Wild animals are hosts for many species of parasites which act as opportunistic or primary agents of disease. This study investigated the presence of endoparasites in the gastrointestinal tracts of wild animals from the State of Mato Grosso do Sul in the Cerrado, Atlantic Forest, and Pantanal biomes. From October 2022 to June 2024, fecal samples were collected from wild animals at two locations: Wildlife Rehabilitation Center (CRAS) in Campo Grande and the Paragem Municipal Natural Park (PNMP) in Dourados. A total of 109 fecal samples were collected: 96 from CRAS and 13 from PNMP and techniques of flotation and sedimentation were used. The prevalence of parasitism was 51.04% and 23.07% in the captive and free-living animals, respectively. The parasites found were nematodes (Strongyloidea, Ancylostomatidae, Ascaridida, Ascaropsinae, Toxocara spp., Capillarinae, Trichuris spp., Ascaris suum, Oxyurida, and nematode larvae), cestodes (Dipylidium spp. and Spirometra spp.), trematodes (Paragonimus spp.), and protozoa (Entamoeba spp., Eimeria spp., Cystoisospora spp., and Coccidia). The highest prevalence was observed for helminths of the Strongyloidea and Ancylostomatidae, followed by Coccidia and Entamoeba spp.. We highlight the importance of such studies to better understand the circulation of etiological agents that may pose a risk to animal and human health.
野生动物是许多寄生虫物种的宿主，这些寄生虫可作为机会性或原发性疾病病原体。本研究调查了来自南马托格罗索州塞拉多、大西洋森林和潘塔纳尔生物群落的野生动物胃肠道内寄生虫的存在情况。2022年10月至2024年6月，在两个地点采集了野生动物的粪便样本：大坎普的野生动物康复中心（CRAS）和多拉杜斯的帕拉任市立自然公园（PNMP）。共采集了109份粪便样本：96份来自CRAS，13份来自PNMP，并采用了浮选和沉淀技术。圈养动物和自由生活动物的寄生虫感染率分别为51.04%和23.07%。发现的寄生虫有线虫（圆线虫科、钩口科、蛔目、蛔亚科、弓首蛔虫属、毛细线虫科、鞭虫属、猪蛔虫、尖尾线虫目和线虫幼虫）、绦虫（复孔绦虫属和裂头绦虫属）、吸虫（并殖吸虫属）和原生动物（内阿米巴属、艾美耳球虫属、等孢球虫属和球虫）。圆线虫科和钩口科蠕虫的感染率最高，其次是球虫和内阿米巴属。我们强调此类研究对于更好地了解可能对动物和人类健康构成风险的病原体传播的重要性。
