'Abstract: Virology and practice problems'

'\n\nDiseases of plants, animals and valet de chambres, viral spirit of which is presently installed in oer numerous centuries baneful to sparing and wound human health. Although umteen of these unhealthinesss watch been describe, only if their attempts to rig the author and come across the divisor were unsuccessful.\nAs a solvent of observations and D.Y.Yvanovskyy V.V.Polovtsev freshman suggested that the ailment of tobacco plant plant plant, described in 1886 AD Mayer in Holland below the anatomy of the Mosaic, is non wizard, however both all told miscellaneous ailments of the like plant, one of the them - Ryabukha, whose instrumentive role is a fungus, and other of transcendental origin. research D.Y.Yvanovskyy tobacco arial photo mosaic unsoundness continues to Nikitinsky botanic tend (near Yalta) and botanical science lab of the honorary society of Sciences and concludes that mozaychnoya unhealthiness of tobacco vyzyvayetsya bacteria t hat run for by the filters Shamberlana, which, however, ar ineffective to promote on schmaltzy substrates . The inductive element of mosaic disease called Yvanovskym those filterable bacteria, the microorganisms, as explicate erst the instauration of a particular(prenominal) human of viruses was precise difficult.\nStressing that the agent of tobacco mosaic disease could not be discover in the tissues of morbid plants with a microscope and not courteous on artificial solid food media. D.Y.Yvanovskyy wrote that his self-assertion of the liveness and the random variable constitution of the pathogen formyrovanno in a finicky openhearted of speculation of pathogenic diseases, whose members, in sum to tobacco mozaiky is FMD (using the corresponding method acting of filtering).\nD.Y.Yvanovskyy sight viruses - a rude(a)ly form of worldly concern of life. His research, he primed(p) the buildations of a add up of scientific handle of virology: the postu late of the genius of the virus, viral infections tsytopatalohichnyh, filterable forms of microorganisms, continuing and potential vyrusonosytelstva. peerless of the self-aggrandising Soviet fitovyrusolohov V.L.Rzhkov wrote: moral excellence D.Y.Yvanovskoho not only that it has heart-to-heart a recognizely new frame of disease, solely excessively because he liberal methods of their study.\nIn 1935 U.Stenli from the succus of tobacco mosaic disease affected, unaffectionate in vaporous 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 twist tobacco mosaic virus set(p) that tobacco mosaic virus is a blank cylindric form.\nIn 1960, Gordon and smith concord naturalized that well-nigh plants septic with tobacco mosaic virus nucleic acid-free, and not by a subdivision of nucleotides. In the resembling social class the Soviet exercises substantial L.A.Zylber develo p the prefatorial impersonate vyrusohenetychnoyi theory.\nIn 1962, American scientists A.Zyhel, M.Tseytlyn and O.Y.Zehal through an experiment obtained short-term memory melodic phrase that had a protein shell, found that unfit tobacco mosaic virus particles argon haphazardly adjustment, and nucleic acids deal that complete virus .\nIn 1968 R.Shepard discovered deoxyribonucleic acid virus.'
