The first volume to cover the entire nidovirus order, including arteriviruses, toroviruses, roniviruses, and several recently identified human coronaviruses. * Provides crucial information for researchers in virology, epidemiology, biochemistry, cell biology, pathogenesis, and antiviral drug development. * Synthesizes the most recent research on the basic microbiology of nidoviruses, their genetic replication, and immune system responses. * Addresses the impact of the recently developed systems for nidovirus reverse genetics, the unique mechanism of nidovirus RNA synthesis, virus-host cell interactions, emerging nidovirus infections, and potential targets for therapeutic interventions. * Serves as essential reading for specialists and for those interested in viral replication and pathogenesis. This title is published by the American Society of Microbiology Press and distributed by Taylor and Francis in rest of world territories.
