Interference between the Influenza Viruses
Influenza A or influenza B virus rendered non-infective by ultraviolet radiation was found to be capable of producing interference with the multiplication of active influenza viruses in the chick embryo. Certain temporal and quantitative relationships affecting the interference phenomenon with this host-virus system were studied. An hypothesis of the mechanism of interference between the influe...
متن کاملThe isolation of influenza viruses.
Of 129 strains of the Hong Kong variant of influenza A2 virus isolated from 176 respiratory infections, 105 (81.4%) were isolated in tissue culture, the remainder being detected only by the inoculation of fertile hen's eggs. Organ cultures of chick embryo trachea were at least as sensitive as monkey kidney tissue culture for the isolation of this virus but organ cultures of human embryonic cili...

I n the preceding paper exper iments were described on the effect of in t racerebral inject ion of influenza virus prepara t ions . Convulsions were no ted in mice within 24 to 7.2 hours and occasionally later , wi thout demonst rable propagat ion of the agents in the central nervous system. I t was concluded tha t the influenza viruses m a y exert toxic effects on an organ which usual ly does ...
متن کاملFilamentous influenza viruses.
Clinical isolates of influenza virus produce pleomorphic virus particles, including extremely long filamentous virions. In contrast, strains of influenza that have adapted to laboratory growth typically produce only spherical virions. As a result, the filamentous phenotype has been overlooked in most influenza virus research. Recent advances in imaging and improved animal models have highlighte...
