Structural biologist Dr. Marie Pancera led research generating 3D images showing how an antibody blocks the coronavirus spike. They also found an opposite relationship with the fatality rate of a given coronavirus. FACT: The coronavirus disease (COVID-19) is caused by a virus, NOT by bacteria. . Scientists first identified a human coronavirus in 1965. With genome sizes ranging from 26 to 32 kilobases (kb) in length, CoVs have the largest genomes for RNA viruses. Some people who become ill with COVID-19 can also develop a bacterial infection as a complication. An international team of scientists led by the University of Bristol and funded by UK Research and Innovation (UKRI) has found a feature of the SARS-CoV-2 virus that could be used to stop it from infecting human cells. 2020 Apr;92(4):418-423. doi: 10.1002/jmv.25681. The virus that causes COVID-19 is in a family of viruses called Coronaviridae. Coronaviruses are a family of enveloped, single-stranded, positive-strand RNA viruses classified within the Nidovirales order. The total molecular mass is on average 40,000 kDa. There are four main sub-groupings of coronaviruses, known as alpha, beta, gamma, and delta. Coronaviruses (CoVs) are enveloped positive-sense RNA viruses. These spikes latch onto human cells, then undergo a structural change that allows the viral membrane to fuse with the cell membrane. The seven coronaviruses that can infect people are: Science 2005; 309:1864–1868. Now, a group of researchers has figured out the molecular structure of … Rev.
