Coronavirus pathogenesis and the emerging pathogen severe acute respiratory syndrome coronavirus

Article Abstract:

The pathogenesis of the previously known coronation viruses, the contribution of individual viral genes to tropism and pathogenic phenotype are discussed along with the roles of individual coronavirus genes in infection. Reverse genetics technology has advanced the understanding of coronaviruses and both mutant, chimeric recombinant viruses are used in investigation of the roles of spike and other proteins in coronavirus replication and pathogenis.
