New observations from the intestinal fauna of Kerodon rupestris (Wied, 1820) (Rodentia, Cavidae), Brazil: a checklist spanning 30,000 years of parasitism

Abstract This checklist of parasites of Kerodon rupestris, an endemic rodent from the Brazilian semiarid region, revealed records of 25 enteroparasite taxa comprising Cestoda (Anoplocephalidae), Trematoda, Acanthocephala and Nematoda (Ancylostomidae, Ascarididae, Heterakidae, Oxyuridae, Pharyngodonidae, Trichuridae, Capillariidae, Trichostrongylidae, and Strongyloididae), and two taxa of coccidian. Paleoparasitological and parasitological studies published until 2019 were assessed in the present study and locality information, site of infection, sample dating, and host data were summarized from each reference. Analyses of recent feces and coprolites revealed the highest species richness in the Piauí State. The chronological data corroborated that Trichuris spp. and oxyurids are part of the parasitic fauna of K. rupestris. This represents the first checklist of intestinal parasites from K. rupestris.
