Seroprevalence of Toxoplasma gondii in Giant Anteaters (Myrmecophaga tridactyla) in Mato Grosso Do Sul, Brazil.
Surveillance is an important component of One Health; however, disease surveillance in wild animals is hindered by challenges in obtaining and preserving adequate biological samples from free-ranging animals. The protozoan Toxoplasma gondii is the etiologic agent causing toxoplasmosis, a worldwide zoonosis with a high prevalence in Brazil. There is limited literature on toxoplasmosis in giant anteaters (Myrmecophaga tridactyla); therefore, this study aimed to evaluate the seroprevalence of T. gondii in M. tridactyla from midwest Brazil. Blood samples from 71 free-ranging animals from the Cerrado (n=65) and Pantanal (n=6) biomes in Mato Grosso do Sul state, were collected from 2016 to 2021, as part of Wild Animals Conservation Institute (ICAS) studies. A modified agglutination test was used to detect anti-T. gondii antibodies. Overall, 62% (44/71) of free-ranging anteaters tested positive, with titers ranging from 16 to 4,096, confirming exposure of giant anteaters in this area of Brazil to T. gondii. Anti-T. gondii antibodies were detected in anteaters from both the Pantanal wetland and Cerrado savanna biomes, indicating the presence of T. gondii in both.
期刊介绍：
The JWD publishes reports of wildlife disease investigations, research papers, brief research notes, case and epizootic reports, review articles, and book reviews. The JWD publishes the results of original research and observations dealing with all aspects of infectious, parasitic, toxic, nutritional, physiologic, developmental and neoplastic diseases, environmental contamination, and other factors impinging on the health and survival of free-living or occasionally captive populations of wild animals, including fish, amphibians, reptiles, birds, and mammals. Papers on zoonoses involving wildlife and on chemical immobilization of wild animals are also published. Manuscripts dealing with surveys and case reports may be published in the Journal provided that they contain significant new information or have significance for better understanding health and disease in wild populations. Authors are encouraged to address the wildlife management implications of their studies, where appropriate.
