Plain-English summary
In a study from Aosta Valley, Italy, researchers looked at infections caused by a parasite called Dirofilaria repens in five dogs and one cat. Although this region has not reported any human cases of this infection, the findings suggest that local animals can carry the parasite. The dogs showed skin problems like redness, hair loss, scabs, and bumps, and they were also very itchy. Additionally, the dogs had a co-existing infection called babesiosis, which is caused by a different parasite. After treating the underlying issues and using specific medications to kill the adult parasites and their larvae, all the pets fully recovered.
Abstract
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.
