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.

Highlights

Infections caused by parasites have an important role in conservation biology, for management decisions and issues related to the biology of the host population (Hudson, 2005; Thompson et al, 2010)
Nineteen records were found in the literature that reported on fecal parasites; 6 (31.6%) were paleoparasitological analyses and 13 (68.4%) used recent feces of K. rupestris
We observed a large number of intestinal taxa in K. rupestris

Summary

Introduction

Infections caused by parasites have an important role in conservation biology, for management decisions and issues related to the biology of the host population (Hudson, 2005; Thompson et al, 2010). For many vertebrate species there is a deficiency in the knowledge of their parasite fauna, important data area lacking concerning components of biodiversity (Poulin and Morand, 2004). Rodents account for approximately 44% of extant mammal species (see Wolf and Sherman, 2007), and serve as reservoirs for. There are few parasite inventories from wild rodents in Brazil, and the Brazilian Northeast is especially deficient for these studies
