(Dear, King, Phillip, Came, Over, For, Good, Soup)
5 things all cells have
cell membrane, DNA, ribosomes, cytoplasm, cell wall
Virus
Acellular, parasitic particles, composed of a nucleic acid and proteins
Prokaryote
Microscopic, unicellular organism, lack nuclei and membrane-bound organelles. Includes bacteria and archaea
Eukaryote
Unicellular and multicellular, has a nucleus and membrane-bound organelles. Includes major cell types, animal cells, plant cells, fungi, protozoa and protists.
Parasite
Live on or in the body of another organism called the host and it damages the host.
Pathogens
Microorganisms that can cause disease or infections.
Medical micro, public health micro, epidemiology
How microbes effect humans and monitor and control disease spread.
Biotechnology
Microbes used for products; natural ability
Genetic engineering
Microbes used for products; altered or enhanced ability
Industrial micro
Microbes used for products; large qualities
Immunology
Protective substances, reactions caused by microbes, blood testing, vaccines, allergy testing
Ag micro
Connection between microbes and domesticated plants and animals, impacts on food supply, and human disease due to interaction
Food micro
Study the impact of microbes on food supply, ensure adequate food supply
Leeuwenhoek
Made first microscope, saw animal like molecules which turned out to be microbes. Used his own teeth plaque
Jenner
Developed the first vaccine (smallpox). Noticed that milkmaids got cowpox which is a mild form of smallpox. He gave a boy cowpox then inoculated him to smallpox and had an immune response. Didn’t understand the mechanism. Replicated study. Write a paper with the term vaccination.
Holmes
Observed women who give birth at home had fewer infections than those in the hospital
Semmelweis
Correlated infections with physicians coming directly from the autopsy room to the maternity ward. childbed fever.
Lister
Introduced aseptic or sterile techniques to reduce microbes in medical settings and prevent wound infection. Chemicals used on hands to disinfect before surgeries, used heat for sterilization, disproved miasma
Tyndall and Cohn
Demonstrated the presence of heat resistant forms of some microbes, Cohn determined these forms to be heat-resistant bacterial endospores
Pasteur (and Koch)
Germ Theory of Disease. Microbial diseases are not caused by sin, bad character, or poverty. Microbes causing fermentation and spoilage. Disproved spontaneous generation or microorganisms, developed pasteurization, demonstrate what is now germ theory of disease. Father of Micro. Developed rabies and anthrax vaccines
Von Linné
Created taxonomy, the organizing, classification, and naming of living things
Taxonomy
The organizing, classifying, and naming living things and the formal system originated by Von Linne
