FGCU Microbiology (Exam 1)
Inspection and Identification - ✔️✔️Microbes can be identified through:
- microscopic appearance
- characterization of cellular metabolism
- determination of products given off during growth, presence of enzymes, and
mechanisms for deriving energy
- genetic and immunological characteristics
How does understanding microorganisms help us? - ✔️✔️helps use prevent food
spoilage, prevents disease occurrences, and we can better understand how aseptic
techniques can be used to prevent contamination and infection
Define microorganisms - ✔️✔️organisms that are too small to be be seen with the
unaided eye
Define pathogen - ✔️✔️microbes that cause disease
How do microorganisms benefit humans? - ✔️✔️they decompose organic waste,
produce fermented food, industrial chemicals, and they produce products used in
manufacturing and treatment
How do microorganisms harm humans? - ✔️✔️a few microorganisms are pathogenic
and can cause disease

disease (evidence for germ theory)
Postulate 1 - ✔️✔️the same microorganism has to be present in every case of disease
Postulate 2 - ✔️✔️The microorganisms are isolated from the tissues of a dead animal,
and a pure culture is prepared
, Postulate 3 - ✔️✔️Microorganisms from the pure culture are inoculated into a healthy,
susceptible animal. The disease is reproduced
Postulate 4 - ✔️✔️The identical microorganisms are isolated and found in the tissue
specimens of the experimental animal

living matter, or a "vital force"
How did Jenner demonstrate concept of vaccination? - ✔️✔️He developed vaccination
for smallpox by inoculating individuals with cowpox (creating immunity for smallpox)
Innoculation - ✔️✔️the implantation of microorganisms into or onto culture media
Incubation - ✔️✔️medium is placed into a temperature controlled chamber to
encourage multiplication
Isolation - ✔️✔️an individual cell is separated from other cells on a nutrient surface and
forms a colony
Complex media - ✔️✔️contains at least one ingredient that is not chemically definable
(extracts of animals, plants, or yeasts)
Chemically defined media - ✔️✔️media whose compositions are precisely chemically
defined (you know exactly what's in the media)
