Unit 1
| Question | Answer |
|---|---|
| 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 |
