Viruses are propagated only in living cells, whereby these cells are slain. Often 1 . History The discovery of viruses is attributed to the Russian sage consulting group bacteriologist D. Ivanovski, who in 1892 showed that the symptoms of the T abaksmozaïekziekte could be caused in healthy plants by rubbing with the sap of diseased plants the leaves. The sickening principle could not be removed by filtration of the juice through a bacterial filter. In 1898, these results were confirmed and correctly interpreted by the Delft professor MW Beijerinck, who coined the term virus used for infectious principle, but his view that the 'contagium vivum fluid' (a liquid living vaccine) involved a, shows that he has not thought of the particle nature of viruses. Also in 1898 showed FAJ Löffler and P. Frosch that foot and mouth disease in cattle is caused by a filterable agent, while G. Sanarelli this demonstrated for myxomatosis in rabbits. Many other infectious sage consulting group diseases could then be attributed. To viruses FW Twort (1915) and F. d'Hérelle (1917) reported the existence of specific viruses that use bacteria as a host (see, bacteriophage). In 1935 managed WM Stanley to the tobacco mosaic virus (TMV) to purify sage consulting group and to strongly reduce, until crystallization after which it could be shown that it is a nucleoprotein (nucleic acid, ribonucleic acid, in this case, with the protein). For this virus Then it showed also that viruses filters with very small pores can not pass, while the end of the virus particles could be made. Visible by the application of the electron microscope The philosophical question of whether sage consulting group viruses are alive or dead, is still made, but is usually of semantic nature, involving the meaning of concepts such as 'living' and 'organism'.

Called proto-organisms or viruses. 2 . Structure and composition of each virus has a characteristic structure, size and shape. The size of viruses is between 300 nm (smallpox virus) and approximately 20 nm (parvoviruses, picornaviruses some). The simplest viruses (eg, poliovirus and TMV) contain only 챦 nucleic acid and protein. However, many viruses also contain lipids, as one of the host cell-derived membrane surrounding the nucleoprotein, such as the myxoviruses, herpesviruses, togaviruses, retroviruses, and pox viruses. Carbohydrates are also found (in glycoproteins), while to be at bacteriophages, plant viruses, some animal sage consulting group viruses and polyamines found, that the phosphoric acid groups of the nucleic acids neutralize frequent. In contrast to the living cell can contain only one type of virus nucleic acid. at the plant viruses, this is usually RNA (ribonucleic acid), in a number of cases it is DNA (deoxyribonucleic acid) have been found. The plant virus RNA is usually single-stranded, but double-stranded RNA (eg in wound tumor virus, viruses, fungi) is also observed. The plant virus DNA is found in both a double-stranded form (cauliflower mosaic virus) as well as in a single-stranded form (gemini viruses). The viruses of animals, sage consulting group insects and bacteria contain DNA or RNA. The DNA is usually double-stranded, but some bacteriophages and some animal viruses contain single-stranded DNA. The RNA of these viruses is usually single-stranded, but the double-stranded form and is found inter alia in reoviruses the insect virus cytoplasmic polyhedrosis virus.
