Avian Dermatology

Chapter 170 Avian Dermatology



Skin and feather disorders are common in companion avian species. Since many of these disorders have a psychological basis, either as the primary cause or as a contributing component, diagnosis and treatment can often be frustrating. A detailed history, physical examination, and assessment of a wide range of diagnostic tests are generally required for diagnosis.





GENERAL HISTORY AND EXAMINATION





DISORDERS OF THE SKIN AND SUBCUTANEOUS TISSUES



Infectious Diseases



Ectoparasites



Knemidokoptes pilae (Scaly Leg and Face Mites)









Viral Diseases






Bacterial Diseases


Primary bacterial skin infections are uncommon. Most infections are secondary to trauma, including selfmutilation or other disease processes. The low incidence of primary pyoderma is thought to be due to high body temperatures and keratinocyte-derived lipids that inhibit bacteria growth.



Bacterial Folliculitis







Chronic Ulcerative Dermatitis


This syndrome is characterized by ulceration, hyperemia, feather loss, and self-mutilation in a localized area of the dermis. Lesions may be seen alone or may be associated with other diseases.









Neoplasia


Cutaneous neoplasms occur with relative frequency in companion birds. Most diagnostic and treatment protocols have been extrapolated from mammalian medicine. Refer to the corresponding chapters on mammalian neoplasia for details (see Section 3).
