Cerdocyon thous presents a wide geographic distribution in Brazil and its role as a possible Leishmania infantum reservoir in a visceral leishmaniasis (VL) transmission cycle regardless of dogs (Canis familiaris) has been discussed. From this perspective, this work describes the occurrence and use of the habitat by Cerdocyon thous in a Lutzomyia longipalpis occurrence area Teresina (Piaui - Brazil), VL endemic region. Three specimens of C. thous were monitored with the use of radio telemetry and trails and footprints, seeking to find possible natural dens in order to collect the sanflies from the site. Luminous CDC and Damasceno traps were simultaneously installed at the visited sites, where two specimens of L. longipalpis and one L. termitophila were captured. The identification of the dens and trails, allows us to infer that the dens are not used only by the C. thous. Finding the VL vector in natural C. thous natural dens, reinforces the hypothesis of transmission of Le. infantum in the outskirts of the large urban centers, in a cycle that independs from dogs.
食蟹狐在巴西有着广泛的地理分布，其作为内脏利什曼病（VL）传播周期中可能的婴儿利什曼原虫宿主的作用，且不依赖于犬类（家犬），这一点已被讨论。从这个角度来看，这项工作描述了食蟹狐在长须罗蛉出现地区特雷西纳（巴西皮奥伊州）——VL流行地区的栖息地出现情况及利用情况。使用无线电遥测以及踪迹和脚印对三只食蟹狐标本进行了监测，试图找到可能的天然巢穴，以便从该地点收集白蛉。在访问的地点同时安装了发光的疾控中心诱捕器和达马西诺诱捕器，捕获了两只长须罗蛉标本和一只嗜白蚁罗蛉标本。巢穴和踪迹的确定使我们能够推断，这些巢穴并非仅被食蟹狐使用。在食蟹狐的天然巢穴中发现VL传播媒介，强化了婴儿利什曼原虫在大型城市中心郊区以不依赖犬类的周期进行传播的假说。
