Introduction to Modern Virology, an established student text for over 25 years, has been fully revised and updated in this fifth edition. Providing an integrated account of animal, plant and bacterial viruses, this book covers the field of virology from molecular biology to disease processes. Topics include the molecular aspects of virion structure, virus entry, replication and gene expression of RNA and DNA viruses and the classic paradigm of lysogeny. On the biomedical side, chapters deal with virus cultivation, immunology and carcinogenesis. Human and animal virus diseases are dealt with generically within the text, bringing all infections within a highly manageable seven-section framework. Prevention and therapy, evolution and emerging viruses receive particular attention and specific chapters address the major infectious challenges posed by HIV, pandemic influenza and BSE. This highly accessible new edition provides ideal reading for all undergraduate and postgraduate students of biology and medicine wishing to study virology.
