The history of virology can be divided into a number of eras: these span (1) the discovery of viruses as entities distinct from other disease-causing pathogens, (2) the association of many major human diseases with causative viruses, (3) the development of methods for virus isolation and characterization, (4) the defining of the chemical properties of viruses, and (5) the design and … Max Theiler (1899-1972) Max Theiler was the first to propagate yellow fever virus in chick embryos and successfully produced an attenuated vaccine - the 17D strain. Influenza: Effective strain-specific vaccines are generated each year, but new variant and potentially dangerous strains emerge each year. Iwanowski was the first person to discriminate … (Nobel Prize, 1975). • Unfortunately, neither Iwanowski nor the scientific community fully realize the significance of these results. Proof that Animal Diseases can be Caused by Viruses F.A.J. The Year 3700 BC • The first written record of a virus infection consists of a heiroglyph from ancient Egypt, drawn in approximately 3700 BC, • Which depicts a temple priest called Ruma showing typical clinical signs of paralytic poliomyelitis. Although the initial hopes for interferons as broad spectrum antiviral agents equivalent to antibiotics have faded, interferons were the first cytokines to be studied in detail. The supercontinent Pangaea has begun to break up, but the continents have still not drifted into their present positions. The Year 1892 • On 12th February, Dmitri Iwanowski, a Russian botanist, presents a paper to the St. Petersburg Academy of Science which shows that extracts from diseased tobacco plants can transmit disease to other plants after passage through ceramic filters fine enough to retain the smallest known bacteria. ~Michael Crichton, Timeline Viro100: Virology 3 Credit hours NUST Centre of Virology & Immunology, On the primeval Earth, the surface of the planet is just cooling and beginning to harden into a crust • Rain forms pools containing many organic molecules and the first simple life forms appear.

Notable Persons and their Contribution to the Science of Virology. Proto-oncogenes are essential for normal development but can become cancer genes when cellular regulators are damaged or modified, e.g. Proteins associate into structural units (this is what we see in the electron microscope or when we start to disassociate a capsid), the structural units are known as capsomers . (Nobel Prize, 1975) Alfred Hershey (1908-1997) and Martha Chase demonstrated that DNA was the genetic material of a bacteriophage. Dinosaurs roam the earth. He is credited as the first person to transmit tobacco mosaic virus by using the extracts from the diseased […] In response, the practice of variolation is developed. The term virus is derived from a Latin word vios meaning venum or poisnous fluid. It is a highly enjoyable and readable text with numerous illustrations that enhance the reader's understanding of important principles. techniques. (Nobel Prize, 1975). 4. virology. In response, the practice of variolation is developed. Abstract. • Stanley's work is the first step towards describing the molecular structure of any virus and helps to further illuminate the nature of viruses. Year 1976 J. Michael Bishop and Harold Varmus discover that the oncogene from Rous sarcoma virus is also found in the cells of normal animals, including humans (Nobel Prize, 1989). HISTORY OF VIROLOGY. (Nobel Prize, 1954) This development led to the isolation of many new viruses in tissue culture. The peach-potato aphid (Myzus persicae), one of UK’s most damaging aphids, has been found to be flying two weeks earlier for every 1°C rise in the average temperature.

The Year 1886 John Buist (a Scottish pathologist) stained lymph from skin lesions of a smallpox patient and saw "elementary bodies" which he thought were the spores of micrococci. • This was the first rapid, quantitative method of measuring eukaryotic viruses. The discovery of reverse transcription established a pathway for genetic information flow from RNA to DNA, refuting the so-call "central dogma" of molecular biology. The Year 1963 Baruch Blumberg discovers hepatitis B virus (HBV). Year 1973 Peter Doherty and Rolf Zinkernagl demonstrate the basis of antigenic recognition by the cellular immune system.

Tulipomania in the Late 16th Century Tulips with flower breaking symptoms were prized in Europe and traded for very large sums of money. ~Michael Crichton, Timeline. virology. disease or symptom?. • Regressive evolution maybe these early viruses are degenerate life forms which have lost many functions that other organisms possess and have only retained the genetic information essential to their parasitic way of life. Unfortunately, neither Iwanowski nor the scientific community fully realize the significance of these results. About 11% of the human genome is composed of retrovirus-like retrotransposons: "transposable elements in which transposition involves a process of reverse transcription with an RNA intermediate similar to that of a retrovirus". Walter Reed (1900) showed that yellow fever in humans was caused by a filterable virus that was transmitted by mosquitoes Ellerman and Bang (1908) demonstrated that leukemia in chickens was caused by a virus.

Although the concept of lysogeny had been around since the 1920s, this work clarified the existence of temperate and virulent bacteriophages and led to subsequent studies concerning the control of gene expression in prokaryotes, resulting ultimately in the operon hypothesis of Jacob and Monod. History of Virology: Viruses are very small and ultra-microscopic structures responsible for causing serious diseases both in plants and animals including man. The concept behind modern virology can be traced back to Adolf Mayer, Dimitri Ivanofsky and Martinus Beijerinck who, independently in the late 1880’s, discovered what was later to be called tobacco mosaic virus (TMV). virus; virus replication; virus particles; 1143 bc; … Wendell Stanley (1887-1955) Wendell Stanley (1887-1955) crystallizeed tobacco mosaic virus (TMV) and showed that it remains infectious (Nobel Prize, 1946). Introduction Parasitology. This work laid the basis for the understanding of virus replication - that virus particles do not "grow" but are instead assembled from preformed components. Tulips were traded with a rage in the 1630’s and speculation began and large fortunes were made. The phage group stimulated studies of bacteriophages and helped establish the field of molecular biology ; Study of tumor viruses led to discoveries in molecular biology and understanding of the nature of cancer ; 10 A Brief History of Virology 11 A Brief History of Virology 12 Detection and Measurement of Viruses It is not clear where they have come from: • Independent entities • Cellular origins • Regressive evolution. This virus is referred to as SARS-CoV-2, and the associated disease as COVID-19. A Concise History of Immunology Steven Greenberg The role of smallpox in the development of vaccination The concept of immunity from disease dates back at least to Greece in the 5th century BC. Viro100: Virology 3 Credit hours NUST Centre of Virology & Immunology. Year 1983 Luc Montaigner and Robert Gallo announced the discovery of human immunodeficiency virus (HIV), the causative agent of AIDS. (Nobel Prize, 1954) This development led to the isolation of many new viruses in tissue culture. But liver cancer deaths caused by viral infection will continue for many decades. 1882-1886: Actual era of Plant Virology started with scientific investigation by Adolf Mayer 1886- Adolf Mayer – infectious sap from tobacco induce disease; gave term Mosaikkrankheit for mosaic 1892 Ivanowski – Sap retained infectivity even after filtration through chamberland porcelain filter, The Year 1949 Thomas Weller (1915–) Frederick Robbins (1916–) John Enders (1897-1985) John Enders, Thomas Weller (1915–) and Frederick Robbins (1916–) were able to grow poliovirus in vitro using human tissue culture. History of Virology. VIROLOGY - . • The first viruses also appear. Recognizing that survivors of smallpox outbreaks are protected from subsequent infection, variolation involves inhalation of the dried crusts from smallpox lesions like snuff, or in later modifications, inoculation of the pus from a lesion into a scratch on the forearm The Year 1500-1000 BC. Showed that the agent was soluble and could not be grown in culture. More research is needed to obtain base-line information on different disease systems. 3. virus replication. rna phage gene expression and replication ms2 & q b : rna bacteriophages provide examples, Veterinary Bacteriology and Virology 101 - .
