Zoonotic Onchocerca lupi Infection in Dogs, Greece and Portugal, 2011-2012

Onchocerca lupi infection is reported primarily in symptomatic dogs. We aimed to determine the infection in dogs from areas of Greece and Portugal with reported cases. Of 107 dogs, 9 (8%) were skin snip positive for the parasite. DNA sequences of parasites in specimens from distinct dog populations differed genetically from those in GenBank.
