In recent years there has been growing international focus on the importance of emerging and re-emerging arthropod-borne diseases in both human and veterinary medicine. Increasingly these diseases are being diagnosed and treated in veterinary practice. In this book the authors first discuss the overall significance of this group of diseases, plus arthropod biology and immunology, and current laboratory diagnostic methods, followed by individual chapters on each disease entity, grouped by causative organism (protozoan, bacterial, viral). Each chapter covers background etiology and epidemiology, including the role of wildlife species and zoonotic effects, pathogenesis, clinical signs, diagnosis and treatment. The book is illustrated throughout in color and contains photographs of clinical cases, hematology, cytology and gross microscopic pathology. The book aims to provide, in a single reference source, an accessible guide to arthropod-borne infectious disease for veterinarians in practice and training.
