Klappentext zu „Genetics of Influenza Viruses “
With the advent of genetic engineering methods and improved biochemical tech niques, much has been learned about the replication of influenza viruses, their structure and their epidemiology. It appears that the time is ripe to review these efforts and to provide a molecular perspective of influenza virology. It is hoped that this book will stimulate our thinking, help us in designing new experiments, and possibly show avenues leading to the control of the diseases associated with influenza viruses.
