摘要

Human-modified landscapes increasingly bring wildlife, domestic animals, and humans into spatial overlap, with important consequences for the composition and distribution of parasite communities. We characterize the gastrointestinal parasite communities in free-ranging black-horned capuchins [hereafter capuchin monkey(s); Sapajus nigritus cucullatus], domestic dogs (Canis lupus familiaris), and cattle (Bos taurus) living in a human-wildlife interface in the Atlantic Forest of Misiones, Argentina. We analyzed 197 fecal samples from capuchin monkeys, 71 from domestic dogs, and 29 from cattle collected across six study sites and conducted 50 semi-structured interviews with residents to characterize domestic animal management practices. We recorded 15 parasite taxa in capuchin monkeys, including protozoans, nematodes, acanthocephala, and cestodes, several of which had not been previously reported for this species. Interviews revealed limited implementation of preventive veterinary care, widespread free-ranging domestic dogs, and frequent spatial overlap between domestic animals and capuchin monkeys. Our results underscore the value of descriptive parasitological surveys for identifying parasite groups at interface contexts that warrant further investigation using molecular approaches, as well as informing surveillance and management priorities within a One Health framework.
