Microbiology 201 - Ivy Tech - Chapter 1
Vocab
Algae - ANS-unicellular and multicellular PHOTOSYNTHETIC eukaryotes, large algae:
kelp & seaweed, unicellular algae: common in fresh water and oceans, provide most of
the world's oxygen
Antispetic technique - ANS-practice of sanitization etc. to reduce the transfer of
pathogens
Bacteria - ANS-prokaryotes with cell wallls made of petidoglycan
Chemotherapy - ANS-targeting specific bacteria with chemicals that are nontoxic to
humans
Control Groups - ANS-group in an experiment where the independent variable is not
introduced used as a benchmark to measure experimental group's results
Experimental Group - ANS-group in experiment where the independent variable being
tested is introduced
Fungi - ANS-eukaryotes, obtain food from outside source, unlike plants, have cell walls,
ex. yeast and mold
Germ Theory of Disease - ANS-idea that microorganisms are responsible for disease
spurred by Pasteur's discovery that bacteria spoil wine
Immunology - ANS-practice of immunizing patients with form of virus/bacteria
Koch's Postulates - ANS-1. Suspected causative agent must be found in every case of
the disease AND be absent from healthy hosts.
2. The agent must be isolated and grown outside the host.
3. When the agent is introduced to a healthy, susceptible host, the host must get the
disease.
4. The same agent must be found in the diseased experimental host.
Microorganisms - ANS-Organisms too small to be seen without a microscope
