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.

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.

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.

Article Synopsis
  • * All monkeys tested negative for Brucella spp. and Leptospira spp., while 75% of Alouatta caraya and 16.6% of Callithrix penicillata showed positive results for T. gondii.
  • * The study highlights important implications for the conservation and health management of these monkey populations.

Brazil is one of the regions with the highest prevalences of Toxoplasma gondii in humans and animals. Because free-range chickens become infected by feeding from ground contaminated with oocysts, the prevalence of T. gondii in this host has been widely used as an indicator of the strains prevalent in the environment.

Use of serological tests in the diagnosis of infectious diseases in wild animals has several limitations, primarily the difficulty of obtaining species-specific reagents. Wild canids, such as maned wolves (Chrysocyon brachyurus), are highly predisposed to infection by Toxoplasma gondii and, to a lesser extent, to Neospora caninum. The aim of the present study was to evaluate homologous, heterologous, and affinity conjugates in enzyme-linked immunosorbent assays (ELISAs) and indirect fluorescent antibody tests (IFATs) for detecting immunoglobulin (Ig) G antibodies against T.

The Frontal Assessment Battery (FAB) is a short neuropsychological tool aiming to assess executive functions at the bedside. Two-hundred and thirty-six normal controls were administered the FAB and three other tasks assessing attentional and executive functions. The FAB was also administered to 28 patients suffering from mild Alzheimer's disease (AD, n.

The main purpose of the present study was to investigate the occurrence of antibodies against T. gondii and N. caninum in captive maned wolves from Brazil, considering that little information is available at the literature about infections by these parasites in this wild animal.
