Additional Information:
|
NR-44006 is an engineered recombinant coronavirus based on a full-length infectious clone of the SARS-CoV, Urbani genome. SARS-CoV, Urbani was serially passaged in the lungs of BALB/c mice fifteen times, and biological clones from lung homogenates were screened for lethality. One clone, MA15, which was 100% lethal in BALB/c mice within six days of inoculation, was sequenced. Six coding mutations associated with mouse adaptation and increased virulence were identified and inserted into cDNA clones that were used to construct and rescue an infectious recombinant mutant clone of SARS-CoV, Urbani. The recombinant virus was highly virulent and lethal, reproducing the phenotype of the biologically derived MA15.1,2
