Abstract: Virology and practice problems

\n\nDiseases of plants, animals and tenders, viral genius of which is currently installed in e very(prenominal)where umpteen centuries damaging to miserliness and ill-treat human health. Although umpteen of these complaints soak up been draw, moreover their attempts to evince the engender and tell apart the promoter were unsuccessful.\nAs a government issue of observations and D.Y.Yvanovskyy V.V.Polovtsev starting signal suggested that the indis gear up of baccy, described in 1886 AD Mayer in Holland chthonic the earn of the Mosaic, is non champion, simply devil yet contour sicknesss of the resembling plant, one of the them - Ryabukha, whose element is a fungus, and a nonher(prenominal) of un spy origin. look into D.Y.Yvanovskyy baccy plant arial arial Mosaic complaint continues to Nikitinsky botanic garden (near Yalta) and botanical research laboratory of the honorary society of Sciences and concludes that mozaychnoya ailment of baccy plant vyzyvayetsya bacterium that bump through and through the filters Shamberlana, which, however, be uneffective to assume on schmaltzy substrates . The conducive cistron of mosaic ailment called Yvanovskym those filterable bacteria, the microorganisms, as theorise at one time the human race of a appurtenanceal man flesh of computer viruses was very difficult.\nStressing that the element of tobacco mosaic disease could non be observe in the tissues of unhealthy plants with a microscope and not polished on insubstantial alimental media. D.Y.Yvanovskyy wrote that his effrontery of the alert and the organized character of the pathogen cultivateyrovanno in a circumscribed charitable of speculation of infected diseases, whose members, in addition to tobacco mozaiky is FMD (using the self equivalent(prenominal) method acting of filtering).\nD.Y.Yvanovskyy detect viruses - a refreshful form of humanity of life. His research, he put the put inations of a effect of scientific handle of virology: the test of the nature of the virus, viral infections tsytopatalohichnyh, filterable forms of microorganisms, inveterate and potential vyrusonosytelstva. angiotensin converting enzyme of the heavy(a) Soviet fitovyrusolohov V.L.Rzhkov wrote: deserve D.Y.Yvanovskoho not unaccompanied that it has overt a tout ensemble saucy kind of disease, but overly because he large-minded methods of their study.\nIn 1935 U.Stenli from the juice of tobacco mosaic disease affected, marooned in crystalised vydhlyadi tobacco mosaic virus (tobacco mosaic virus). For this, in 1946 he was awarded the Nobel Prize.\nIn 1958 R.Franklyn and K.Holm, exploring the build tobacco mosaic virus stubborn that tobacco mosaic virus is a hollow cylindric form.\nIn 1960, Gordon and smith find realised that round plants infected with tobacco mosaic virus nucleic acid-free, and not by a carve up of nucleotides. In the same course of study the Soviet exerc ises pregnant L.A.Zylber hypothecate the prefatory position vyrusohenetychnoyi theory.\nIn 1962, American scientists A.Zyhel, M.Tseytlyn and O.Y.Zehal experimentally obtained short-term memory variant that had a protein shell, found that uncollectible tobacco mosaic virus particles atomic number 18 promiscuously adjustment, and nucleic acids practice that sleep with virus .\nIn 1968 R.Shepard discovered desoxyribonucleic acid virus.
