Recovery of genetically defined murine norovirus in tissue culture by using a fowlpox v... - 1 views

  • Previous calicivirus reverse-genetics systems have relied on the transfection of either in vitro-transcribed, 5′-capped calicivirus genomic RNA (Chang et al., 2005; Sosnovtsev & Green, 1995) or cDNA constructs, followed by delivery of T7 RNA polymerase using a VACV recombinant (Sosnovtsev et al., 2002; Thumfart & Meyers, 2002). A recent report on rabbit hemorrhagic disease virus (RHDV) has also demonstrated that in vitro-transcribed, uncapped RNA is infectious when transfected into cells or delivered directly to the liver in vivo (Liu et al., 2006). Attempts to recover MNV by using any of these established approaches failed to produce infectious virus (data not shown).
  •  
    This paper contains very good background on the development of the MNV reverse genetics system. The norovirus genome is uncappped, but transfection with uncapped mRNAs does NOT produce many progeny virions.

American Society for Microbiology:Norovirus Disinfection: How Much is Enough? - 0 views

  • wipe with a wet cloth, and then disinfect with chlorine.
  • Household bleach, says Duizer, is an average about 5 percent chlorine when new (concentration declines with age), or 50,000 PPM, and thus, can be diluted 50-fold to achieve the 1,000 ppm.
  • Norovirus is apparently no more resistant to cleaning and disinfection than other pathogens, says Duizer. The virus’ efficiency in causing outbreaks “is more likely due to their extremely low infectious dose
