人类与传染病的斗争(2) Battles to Infectious Diseases (2)

3 Vocabulary of Infectious disease
疾病,病:disease, illness, disorder 疾病预防:Disease prevention 疫:Epidemic, communicable disease, (瘟疫 plague) 防疫:Epidemic prevention 免疫:Immunity 免疫学:Immunology 疫苗:Vaccine 免疫接种 Vaccination (Inoculation)

4 How did we win the battles
Identify the pathogens - Germ Theory 病原理论 Effective therapy – Vaccine and Antibiotics 疫苗和抗菌素 Prevention and control - Public Health System 公共卫生

5 Establishment of Germ Theory
De Contagione et Contagiosis Morbis (On infection and infectious diseases,1546) He proposed that epidemic diseases are caused by transferable tiny particles or "spores" that could transmit infection by direct or indirect contact or even without contact over long  distances. Girolamo Fracastoro (Italian) 《西佛里斯──法国疾病(Syphilis sive de morbo Gallico)》1521

6 Antonie van Leeuwenhoek 1632-1723
Establishment of Germ Theory A Dutch cloth merchant used new method for grinding and polishing tiny lenses of great curvature which gave magnifications up to 270 diameters First to see and describe bacteria as animalcules 小动物, Leeuwenhoek became the pioneer of microbiology Antonie van Leeuwenhoek

7 Establishment of Germ Theory
Created germ theory of disease, (germ theory vs miasma theory and spontaneous generation) Created the first vaccine for rabies  Invented Pasteurizaion He is regarded as one of the three main founders of microbiology, together with Ferdinand Cohn and Robert Koch. 巴斯德 Louis Pasteur

8 Germ Theory vs Spontaneous Generation Theory
"Do not put forward anything that you cannot prove by experimentation" broth broth swan-neck flask experiment

9 Establishment of Germ Theory
The Nobel Prize in Physiology or Medicine 1905 "for his investigations and discoveries in relation to tuberculosis"  He discovered Mycobacterium tuberculosis in March 24,that day is designated as World Tuberculosis Day“世界结核病日” 科赫 Robert Koch 1843-1910

10 Establishment of Germ Theory
Heinrich Hermann Robert Koch ( ) German physician Isolating  Bacillus anthracis (1877), Mycobacterium tuberculosis   (1882) and Vibrio cholera (1883) Invented pure culture of bacteria Development of Koch’s postulates

15 The Nobel Prize in Physiology or Medicine 2005
Barry Marshall and Robin Warren from Australia won 2005 Nobel Prize in Physiology or Medicine: "for their discovery of the bacterium Helicobacter pylori and its role in gastritis and peptic ulcer disease"  Barry J. Marshall J. Robin Warren b b. 1937

16 1982,Marshall and Warren discovered Helicobacter pylori (Hp) and approved its relationship with gastritis, peptic ulcer and duodenal ulcer , The bacteria secrete urease, that hydrolyse urea to produce ammonia (C13 breath test) CO(NH2)2 + H2O = CO2↑ + 2NH3↑

17 March Barry Marshall was awarded as Honorary Professor of Zhejiang University, and delivered a speech: An usual disease and unusual discovery.

18 Discovery of Plasmodium malariae

23 Who defeated Napoleon? Endemic Typhus
Fatal epidemics of typhus outbroke among French soldiers, resulting severe depletion of troopers, when Napoleon entered Moscow only 90,000 men left. 斑疹伤寒 Typhus (Trench Fever or Jail Fever) Caused by Rickettsia transmitted by louse or flea. Rickettsia Prowazekii

24 Discovery of pathogen of typhus
The Nobel Prize in Physiology or Medicine 1928 was awarded to Danish scientist Charles Nicolle “for his work on typhus“, he discovered the disease is transmitted by biting of flea or louse. (Pasteur Institute) Charles Nicolle -1936

25 Discovery of pathogen of typhus
Two scientists Howard Ricketts and Howard Ricketts were credited for discovery of pathogen of typhus and both died from the disease infected in the laboratory. The pathogen of typhus was named after them (Rickettsia prowazekii). Stanislav Von Prowazek Czech zoologist and parasitologist (1875–1912) Howard Ricketts American pathologist ( )

27 Discovery of Viruses Ивановсқий (1864-1920),
The very first virus discovered is credited to the St. Petersburg Academy of Science on the 12th February 1892 by Dmitri Iwanowsky a Russian botanist. While studying mosiac tobacco disease, he found that the agent causing the disease was small enough for pass though ceramic filter that are small enough to trap all bacteria. This is generally accepted as the beginning of Virology. Ивановсқий ( ),

28 Martinus Beijernick (1851-1931)
Discovery of Viruses 1898, Dutch scientist Martinus Beijernick confirmed Iwanowski's results on tobacco mosaic virus. He developed with the term "contagium vivum fluidum" which means “soluble living germ” as first the idea of the virus.  Martinus Beijernick ( )

Blumberg ( ) D. Carleton Gajdusek ( )

40 Kuru Disease Prevalent in Native Fore people from Fore Islands of New Guinea in 1950s. Among local inhabitants 80% had the disease particularly in women and children. Symptoms: tremble, ataxia, dementia, disability of moving, died in 3-6 months. After long-term survey Gajdusek discovered that the endemic was associated with eating the brain of the dead in funeral. This practice was banned and the disease no longer occurred.

41 Discovery of Prions The Nobel Prize in Physiology or Medicine 1997
"for his discovery of Prions - a new biological principle of infection“ Prusiner proposed that the cause of transmissible spongiform encephalopathy (TSE)was a type of infectious protein (Prions) Stanley B. Prusiner University of California School of Medicine b. 1942

56 Jonas Salk invented live polio vaccine in 1954
Three American scientist John Enders, Thomas Weller and Frederick Robbins discovered method to culture polio virus using non-nervous tissue, they won Nobel Prize in 1954 Jonas Salk invented live polio vaccine in 1954 Franklin Roosevelt himself was a victim of polio, launched the March of Dimes to raise the National fund for polio prevention in 1938 Albert Sabin invented oral live-attenuated vaccine (pills)

57 Chemotherapy for Syphilis 梅毒
Before chemotherapy introduced, mercury used be the only cure for syphilis, but the harm of mercury poisoning is more serious than the disease itself A night in the arms of Venus leads to a lifetime on Mercury 风流一夜情 水银伴终生 Treponema pallidum

58 Chemotherapy for Syphilis
Paul Ehrlich intended to find the magic bullet against microorganism from chemical dyes In 1909 he and his student  Hata Sahachiro (秦佐八郎) developed a arsenical compounds Salvarsan (Arsphenamine ,606), which was effective against syphilis Ehrlich received the Nobel Prize in Medicine together with Mechnikov in 1908 Paul Ehrlich(1854-1915) and Hata Sahachiro Hata 秦佐

59 Discovery of antibiotics and the therapeutic revolution
Domagk found f red dye Prontosil and its derivant sulfonamide to be effective against streptococcus, and treated his own daughter Alice with it, saving her the amputation of an arm. Prontosil became the first commercially available antibacterial agent Gerhard Domagk

60 Discovery of antibiotics and the therapeutic revolution
Afterward a series of sulfonamides 磺胺 were synthesized and sulfonamides became a revolutionary weapon at the time, but were later replaced by penicillin Domagk received the 1939 Nobel Prize in Physiology or Medicine Benzene ring

65 Discovery of antibiotics and the therapeutic revolution
After the discovery of penicillin and streptomycin, more antibiotics were isolated from the soil, upon 1960s more than 600 antibiotics were available in practice Thanks of discovery and application of antibiotics severe bacterial infection has no longer a incurable disease and the average life expectancy increased by 10 year leading to the therapeutic revolution.

66 Public Health System 公共卫生系统
Early religions attempted to regulate behavior that specifically related to health, from types of food eaten, to regulating certain indulgent behaviors, such as drinking alcohol or sexual relations.  Rome:water supply and sewage system, public bath and public toilet After plague outbreak in Middle Ages: clearance, sanitation, removing bodies of the dead, burning parts of the city and quarantine system 1848 passed British Public Health Act 1946 CDC was founded in US (Communicable Disease Center-1980 Centers of Disease Control)

67 Adult HIV Prevalence

68 August 1854 cholera outbreak in London Soho, 140,000 infected and 618 died. John Snow ( )surveyed the cause and transmission of the disease Broad street Brewer house midway house

69 Public Health System Public health is “the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals.” (1920, C. E.A. Winslow) The goal of public health is to improve lives through the prevention and treatment of disease. The WHO defines health as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity."

70 Functions of Public Health
Prevention of infectious diseases and other diseases through primary, secondary, tertiary prevention Changing health behavior, improving diet and nutrition through health education and health promotion as well as law and regulation Improving environment including living environment and occupational environment Reproduction health Epidemilogical survey, disease surveillance, statistics, research and education
