38
Q

Q: Compare Infectious v. Noninfectious diseases.

A

A:
- Infectious Diseases: Diseases that can be spread from person to person (animal to person)
- Non-infectious Diseases: Diseases that cannot be spread from person to person. They are based on genetic predisposition & lifestyle factors.
–> Ex: Cancer, Asthma, Arthritis, Diabetes

A:
- Direct Contact: Direct body contact
- Droplet Transmission: Short-range coughing or sneezing

40
Q

Q: Describe some examples of Indirect Contact Transmission.

A

A:
- Airborne: Pathogens in the air carried by dust or droplets.
- Vehicles: Food, water, biological products, fomites
- Vectors: Mosquitoes, fleas, ticks, can carry pathogens passively or the pathogens multiplies in vector

41
Q

Q: What are light microscopes?

A

A: Light microscopes use light for visualization. These microscopes can magnify up to 1,000x.

42
Q

Q: What are brightfield microscopes?

A

A: Microscopes where the background is illuminated. Used to see microbes that have been stained.

43
Q

What microscope would best be used to see microbes that have been stained?

A

Brightfield microscopes

44
Q

Q: What are darkfield microscopes?

A

A: Microscopes where the background is dark. Used to see live, unstained specimens.

45
Q

What microscope would best be used to see live, unstained microbes?

A

darkfield microscope

46
Q

Q: What are phase-contrast microscopes?

A

A: Microscopes that use contrast without staining the specimen.

47
Q

What microscope would use contrast to see a microbe without staining them?

A

Phase-contrast microscope

48
Q

Q: What are fluorescence microscopes?

A

A: Microscope used to see stain that contain particles that will appear fluorescent.

49
Q

What microscope would be used if the specimen was stained with a fluorescent stain?

A

Fluorescence microscope

50
Q

Q: What are confocal scanning laser microscopes?

A

A: Microscope that uses fluorescence to view a single plane. Each image is an optical slide through a specimen.

51
Q

Q: What are differential interference contrast microscopes?

A

A: Very contrasted to give an image a 3D & shadowed appearance.

52
Q

Q: What are electron microscopes?

A

A: Electron microscopes use electrons for visualization instead of lights. These microscopes can be used to magnify 10,000x - 100,000x

53
Q

Q: What are transmission electron microscopes?

A

A: Microscopes where electrons pass through the specimen.

54
Q

Q: What are scanning electron microscopes?

A

A: Microscopes where electron bounce off specimen to create a surface image.

55
