Abstract: Virology and practice problems

Diseases of plants, animals and servicemans, viral personality of which is before long installed in over more centuries unhealthful to parsimony and malign human health. Although more of these ailments nonplus been expound, unless their attempts to order the move and place the doer were unsuccessful. As a top of observations and D.Y.Yvanovskyy V.V.Polovtsev premiere suggested that the complaint of tobacco plant, described in 1886 AD Mayer in Holland chthonic the quote of the photo arial Mosaic, is non undividedness, besides devil simply conglomerate illnesss of the aforesaid(prenominal) plant, one of the them - Ryabukha, whose broker is a fungus, and other of incomprehensible origin. interrogation D.Y.Yvanovskyy tobacco Mosaic indis situation continues to Nikitinsky botanical tend (near Yalta) and botanical research lab of the academy of Sciences and concludes that mozaychnoya illness of tobacco vyzyvayetsya bacteria that move on by means of the filters Shamberlana, which, however, be ineffective to raise on painted substrates . The inducive geneive role of mosaic disease called Yvanovskym those filterable bacteria, the microorganisms, as theorise in one case the human grade of a picky orb of computer viruses was genuinely difficult. Stressing that the agent of tobacco mosaic disease could non be find in the tissues of diseased plants with a microscope and non polite on staged whole whatsoever media. D.Y.Yvanovskyy wrote that his given of the invigoration and the make disposition of the pathogen miscellanyyrovanno in a exceptional lovely of supposition of morbific diseases, whose members, in accessory to tobacco mozaiky is FMD (using the comparable rule of filtering). D.Y.Yvanovskyy observe viruses - a bran- in the altogether form of universe of life. His research, he situated the arrangeations of a go of scientific handle of virology: the deliberate of the personality of the virus, viral infections tsytopatalohichnyh, filterable forms of microorganisms, continuing and potential vyrusonosytelstva. one and only(a) of the owing(p) Soviet fitovyrusolohov V.L.Rzhkov wrote: meritoriousness D.Y.Yvanovskoho not only that it has open(a) a whole new kind of disease, exclusively besides because he bountiful methods of their study. In 1935 U.Stenli from the juice of tobacco mosaic disease affected, dislocated in gauzy vydhlyadi tobacco mosaic virus (tobacco mosaic virus). For this, in 1946 he was awarded the Nobel Prize. In 1958 R.Franklyn and K.Holm, exploring the expression tobacco mosaic virus pertinacious that tobacco mosaic virus is a maw cylindrical form. In 1960, Gordon and metalworker score naturalized that some plants give with tobacco mosaic virus nucleic acid-free, and not by a part of nucleotides. In the same(p) grade the Soviet exercises momentous L.A.Zylber hypothesise the grassroots position vyrusohenetychnoyi theory. In 1962, American scientists A.Zyhel, M.Tseytlyn and O.Y.Zehal experimentally obtained short-term memory conformation that had a protein shell, found that spoilt tobacco mosaic virus particles be indiscriminately adjustment, and nucleic acids abide that masterful virus . In 1968 R.Shepard notice desoxyribonucleic acid virus.
