevalence, known to affect a large variety of warm-blooded hosts. However, its ability to induce long-lasting infections in cold-blooded animals remains unclear. The most likely source of infection is through consumption of meat containing tissue cysts or by ingestion of food or water contaminated with oocysts.

Prevalence of antibodies against Neospora spp. and Sarcocystis neurona in donkeys from northeastern Brazil.

Sarcocystis neurona and Neospora hughesi are coccidian protozoa that can cause neurological illness in horses in America. In this study we report seroprevalence of Neospora spp. andS.

Epidemiological aspects of Toxoplasma gondii infection in riverside communities in the Southern Brazilian Amazon.

Introduction: Toxoplasma gondii infection is widely prevalent in humans and other animals worldwide. Information on the prevalence of T. gondii infection is scarce in some regions of Brazil, including riverside communities along the Amazon River basin.

Occurrence of antibodies against Toxoplasma gondii and its isolation and genotyping in donkeys, mules, and horses in Brazil.

The occurrence of antibodies against Toxoplasma gondii was determined in donkeys, mules, and horses from different regions of Brazil. Serum samples from 304 donkeys (67.11%), 118 horses (26.

Serologic evidence of Toxoplasma gondii infection in wild birds and mammals from southeast Brazil.

In this study, serum samples of 53 wild animals from two different states from the southeast region of Brazil were analyzed for the presence of anti-Toxoplasma gondii antibodies by the modified agglutination test (MAT), with a cut-off of 1: 5 for birds and of 1: 25 for mammals. Out of the sampled animals, 27 were birds and 26 were mammals, and from this total, 83% (n = 44) were free-living animals. Antibodies were found in 13 mammals, from which 11 were free-living animals, and in five birds, all of which were free-living.
