A survey for helminth parasites in feral New World non‐human primate populations and its comparison with parasitological data from man in the region

Abstract:  A survey for helminth parasites in feral New World non‐human primates was conducted and compared with parasitological data from man in the region. A total of 835 fecal samples were collected from feral Aotus nancymae, A. vociferans, Saguinus labiatus, S. mystax, Saimiri boliviensis peruviensis, S. sciureus macrodon, Lagothrix lagotricha and Cacajao calvus rubicundus. In addition, adult parasites were collected from necropsies performed on monkeys that died during quarantine and in captivity. Helminth parasites shared by non‐human primates and man in Peru were Ancylostoma braziliensis and Ascaris lumbricoides, found in a captive L. lagotricha; Necator americanus, found in a captive C. calvus rubicundus; Hymenolepis diminuta, found in feral Aotus spp. and S. mystax; and a single Trichuris spp. specimen found in a feral S. sciureus macrodon.

Functional morphology of the tubular genital organs in the female owl monkey (Aotus spp.)

Studies on reproductive morphology are important to understand the reproductive cycle of non‐human primates.

Ovarian function in captive owl monkeys (Aotus nancymaae and A. vociferans)

Ovarian function and morphology of owl monkeys (Aotus spp.) is inadequately known, but it is essential to describe this organ in detail to better understand reproductive patterns of the species.
