<i>Onchocerca lupi</i>Nematodes in Dogs Exported from the United States into Canada

Abstract

The Onchocerca lupi nematode is an emerging helminth capable of infecting pets and humans. We detected this parasite in 2 dogs that were imported into Canada from the southwestern United States, a region to which this nematode is endemic. We discuss risk for establishment of O. lupi in Canada.
