Proto-oncogenes are essential for normal development but can become cancer genes when cellular regulators are damaged or modified, e.g. The PowerPoint PPT presentation: "Virology" is … 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. History of Virology Wendell Stanley (1935): crystallization of TMV Delbruck (1940s): modern molecular biology and virology Lwoff (1949): discovery of lysogeny Enders et al., (1949): poliovirus and tissue culture/plaque assays 1980s: Immunology and PCR technology was introduced as well as gene therapy and bioterrorism Parungao-Balolong 2011-2012Friday, June 17, 2011 Year 2001 The complete nucleotide sequence of the human genome is published. Drug resistance quickly appears. Widely used by 1500’s to control smallpox. (Nobel Prize, 1954) This development led to the isolation of many new viruses in tissue culture. Alick Isaacs and Jean Lindemann discovered interferon. 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. However, his head also displays a major wound inflicted either before or shortly after death. Theiler's vaccine was so safe and effective that it is still in use today! Karl Landsteiner (1868-1943) Karl Landsteiner (1868-1943) and Erwin Popper proved that poliomyelitis was caused by a virus. On the primeval Earth, the surface of the planet is just cooling and beginning to harden into a crust. The first viruses also appear. In the event that you were wondering what was the first virus identified, here is a list of early virus discoveries. • Dogs and bats transmit to humans. The Year 1945 • Salvador Luria (1912-1991) and Alfred Hershey (1908-1997) demonstrated that bacteriophagesmutate. This virus is referred to as SARS-CoV-2, and the associated disease as COVID-19. 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. The Year 1939 Emory Ellis (1906-) and Max Delbrück (1906-1981) • Established the concept of the "one step virus growth cycle" essential to the understanding of virus replication. 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 . Smallpox is endemic in China by 1500-1000BC. This was the first rapid, quantitative method of measuring eukaryotic viruses. The first evidence of the existence of viruses came from experiments with filters that had pores small enough to retain … Landsteiner and Popper were the first to prove that viruses could infect humans as well as animals. Leprosy was prevalent in the 14th century Plague in the 15th century Syphilis in the 16th century Small pox in the 17th and 18th century Tuberculosis, measles and scarlet fever in 19th Century Introduction and AIDS in 20th century History of Microbiology Prof. Md.

Work with viruses expands greatly during the 1930s and 1940s with the invention of the ekectron microscope. James, who had never had smallpox , developed a small lesion at the site of vaccination which healed in 2 weeks. A Brief History of Virology. Direct visualization of viruses become possible after the electron microscope is introduced. 100 Million Years Ago.The Cretaceous Period. Birth of virology Adolph Mayer-1883. Rous is the first person to show that a virus could cause cancer in animals (see also 1981). (Nobel Prize, 1965). Year 1983 Luc Montaigner and Robert Gallo announced the discovery of human immunodeficiency virus (HIV), the causative agent of AIDS. HIV: No vaccine; drugs are somewhat effective but are costly and toxic. To Catch a Virus is a historical account of the development of diagnostic virology intertwined with accounts of disease outbreaks that spurred advances in technology. Iwanowski was the first person to discriminate … In 1879, Adolf Mayer (Director of the Agricultural Experiment Station at Wageningen, The Netherlands) was the first to study this disease of tobacco. by virus transduction. Other course resources. Now viruses could be counted!

The Year 1950 André Lwoff (1902-1994) Louis Siminovitch and Niels Kjeldgaard discovered lysogenic bacteriophages in Bacillus megaterium irradiated with ultra-violet light and coined the term prophage. what are viruses?. SARS: Vaccines are being developed; easy transmission to humans but outbreaks controllable quarantining patents in hospitals coupled with stringent monitoring of all potential contacts. "Principles of Molecular Virology, Third Edition" provides an essential introduction to modern virology in a clear and concise manner. ~Michael Crichton, Timeline. • Through experimental transmission to mice, in 1900 Walter Reed demonstrated that yellow fever was caused by a virus, spread by mosquitoes. 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 mummy shows that his left leg was withered and his foot was rigidly extended like a horse's hoof - classic paralytic poliomyelitis.

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. Although diseases caused by viruses have been known since the 1700s and cures for many were (somewhat later) effected, the causative agent was not closely examined until 1892, when a Russian bacteriologist, D. Ivanovski, (Nobel Prize, 1969) • This work proves that similar genetic mechanisms operate in viruses as in cellular organisms and lays the basis for the understanding of antigenic variation in viruses.

Cellular origins - perhaps they are sub-cellular, functional assemblies of macromolecules which have escaped their origins inside primitive cells. Although the initial evidence for DNA as the molecular basis of genetic inheritance was discovered using a bacteriophage, this principle of course applies to all cellular organisms (though not all viruses!). The recommended textbook is Principles of Virology. The supercontinent Pangaea has begun to break up, but the continents have still not drifted into their present positions. He is known as the “Father of Virology”. Francis Peyton Rous (1879-1970) • Francis Peyton Rous (1879-1970) demonstrated that a virus (Rous sarcoma virus) can cause cancer in chickens. Smallpox is endemic in China by 1500-1000BC. The Year 1143 BC Ramesses V's preserved mummy shows that he died of smallpox at about the age of 35 in 1143 BC.

(Nobel Prize, 1976) Blumberg went on to develop the first vaccine against the HBV, considered by some to be the first vaccine against cancer because of the strong association of hepatitis B with liver cancer. 6. Most plant disease models use different climatic variables and operate at a different spatial and temporal scale than do the global climate models. • Rabies virus causes disease and death in most mammals. The Birth of Virology Martinus Beijerinck-1897 Found that the agent could reproduce only in the host and was not inactivated by alcohol. 1950s.

Felix d'Herelle (1873-1949) • Following Frederick Twort'swork, Felix d'Herelle independently recognizes viruses which infect bacteria, which he calls bacteriophages(eaters of bacteria). The Year 1193 BC The Pharaoh Siptah rules Egypt from 1200-1193 BC when he dies suddenly at the age of about 20. Influenza: Effective strain-specific vaccines are generated each year, but new variant and potentially dangerous strains emerge each year. • His mummified body lays undisturbed in his tomb in the Valley of the Kings until 1905 when the tomb was excavated. 1. introduction. This was acheived in 8 years. Tulips were traded with a rage in the 1630’s and speculation began and large fortunes were made. Salvador Luria (1912-1991) Alfred Hershey (1908-1997). Rabies is known on all continents. The climate is much hotter and drier than today. Thucydides wrote of individuals who recovered from the plague, which was raging in Athens at the time. Thought that the pathogen might be a small bacterium. In response, the practice of variolation is developed. In general, infections were blamed on sins and punishment, balances of “vital humors” or on “miasma,” (rotten smells).
