Retrospective study on the presence and pathogenicity of Dirofilaria repens in 5 dogs and 1 cat from Aosta Vally.
Aosta Valley is the only region of Italy free of reported human cases of dirofilariosis due to Dirofilaria repens. Nonetheless, the retrospective analysis of five locally acquired D. repens infections in dogs, seems to indicate that an animal reservoir exist in the area. A feline case imported from Camargue, France, is also described. The most common dermatological signs were erythema, alopecia, crusting, papulae and nodules. All patients had lesional pruritus and dogs were affected by concurrent babesiosis. Eradication of the underlying condition, followed by a therapy with the specific adulticide and microfilaricide drugs led to a complete recovery of microfilaraemia. Increased pet travel and ecological changes are extending the ranges of vector borne, parasitic and zoonotic diseases. This fact pose a unique diagnostic challenge for the veterinarian, since the index of suspicion may be absent outside endemic areas.
