Organized by body system, the new edition of this highly illustrated textbook covers the normal histological appearance of tissues in a wide range of animals, both domestic and exotic species, with relevant clinical correlates emphasizing the need to appreciate the normal in order to recognize the abnormal. In this update by two experienced veterinary pathologists and histology lecturers, new species, such as other companion mammals, aquatic species and livestock, are introduced into each chapter along with a wealth of new high-quality images. A new chapter covers epitehlial tissue and new techniques used in histology and histopathology are discussed throughout, including ISH and digital image analysis. Pathogenesis explanation is introduced in the current (and many new) cases of histopathology. The breadth of coverage--farm animals, dogs, cats, horses, birds, reptiles, amphibians, and fish--and the integration of normal and abnormal tissue provide a reference of lasting value to veterinary students as well as veterinary practitioners and pathologists needing a quick refresher.
