Dirofilaria repens in a dog imported to Denmark: A potential for emerging zoonotic disease.

Dirofilarosis is spreading among dogs and humans in Europe with infections being established in many countries. Here, we describe the first molecular biologically confirmed case of D. repens infection in an imported dog in Denmark and highlight the potential zoonotic aspects from this emerging zoonotic parasite in central and northern Europe as at least one to two generations of Dirofilaria spp. can occur per year in Denmark.
