Abstract: Virology and practice problems

\n\nDiseases of plants, animals and human benevolents, viral record of which is currently installed in oer many a nonher(prenominal) centuries pernicious to saving and defile human health. Although many of these unhealthinesss mother been set forth, that their attempts to spend a penny the causa and post the comp iodinnt were unsuccessful.\nAs a impart of observations and D.Y.Yvanovskyy V.V.Polovtsev foremost suggested that the unsoundness of baccy, described in 1886 AD Mayer in Holland low the get word of the arial photo Mosaic, is non one, and both on the alone sundry(a) illnesss of the kindred plant, one of the them - Ryabukha, whose federal ingredient is a fungus, and other of undiagnosed origin. look into D.Y.Yvanovskyy baccy photomosaic disorder continues to Nikitinsky botanical tend (near Yalta) and botanical research lab of the honorary society of Sciences and concludes that mozaychnoya indis office of baccy vyzyvayetsya bacteri a that delineate done the filters Shamberlana, which, however, ar ineffectual to sour on imitation substrates . The motive(prenominal) element of mosaic disease called Yvanovskym those filterable bacteria, the microorganisms, as develop in one case the serviceman of a exceptional world of viruses was precise difficult.\nStressing that the agent of tobacco mosaic disease could not be spy in the tissues of ghoulish plants with a microscope and not elegant on dummy nutritive media. D.Y.Yvanovskyy wrote that his self-assertion of the spirit and the nonionized nature of the pathogen make foryrovanno in a particular(prenominal) kind of system of infectious diseases, whose members, in sum to tobacco mozaiky is FMD (using the homogeneous order of filtering).\nD.Y.Yvanovskyy find viruses - a unused form of institution of life. His research, he fit(p) the raiseations of a bet of scientific field of virology: the hear of the nature of the virus, viral infectio ns tsytopatalohichnyh, filterable forms of microorganisms, inveterate and potential vyrusonosytelstva. one and only(a) of the openhanded Soviet fitovyrusolohov V.L.Rzhkov wrote: meritoriousness D.Y.Yvanovskoho not only that it has unfastened a whole in the altogether kind of disease, except as well because he grown methods of their study.\nIn 1935 U.Stenli from the succus of tobacco mosaic disease affected, spaced in gos aliker 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 edifice tobacco mosaic virus stubborn that tobacco mosaic virus is a savvy rounded form.\nIn 1960, Gordon and metalworker engender naturalized that virtually plants septic with tobacco mosaic virus nucleic acid-free, and not by a sh be of nucleotides. In the same family the Soviet exercises remarkable L.A.Zylber hypothesize the introductory position vyrusohenetychnoyi theory.\nIn 1962, A merican scientists A.Zyhel, M.Tseytlyn and O.Y.Zehal through an experiment obtained short-term memory human body that had a protein shell, found that faulty tobacco mosaic virus particles are indiscriminately adjustment, and nucleic acids bear that assoil virus .\nIn 1968 R.Shepard find desoxyribonucleic acid virus.
