The Caatinga is a Brazilian biome with limited studies on its wild mammal fauna, including the ectoparasitic relationships in these animals. This study aims to report the findings of fleas and ticks infesting wild animals rescued in the municipality of Mossoró, Rio Grande do Norte State (RN), Brazil, and treated at the Veterinary Hospital of the Universidade Federal Rural do Semi-Árido (HOVET-UFERSA). During the clinical assessments and physical examinations of the host animals (one male Cerdocyon thous L.; two females of Tamandua tetradactyla L.; one male Leopardus tigrinus Schreber; and one male Conepatus semistriatus Boddaert), fleas and ticks were collected. These ectoparasites were removed mechanically and sent to the Animal Parasitology Laboratory at UFERSA for identification. Identification was carried out based on morphology, with the aid of specific literature, stereomicroscopy, and light optical microscopy. From C. thous, two males of Amblyomma parvum Aragão and four female Pulex irritans (L.) fleas were recovered. From the adult female T. tetradactyla, one male of Rhipicephalus linnaei (Audouin), eight nymphs, and two males of Amblyomma auricularium (Conil) were collected. From the juvenile female T. tetradactyla, three nymphs of A. parvum and six female fleas of the species Tunga penetrans (L.) were recovered. From the male L. tigrinus, five females and one male flea of the species Ctenocephalides felis (Bouche) were collected. Finally, from the male C. semistriatus, two nymphs, 19 males, and six females of A. auricularium were recovered. This study contributes to expanding the knowledge of host-parasite relationships in free-living mammals in the Caatinga biome, in western Rio Grande do Norte.
卡廷加是巴西的一个生物群落，对其野生哺乳动物区系的研究有限，包括这些动物身上的体外寄生虫关系。本研究旨在报告在巴西北里奥格兰德州莫索罗市获救并在半干旱地区联邦农村大学兽医院（HOVET-UFERSA）接受治疗的野生动物身上发现的跳蚤和蜱虫。在对宿主动物（一只雄性食蟹狐Cerdocyon thous L.；两只雌性二趾食蚁兽Tamandua tetradactyla L.；一只雄性虎猫Leopardus tigrinus Schreber；以及一只雄性半带猪鼻臭鼬Conepatus semistriatus Boddaert）进行临床评估和体格检查时，收集了跳蚤和蜱虫。这些体外寄生虫通过机械方法去除，并送往UFERSA的动物寄生虫学实验室进行鉴定。鉴定基于形态学，借助特定文献、体视显微镜和光学显微镜进行。从食蟹狐身上，回收了两只微小扇头蜱Amblyomma parvum Aragão雄性和四只致痒蚤Pulex irritans (L.)雌性。从成年雌性二趾食蚁兽身上，收集到一只林氏硬蜱Rhipicephalus linnaei (Audouin)雄性以及八只若虫和两只耳状扇头蜱Amblyomma auricularium (Conil)雄性。从幼年雌性二趾食蚁兽身上，回收了三只微小扇头蜱若虫和六只穿皮潜蚤Tunga penetrans (L.)雌性。从雄性虎猫身上，收集到五只猫栉首蚤Ctenocephalides felis (Bouche)雌性和一只雄性。最后，从雄性半带猪鼻臭鼬身上，回收了两只耳状扇头蜱若虫、19只雄性和六只雌性。本研究有助于扩大对北里奥格兰德西部卡廷加生物群落中自由生活哺乳动物宿主-寄生虫关系的认识。
