  • While the pithovirus, which had been frozen for some 30,000 years before the experiment, is harmless to humans, Professor Claverie said it demonstrates that long-frozen viruses can 'wake up' and begin re-infecting hosts. (dailymail.co.uk)
  • This, combined with the relatively small numbers of seed each soybean plant produces, makes it extremely challenging to generate mutant seed libraries that cover even 50% of genes. (researchsquare.com)
  • Orthopoxviruses and Monkeypox virus were detected in the organs by PCR using consensus primers targeting the virus surface membrane haemagglutinin (HA) genes, while Leptospira species were detected by PCR using primers targeting the rrs and lfb1 genes. (bvsalud.org)
  • There are vaccines and antibodies to combat the virus, but don't be fooled! (plantsentry.com)
