![]() The prevalence of allergies was significantly higher-by almost threefold-in cats seropositive for D. The results of testing with the allergen kits showed that 50.8% of cats were seropositive for ≥ 1 allergens, with the most common allergens being Dermatophagoides farinae (25.8%), Dermatophagoides pteronyssinus (20.0%), Malassezia (17.5%) and Ctenocephalides felis (14.2%). immitis IgG and 55 (45.8%) showed clinical signs of heartworm disease of a respiratory nature. Of the 120 cats tested, 72 (60.0%) were seropositive for anti- D. immitis and for hypersensitivity to 20 allergens, using commercial allergen test kits. Methodsīlood samples were collected from 120 cats and tested for the presence of specific immunoglobulin G antibodies against D. immitis present hypersensitivity to some environmental allergens. The aim of the present study was to verify whether cats seropositive for D. ![]() Allergy is a multifactorial pathology, and the role of a number of helminth parasites in the development of allergies in humans and other species has been demonstrated in many studies. Cats can be infected by Dirofilaria immitis, the causative agent of heartworm disease, characterized by respiratory signs, airway hyperreactivity, remodelling and inflammation. ![]()
