This development has been possible during the last decade due largely to the availability of several model virus-cell systems for experimental study, notably those of the C-type RNA-containing viruses such as Rous sarcoma virus and the small DNA containing viruses such as polyoma and

Rehabilitation — A Topic for Hemophiliacs?In the last few years an increasing number of enzymes were found to be associated with virus particles. For a long time neuraminidase was the only virus specific enzyme known to be an integral part of myxoviruses. Therefore, it is not surprising that it is the best known among the enzymes associated with animal virions.

K. Verm?hlen,H.-H. Brackmann,W. Kalninsecause influenza virus undergoes extreme antigenic variation, the mechanism of which is still poorly understood. Two kinds of antigenic variation occur in influenza viruses, antigenic drift and major antigenic shifts; both involve changes in the hemagglutinin and neuraminidase antigens on the surface of the virus.
