SummaryIn horses, allergic disease has been implicated in the pathophysiology of atopic dermatitis, recurrent urticaria, and recurrent airway obstruction. With the present study, it is aimed to give information about allergens which determined in Thoroughbred stallions with detecting serum IgE. 18 Thoroughbred stallions averaged 11 years old were included in the study. Fifteen single and five mix allergens were checked for allergen-specific IgE. English plantain (Plantago lanceolata), Birch/Alder/Hazel and Micropolyspora faeni/Thermoactinomyces were detected as quite allergic to six Thoroughbred stallions at total. Consequently, assays detect equine IgE, can be an effortless method in determining allergens in horses.

Bu çalışma ile İngiliz aygırlarında serum spesifik IgE tespiti ile alerjenlerin tayini hakkında bilgi verilmesi amaçlanmıştır. Yaşları ortalama 11 olan, 18 İngiliz aygır çalışma materyalini oluşturmuştur. On beş tek ve beş karışık alerjene serum spesifik IgE yönünden bakılmıştır. Toplam altı İngiliz aygırda English plantain (Plantago lanceolata), Birch/Alder/Hazel ve Micropolyspora faeni/Thermoactinomyces oldukça alerjik olarak tespit edilmiştir. Sonuç olarak, atlara özgü IgE'yi belirleyen serolojik testler alerjenlerin tespiti bakımından zahmetsiz bir yöntem olarak değerlendirilebilir.

It is aimed to detect allergen determination via serum specific immunoglobulin E (IgE) for the first time in dogs diagnosed as Atopic Dermatitis (AD) from Samsun and vicinity within this present study. Twenty one dogs with different age, breed and gender diagnosed with AD based up on the Favrot's criteria. Serum samples of the dogs were analyzed by detection of serum specific IgE for determination of 20 different allergens. The effects of gender, age and the feeding routes for those 20 different allergens separately were analyzed. Based up on the grading of the allergens detected in 21 dogs with AD from Samsun and vicinity; results reflects that Dermatophagoides farinae was stated as first degree within a very high seropositivity rate (95%). Moreover, in varying degree of seropositivitiy rates of other allergens were also detected. Females showed statistically (p<0.05) higher positivity rate to the 20 th allergen, Ctenocephalides spp. more than males. Furthermore, we did not found any significant effects of age and feeding routes on the allergens in the dogs with AD (p>0.05). Dogs with AD from Samsun and vicinity had very high serum specific IgE levels against to the house dust and storage mites.
