Endoparasites of the coyote (Canis latrans), a recent migrant to insular Newfoundland

Abstract

This study provides the first data on the helminth fauna of the coyote (Canis latrans) in insular Newfoundland. Sixty-nine coyotes were collected between 200.1. and 2003 and examined for helminths. A total of 10 helminth species were recorded: the cestodes Taenia ovis krabbei (9%), Taenia hyelatigena (4%), Taenia 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. cemis, and C. vulpis were more prevalent in juveniles than adults. Angiostrongylus vasorum is reported in coyotes for the second time in Newfoundland, Canada. © Wildlife Disease Association 2009.
