Writing primarily for veterinary surgeons, Day (veterinary pathology, U. of Bristol) proceeds from basic immunological principles to their application in the diagnosis and treatment of immune-mediated diseases of the dog and cat. Most chapters are systems-based and discuss hematological, skin, musculoskeletal, neurological, respiratory, endocrine, renal, reproductive, and ocular diseases. Other chapters discuss multisystem diseases, immunodeficiencies, and immune system neoplasia.
