This book contains talks and poster information from a 1994 international symposium on coronaviruses. The purpose is to provide reviews and updates of recent scientific advances in this important field. The book is targeted for scientific or clinical investigators in virology, infectious diseases, molecular biology and genetics, and pharmaceutical personnel. Clear, succinct updates and reviews by leading investigators in the field make this an important contribution. This is an excellent update/review for serious students or investigators interested in the virology, immunology, and infectious disease aspects of this important group of viruses. These viruses include many human and veterinary pathogens of great economic importance. Remarkable advances in understanding the genetics and basis of resistance, the immune responses elicited, and the pathogenesis of infections by these viruses are clearly conveyed by leaders in the field in this symposium proceedings.
