Studies on the Toxicity of Influenza Viruses
Intracerebral injection of preparations of influenza viruses into mice led to tonic and clonic convulsions and death in tetanus, usually within 24 to 72 hours. Histological examination revealed the destruction of the ependymal lining of the ventricles as the dominant finding. These reactions were obtained in four different strains of mice as well as in rats, guinea pigs, and hamsters. They were...

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 کاملGenetic Studies of Influenza Viruses
The passage of newly isolated, filamentous Asian (A2) influenza viruses in the presence of non-infective PR8 (A) virus results in the rapid emergence of virus of Asian (A2) antigenicity but PRS-like growth capacity and spherical morphology. Evidence is presented that this effect results from genetic interaction of the infective Asian and non-infective PR8 viruses rather than from spontaneous ch...
متن کاملStudies on the P-Q variation of influenza A2 viruses.
3) Heat stability of hemagglutinins is higher with Q virus than P virus. 4) Bovine red cell agglutinins are detectable only with Q virus but not with P virus. In this article, the fact that the activity of receptor destroying enzyme is higher with Q virus than when P virus was added as the fifth marker. In the second place, higher avidity of P virus than Q virus to immune sera was studied furth...
متن کاملSerological Studies of Swine Influenza Viruses
1. Cross-neutralization tests with sera from swine recovered from infection with swine influenza indicated the serological identity of 7 strains of swine influenza virus obtained from different sources. 2. Cross-neutralization tests with sera from rabbits, immunized to swine influenza virus, exposed serological differences among the same 7 swine influenza virus strains. Two strains appeared to ...
