Microbiology |
Study of organisms to small to be seen with unaided eye. |
|
|
|
Organisms |
Called microbes= microorganisms |
|
|
|
Several disciplines within field of Microbiology |
1.Virology 2.Phycology 3.Mycology 4.Bacteriology 5.Parasitology |
|
|
|
1. Virology |
Study of viruses |
- viruses are acellular pathogens that cause disease. Ex.) Polio Virus- gets into nervous system, muscles paralyzed + wasting away |
|
|
2. Phycology |
Study of algae |
Algae=simple synthetic organisms that are aquatic. Algae can cause disease: Redtide, karenia brevis |
|
|
3. Mycology |
Study of fungi |
Not all are microscopic. Pathogen fungus- causes atheletes foot |
|
|
4. Bacteriology |
Study of bacteria |
Bacteria= single cell prokaryotic organisms. /\ lack nucleus. DNA loose in cytoplasm |
|
|
Pyogenic |
Cause production of pus |
|
|
|
MRSA |
Methicillin resistant staph aureus |
|
|
|
5. Parasitology |
Study of parasites |
|
|
|
Parasite |
Species of organism that lives at the expense of another species(host). Parasite gets nutrients + energy from host. |
Ex.) Parasite- tapeworms |
|
|
Ecology |
Study of relationship of an organism to its environment |
|
|
|
Environment |
Everything outside the organisms - include |
|
|
|
Symbiosis |
Study of two different species cohabiting (coexisting) |
|
|
|
3 Common kinds of Symbiosis |
1. Parasitism 2. Commensalism 3. Mutualism |
|
|
|
1. Parasitism |
Type of of sybiosis where one species is benefited(parasite) and the species is harmed(host) |
Ex) Tapeworm in human host |
|
|
2. Commensalism |
Type of sybiosis where one species benefits(commensal) +other species is neither harmed nor helped.(host) |
Ex) eyelash mites in base of eyelashes |
|
|
3. Mutualism |
Type of symbiosis in which both species benefit |
Ex) Escherichia Coli • feeds on food we can not digest • releases vitamin B, K • in human intestines we absorb vitamins B, K (for clotting) E, coli also fights off new pathogen |
