Microbiology Ch 1-2

Unit 1

Koch's Postulates Prove that a specific microbe is the cause of a specific infectious disease.
Zooplankton Microscopic marine animals; components ok planlton
Pathogens Cause all infectious disease
Bioremediation using microorganisms to clean up the enviroment
Zoonoses infectious disease transmitted from animals to humans
opportunistic pathogens do not usually cause infectious disease but can under cirtain circumstances
indigenous microflora microorganisms that live in and on us
saphrophytes organisms that live on dead or decaying organic matter
Robert Koch Developed an experimental procedure that could be used to prove that a specific organism is the cause of a specific infectious disease
Proposed the theory of biogenesis Rudolf Virchow
Discovered the causitive agent of the plague Alexandre Emil Jean Yersin
The first person to observe live bacteria and protozoa Anton van Leeuwenhoek (he also invented the simple microscope which magnifyed up to 300x)
Resolving power of the unaided eye 0.2mm
Total magnification achieve when oil immerson lens is used X1000
Resolving power of the compound microscope compared to the unaided eye 1000x
Compound light microscope Wavelength of visible light limits the size of objects that can be seen
fluorescence microscopy used in immunology labs
# of micrometers in a milimeter 1000
resolving power of the transmission electron micrscope 0.2nm nanometers
# of nanometers (nm) in a micrometer 1000
Germ theory of disease Pastuer proposed it Koch developed it.Germs are the major cause of many diseases to the development of antibodies
Process of pasteurization steam, pressure, or chemicals are used to REDUCE the # of pathogens
Genetic engineering insertion of foreign genes into microorganisms to produce specific gene products or to enable them to be used for other purposes
