Date of origin of the SARS coronavirus strains
BACKGROUND A new respiratory infectious epidemic, severe acute respiratory syndrome (SARS), broke out and spread throughout the world. By now the putative pathogen of SARS has been identified as a new coronavirus, a single positive-strand RNA virus. RNA viruses commonly have a high rate of genetic mutation. It is therefore important to know the mutation rate of the SARS coronavirus as it spread...
متن کاملUltrastructure and origin of membrane vesicles associated with the severe acute respiratory syndrome coronavirus replication complex.
The RNA replication complexes of mammalian positive-stranded RNA viruses are generally associated with (modified) intracellular membranes, a feature thought to be important for creating an environment suitable for viral RNA synthesis, recruitment of host components, and possibly evasion of host defense mechanisms. Here, using a panel of replicase-specific antisera, we have analyzed the earlier ...
متن کاملDemography and the Coronavirus Pandemic
Abstract. One of the most urgent policy issues related to the COVID-19 pandemic in Europe concerns the extent and ways in which demographics have determined different patterns of mortality between groups and regions, and whether and how the pandemic and its economic consequences will affect population dynamics in the future. Post-pandemic policy evaluations on the spread of COVID-19 and the im...
متن کاملEvidence for a common evolutionary origin of coronavirus spike protein receptor-binding subunits.
Among different coronavirus genera, the receptor-binding S1 subunits of their spike proteins differ in primary, secondary, and tertiary structures. This study identified shared structural topologies (connectivity of secondary structural elements) in S1 domains of different coronavirus genera. The results suggest that coronavirus S1 subunits share a common evolutionary origin but have attained d...
متن کاملAntigenic relationships among proteins of bovine coronavirus, human respiratory coronavirus OC43, and mouse hepatitis coronavirus A59.
Antisera prepared against each of three single and one pair of major structural proteins of the bovine coronavirus (Mebus strain) were used in immunoblotting studies to measure cross-reactivity with the structural proteins of the human coronavirus OC43 and the mouse hepatitis coronavirus A59. We conclude that the bovine coronavirus is comprised of four major structural proteins, gp190 (normally...
