DISRUPTION OF INFLUENZA VIRUS

Disruption of Influenza Virus

1. The hemagglutinating capacity, enzymic activity, and infectivity of several influenza viruses were destroyed by repeated freezing and thawing of dialyzed allantoic fluids containing them. 2. Influenza virus degraded by freezing and thawing, by treatment with 5 M urea, or by heating at 65 degrees C. still combined with homologous antibody and was demonstrable by blocking of the hemagglutinati...

Disruption of Influenza Virus Properties of Degradation Products of the Virus Particle

Two different precipitating antigens have been extracted from vaccinia virus. One, designated the LS antigen (1), is a protein with two antigenically active groups (2, 3); the other, termed the NP antigen, is a nudeoprotein (4). These two antigens apparently comprise a large proportion of the mass of the virus particle. The soluble complement-fixing antigen of influenza virus is usually extract...

2009 H1N1 Influenza Virus Seroepidemiology

Isolation and Identification of Avian Influenza Virus H9N2 Subtype

Design, Production, and Evaluation of Virosomes from H1N1 Influenza Virus

Background: The last two decades witnessed the spread of the first generation of influenza viruses. Influenza virosomes are promising tools in vaccine and immunotherapy programs because of their applications in various medical fields. The aim of the present study was to construct cationic virosomes derived from influenza virus using dialyzable detergent (DCPC) and cationic lipid (DOTAP) in vit...
