Studies on herpes simplex virus. I. The stability and preservation of egg-adapted herpes simplex virus.
In animal tissues the virus of herpes simplex is very stable and can be preserved at refrigerator temperature or in the frozen state for many months. Egg-adapted herpes virus, on the other hand, is said to be relatively unstable so that it cannot be satisfactorily preserved and stored (Scott, 1948a,b). Two recent standard texts on viruses state that "egg virus appears harder to keep, very littl...

متن کاملDevelopment and Sequence Analysis of a Cold-Adapted Strain of Influenza A/New Caledonia/20/1999(H1N1) Virus
Background and Aims: Vaccination is the most effective method to prevent influenza infection. Among the available vaccines, cold-adapted live-virus vaccines are suitable approach that have been produced and evaluated for recent years in few countries. The goal of this project was to derivate a cold adapted variant of the influenza A/New Caledonia/20/1999(H1N1). Materials and Methods: Influenza ...
متن کاملCold-adapted variants of influenza virus A. I. Comparison of the genetic properties of ts mutants and five cold-adapted variants of influenza virus A.
The genetic properties of seven cold-adapted variants of influenza virus A were compared with those of nine Lfluorouracil (5-FU)-induced ts mutants. The 5-FU mutants had previously been placed into seven complementation-recombination groups; five of the seven cold-adapted variants also had the ts phenotype, and all five were shown to share the group 1 lesion. Three of the cold variants also had...
متن کاملA question of self-preservation: immunopathology in influenza virus infection.
Influenza A viruses that circulate normally in the human population cause a debilitating, though generally transient, illness that is sometimes fatal, particularly in the elderly. Severe complications arising from pandemic influenza or the highly pathogenic avian H5N1 viruses are often associated with rapid, massive inflammatory cell infiltration, acute respiratory distress, reactive hemophagoc...
