Question 1

Classification according to Function/Use:

5

Answer 1

1. general purpose media
2. enriched culture media
3. enrichment broth
4. transport culture media
5. selective & differential culture media

Question 2

• contains BASIC NUTRITIONAL requirements for NON-FASTIDIOUS microorganims.
• used as BASE MEDIUM in the preparation of other culture media.

Answer 2

GENERAL PURPOSE.

Question 3

examples of PRIMARY MEDIA:

Answer 3

1. nutrient agar (NA)
2. nutrient broth (NB)
3. tryptic soy broth (TSB)
4. tryptic soy agar (TSA)

Question 4

same definition as BASIC MEDIA +
- they also contain additives, enriching substances, or supplements to support the growth of fastidious organisms

Answer 4

enriched culture media

• blood agar plates (BAP)
• chocolate agar plates (CAP)

Question 5

• primary media used to support or favor the selective growth of pathogens in a specimen, such as stool or sputum.
• number of pathogens > number of normal flora

Answer 5

enrichment broth

Question 6

primary isolation CM which maintains the viability of bacteria w/o allowing RAPID MULTIPLICATION if there is an anticipated delay in bringing the specimen collected

viability- ability to live

Answer 6

transport culture media

Question 7

Favors the growth of the organism of interest using inhibitors added in the culture media

Answer 7

selective cm

Question 8

contains color indicators as a result of product produced be a chemical reaction in the components of media such as glucose.

Answer 8

differential
