Abstract
The fecal examination was carried out on 53 species of captive animals in Kawasaki Yumemigasaki Zoological Park, Kanagawa Prefecture, Japan, between December 2007 and September 2010. As a result, coccidian oocysts and/or nematode eggs were found from about half of animal species, and several fragments of Trichuris ovis (Trichuridae) were found from its feces of moose Alces alces administered with ivermectin.
