History of Micro L1 Flashcards
reported life’s smallest units were cells, beginning of cell theory
Robert Hook
lens maker, discovered microbial world, call them “beasties,” protozoa in 1674, bacteria in 1676
Leeuwenhoek
dev. taxonomic system for naming plants/ animals, grouped them together
Carolus Linnaeus
showed decaying meat isolated from flies did not get maggots
Francesco Redi
boiled and sealed gravy infusions, observed they were cloudy days later, attributed to spontaneous life force
John T. Needham
boiled infusions almost one hour, closed vials stayed clear, those exposed to air - cloudy
Lazzaro Spallanzi
discovered anaerobes ferment grape juice, pasteurization, and began industrial microbio or biotec, using microbes to manufacture products
Louise Pasteur
challenged case of spontaneous generation with concept of biogenesis - the idea that living cells only arise from pre-existing cells
Rudolf Virchow
showed fermentation does not need living cells, demonstrated presence of enzymes, began field of biochem
Edward Buchner
investigated etiology, studied infected animal blood and showed given pathogen causes specific disease
Robert Koch
showed protozoan cause of malaria
Charles Laveran
described bacteria causing diphtheria
Edwin Klebs
disease in tobacco plant passed through filter, a virus
Ivanowski and Beijerinck
proved in 1900 viruses cause disease
Walter Reed
developed stain using series of dyes to separate bacteria into 2 groups
Christian Gram
Hungary, required hand washing with chlorinated lime water to eliminate “cadaver particles” carrying disease
Ignaz Semmelweis
founder of antiseptic surgery, used phenol (carbolic acid)
Joseph Lister
nurse introduced cleanliness/antiseptic technique into nursing
Florence Nightingale
studied cholera in contaminated water, documented need for clean water/sewage treatment, foundation for infectious control and epidemiology
John Snow
study of immunology and vaccination, used cowpox pus to inoculate son, son got cowpox but became immune
Edward Jenner
studied chem that killed microbes deferentially but not people, chemotherapy
Paul Ehrlich
proposed bacterial biochem shared by all living things
Kluyver and Van Niel
determined genes determine molecules of DNA
Avery/Macleod/Maclyn
proposed gene sequence could provide understanding of evolutionary relationships
Linus Pauling
established genes actively related to function of protein encoded by that gene
Beadle/Tatum
significant influence in nucleic acids reveal 3 major groups: bacteria, archae and eukaryotes
Carl Woese
middle east respiratory syndrome, 339 cases between 4/2012 and 6/2014
MERS
sever acute respiratory syndrome, in China in 2002, coronavirus
SARS
H5N1 or bird flu, 2003 killed millions of poultry and 24 people, 2013 different avian flu H7N9, 131 people sick in China
avian influenza
methicillin resistant S. aureus
1980s MRSA
vancomycin intermediate S. aureus
1990s VRSA
multidrug resistant TB, resistant to at least isoniazid and rifampicin
MDR-TB
