Influenza A and B viruses in allantoic fluid can be adsorbed by certain grades of diatomaceous earths usually employed as filter aids, there being a marked degree of correlation between the 'flow rate' of the earths and their ability to adsorb the virus.

Neurovirulence of influenza A virus
Journal of Neurovirology, 1996Infection of mouse brain with influenza A virus has provided a valuable model for investigating viral adaptation and virulence. These studies have indicated important roles for the neuraminidase (NA), matrix (M), non-structural (NS) and haemagglutinin (HA) genes of the virus in determining neurovirulence.

Cell, 1977
In 1931 influenza viruses were first isolated from pigs (Shope, 1931), and subsequently the first human influenza virus isolates were obtained (Smith, Andrewes, and Laidlaw, 1933). This marked the beginning of modern influenza virus research, and from then on many scientists have been fascinated by this virus and the disease it causes. Unlike any other

The laboratory diagnosis of influenza uses a wide range of techniques including rapid immunoassays, immunofluorescence techniques, virus culture methods, and increasingly sophisticated molecular assays. The potential utility of each of these methods has changed over the years, most dramatically perhaps with the emergence of the pandemic H1N1 2009 ...

Veterinary Clinics of North America: Equine Practice, 2014
For decades the horse has been viewed as an isolated or "dead-end" host for influenza A viruses, with equine influenza virus being considered as relatively stable genetically. Although equine influenza viruses are genetically more stable than those of human lineage, they are by no means in evolutionary stasis.

Influenza A Virus Reassortment
2014Reassortment is the process by which influenza viruses swap gene segments. This genetic exchange is possible due to the segmented nature of the viral genome and occurs when two differing influenza viruses co-infect a cell. The viral diversity generated through reassortment is vast and plays an important role in the evolution of influenza viruses ...

Influenza Virus Endoribonuclease
2001The influenza virus polymerase complex contains two associated enzymatic activities, an endoribonuclease and a RNA-dependent RNA polymerase activity. Both activities have so far been observed only with the complete polymerase complex consisting of three subunits, PB1, PB2, and PA.

The Genome of the Influenza Virus
1978Burnet and his colleagues (1949) were the first to recognize an unexpectedly high frequency of recombination among different strains of influenza A viruses (for a review of this work see Burnet, 1959). These studies were confirmed and extended by Simpson and Hirst (1961), taking advantage of the plaque technique, which became available for influenza ...

As a major pathogen of human and certain animal species, influenza virus causes wide spread and potentially devastating disease. To initiate infection, the virus first binds to cellular receptors comprising either -(2,3 ) or -(2,6) linked sialic acid. Recent advances in our understanding of the influenza virus receptor and viral host species involved ...
