The goal of this work is to present the reader with the most common diseases that can produce immunosuppression in poultry, provide guidance for the diagnosis of immunosuppressive diseases, and examine the challenges that a diagnostician may face in confirming a diagnosis of immunosuppression. The book will feature an extensive collection of color photographs depicting the gross and microscopic images.
