Endoparasites of the Coyote (Canis latrans), a Recent Migrant to Insular Newfoundland

This study provides the first data on the helminth fauna of the coyote (Canis latrans) in insular Newfoundland. Sixty-nine coyotes were collected between 2001 and 2003 and examined for helminths. A total of 10 helminth species were recorded: the cestodes Taenia ovis krabbei (9%), Taenia hydatigena. (4%), Taenia pis pisiformis (1%), and Mesocestoides spp. (5%); and the nematodes Toxocara. canis (19%), Toxascaris leonina (1%), Crenosoma vulpis (19%), Physaloptera rara (6%), Uncinaria stenocephala (3%), and Angiostrongylus vasorum (1%). No significant differences (P <= 0.05) were detected between sexes. Mesocestoides spp., T. can-is, and C. vulpis were more prevalent in juveniles than adults. Angiostrongylus vasorum is reported in coyotes for the second time in Newfoundland, Canada.
