Research: SARS-CoV-2 spike gene passaged in black rats

Hexapeptide vocabularies of the SARS-CoV-2 spike gene showed the shortest immunological T-distance to black rats.

Here we used a new method to search for the original host of the ancestor of the SARS-CoV-2 virus and for the donor of its gene for the spike protein, the molecule responsible for binding to and entering human cells....More...

Preprint: Increasing frequency of cryptic SARS-CoV-2 lineages in New York sewers

Here we report detecting increasing frequencies of novel cryptic SARS-CoV-2 lineages not recognized in GISAID’s EpiCoV database. These lineages contain mutations that had been rarely observed in clinical samples, including Q493K, Q498Y, E484A, and T572N and share many mutations with the Omicron variant of concern....More...
