Case report of helminths and lung mite infection in the red-tailed monkey, Cercopithecus ascanius schmidti, in Mahale Mountains National Park, Tanzania

Abstract

We documented the presence of gastrointestinal nematodes and lung mites in two red-tailed monkeys, Cercopithecus ascanius schmidti, in Mahale Mountains National Park, Tanzania. We detected lung mites, Pneumonyssus duttoni, in the trachea and bronchioles, and five species of nematodes, Oesophagostomum pachycephalum, Ternidens deminutus, Streptopharagus pigmentatus, Primasubulura distans, and Trichuris sp. in their gastrointestinal tracts. This is the first report of a parasitological survey for the red-tailed monkey in Mahale Mountains National Park, and O. pachycephalum, T. deminutus, and P. distans were found for the first time in the red-tailed monkey.
