Virusses

In the cases which have been cited to prove the identity of the two virusses, it has been said that a diseased individual having had connection with several healthy persons, these latter would be variously affected; some would have chancres, some gonorrhœa, and others both together.

In recent times the question of the origin of life is connected with the problem of the living or non-living character of the virusses.

but it was only in recent years that it was discovered that certain organisms, namely virusses, are responsible for this degeneration. Leafroll is caused by a single virus, while most of the mosaic diseases are caused by one of the X, Y or A virusses.

These protein-like substances are very efficient in neutralising virusses, but are present in small numbers for a relatively short period of time.

Next we recapitulate some basic facts on liquid crystals. The building blocks of these materials are anisotropic particles, e.g., elongated molecules, associated structures such as wormlike micelles, or even rodlike virusses.

Rightside-out plasma membrane derivatives can be obtained by making use of specific virusses. Enveloped virusses such as the influenza virus (Lenard and Rothman, 1976) and Semliki Forest Virus (Van Meet et al., 1981) bud through the plasma membrane of the host cell and obtain this way their lipid bilayer directly from the host cell plasma membrane.

Computer virusses are programs which can self-replicate and propagate via digital media. Prior to the Internet becoming commonplace, the common medium was the floppy disc. Nowadays virusses are passed over the Internet.
