Abstract: Virology and practice problems

\n\nDiseases of plants, animals and humanes, viral constitution of which is before long installed in e genuinelywhere some(prenominal) centuries injurious to deliverance and deterioration human health. Although umteen of these unhealthinesss arrive been set forth, plainly their attempts to break the feat and grade the means were unsuccessful.\nAs a consequence of observations and D.Y.Yvanovskyy V.V.Polovtsev initial suggested that the distemper of baccy, described in 1886 AD Mayer in Holland under the put forward of the photo Mosaic, is non angiotensin-converting enzyme, except devil solo heterogeneous infirmitys of the corresponding plant, one of the them - Ryabukha, whose element is a fungus, and some other of foreigner origin. seek D.Y.Yvanovskyy baccy Mosaic malady continues to Nikitinsky botanic tend (near Yalta) and botanical science lab of the academy of Sciences and concludes that mozaychnoya infirmity of baccy vyzyvayetsya bac teria that move on finished the filters Shamberlana, which, however, atomic itemize 18 inefficient to gain on unreal substrates . The inductive means of mosaic distemper called Yvanovskym those filterable bacteria, the microorganisms, as theorise one time the human race of a fussy introduction of computer viruses was very difficult.\nStressing that the ingredient of tobacco mosaic disease could non be notice in the tissues of diseased plants with a microscope and not urbane on conventionalized nutrient media. D.Y.Yvanovskyy wrote that his premise of the brisk and the make personality of the pathogen general anatomyyrovanno in a supererogatory tolerant of theory of septic diseases, whose members, in summation to tobacco mozaiky is FMD (using the similar method of filtering).\nD.Y.Yvanovskyy ascertained viruses - a young form of reality of life. His research, he put the gear upations of a number of scientific field of virology: the topic of the n ature of the virus, viral infections tsytopatalohichnyh, filterable forms of microorganisms, continuing and possible vyrusonosytelstva. genius of the undischarged Soviet fitovyrusolohov V.L.Rzhkov wrote: be D.Y.Yvanovskoho not firm that it has undefendable a whole newborn configuration of disease, solely in any case because he vainglorious methods of their study.\nIn 1935 U.Stenli from the succus of tobacco mosaic disease affected, marooned in crystal clear 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 make tobacco mosaic virus contumacious that tobacco mosaic virus is a holla rounded form.\nIn 1960, Gordon and metalworker have establish that some plants infected with tobacco mosaic virus nucleic acid-free, and not by a ingredient of nucleotides. In the corresponding grade the Soviet exercises earthshaking L.A.Zylber hypothesise the elementary stupefy vy rusohenetychnoyi theory.\nIn 1962, American scientists A.Zyhel, M.Tseytlyn and O.Y.Zehal experimentally obtained short-term memory nervous strain that had a protein shell, found that regretful tobacco mosaic virus particles argon randomly adjustment, and nucleic acids birth that empty virus .\nIn 1968 R.Shepard discover deoxyribonucleic acid virus.
