Dietary and other allergies in animals

Allergies are currently problems not only people, alsomostly animals.This bachelor thesis is mainly focusing on a few selected allergies and their symptoms, which are occuring in animals. Firstly, the basic concepts of alergology isdescribed along with anature and emergence of allergies. An allergy can beunderstoodas an immune response of the organism to antigens, which come from an external environment. They couldoriginate from inhalation, contact, insect or drug allergens. There are four known types of hypersensitivity reactions. Secondly, the thesis focuses on the explanation of allergiesdiagnoses, which arecarried out differently according to the type of presumed allergy. Most frequently used are dermaltests followed by dietonesconsisting of nourishment that is without componentsthat might potentially cause food allergies. Clinical signs and symptoms help us to reveal the type of allergy we are dealing with and what is its exact form. Some of those symptoms might be gastrointestinal disorders, respiratory difficulties or skin manifestations of allergies. Further, there will be stated examples of allergies that give difficulties to animals as well as their treatment options. The primary treatment is the removal of the identified allergen from the environment in which the animal lives. If the allergen can not be removed from everyday life, a specific allergen therapy might be the a solution.The method is based on the gradual administration of increasing doses of the antigen into the organism. This ensures a sufficient cumulative dose of allergen inthe body, which causes the alleviation of clinical symptoms, or even the complete disappearance of difficulties in the exposure to the allergen. This desensibilization also referred to as hyposensibilization currently seems to be the best method of treatment, especially for the hypersensitivity reactions.Method of specific allergen therapy shows great results and in the future will certainly be very used. Veterinary doctors and different companies, however, are working on new research related to treatmentof allergies and so it is very likely that not only the method of allergen therapy, but other methods of suppression of symptoms will be in the future replaced by other, better methods of treatment
