The Herpesviruses provides information pertinent to all the herpesviruses, with emphasis on the classification, morphology, replication, physical–chemical properties, and immunological relationships of all the herpesviruses. This book presents the fundamental and clinical aspects of the viruses. Organized into 21 chapters, this book starts with an overview of the classification of the herpesvirus and proceeds to explore the origins and phylogeny of the herpesviruses. This text then examines the earliest electron microscopic studies on the morphology of the herpesviruses by using shadowcast preparations of herpes simplex virus and of herpes zoster virus. Other chapters consider the serological tests as well as the antigenic relationships among herpesviruses. The final chapter deals with the clinical application of antiviral drug treatment. This book is a valuable resource for virologists, molecular biologists, veterinarians, physicians, as well as teachers and graduate students who are interested in the herpesviruses from either a fundamental or clinical viewpoint.
