Abstract

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.

巴西南马托格罗索州巨食蚁兽中刚地弓形虫血清流行病学研究。

监测是“同一个健康”的重要组成部分；然而，从自由放养的动物身上获取和保存足够的生物样本的挑战阻碍了对野生动物的疾病监测。弓形虫是引起弓形虫病的病原体，弓形虫病是一种世界性的人畜共患病，在巴西流行率很高。关于巨食蚁兽（Myrmecophaga tridactyla）弓形虫病的文献有限；因此，本研究旨在评估巴西中西部三叉虫中弓形虫的血清阳性率。2016年至2021年，作为野生动物保护研究所（ICAS）研究的一部分，从南马托格罗索州塞拉多（Cerrado）（n=65）和潘塔纳尔（n=6）生物群落中收集了71只自由放养动物的血液样本。采用改良的凝集试验检测抗t。刚抗体。总体而言，62%（44/71）的自由放养食蚁兽检测呈阳性，滴度从16到4096不等，证实巴西该地区的巨型食蚁兽暴露于弓形虫。Anti-T。在潘塔纳尔湿地和塞拉多热带稀树草原生物群落的食蚁兽中均检测到弓形虫抗体，表明两者均存在弓形虫。

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.
