Virology

Virology is a knowledge that study of viruses and virus-like agent or viruses history. This material include of viruses structure, viruses classification and evolution, the way of viruses to infect other creature and then exploit host cell that use for virus reproduction. Virology also study of the diseases that causes, the technique to isolate and culture them, and their use in research and therapy.

Because of the large discussion of viruses, this material often discuses on other subject and often become a parts of microbiology and pathology. The structure of viruses can be changed depend to the host of cell they infect, like animal viruses, plant viruses, fungal viruses and bacteriophages (viruses infecting bacteria, which include the most complex viruses).

If bacteria size still using of micron, viruses have size in smaller range about 30 nm to about 450 nm, this is a very very small size range. Micro size is one per million meter, and nano meter is one per thousand million meters. So a creature with thousandth time of bacteria can infect them. If infect human then this will very very small compare to human cells.

If viruses infect to human cell then virus will become of part of cells, some time unite with human DNA, this is a part of human cell. DNA can change the base structure of human DNA and a bad effect of this DNA character can derivate to the next human.

Because of nano size the technology to kill this viruses should use nano technology, many expert have use other viruses to kill viruses, of build body immune to kill this viruses. Virology that using of nano technology always develop and may on the next generation will available of nano medication to kill this infected viruses.
