| Abstract: | A pruritic dermatitis characterized by the presence of erythema, papules, focal or multifocal alopecia, crusting and nodules was seen in 28 dogs with Dirofilaria repens microfilariae infestation in an endemic area in north-west Italy. Previous unsuccessful nonspecific antipruritic treatments, flea control and restricted diet were recorded in 53.6% of the patients. Both the Knott and the antigen tests were negative for Dirofilaria immitis and Acanthocheilonema reconditum. Concurrent babesiosis and/or canine granulocytic ehrlichiosis was also diagnosed in many affected dogs. Preliminary treatment of the concurrent diseases was followed by specific filaricide treatment. The cutaneous lesions, although slightly improved with the initial treatment, resolved completely with macro- and microfilaricide treatment. Although D. repens may be an opportunistic pathogen, this parasite should not be considered as harmless as previously thought and its potential pathogenic role in causing cutaneous lesions in dogs should be considered. Furthermore, it has a zoonotic importance as human cases have been reported worldwide. |
