Q

3 primary categories of culture media

A

NUTRITIVE
DIFFERENTIAL
SELECTIVE

30
Q

Media that support
the growth of many different
microorganisms without
distinguishing genera or species

A

NUTRITIVE

31
Q

allow several different types of bacteria to grow, but also contain compounds that allow microbial genera

A

DIFFERENTIAL

32
Q

are used to select for the growth of a particular “selected” microorganism.

A

SELECTIVE

33
Q

Bacterial culture methods (3)

A

Culture broth
Storing bacterial cells
Nutrient agar

34
Q

Culture in liquid media, also known as a BLANK, gives the bacteria present easy access to the available nutrients compared to static bacterial colonies.

A

Culture broth

35
Q

When looking to store bacterial strains long term, they may be grown up in liquid media. Glycerol is then added, which will prevent complete freezing and consequent lysis of the bacterial cells, permitting their storage at

A

-80 °C.

36
Q

Adding agar to BLANK enables it to be set in petri dishes, as slopes or in plugs.

A

liquid media

37
Q

is useful when you wish to select individual colonies from a mixed culture

A

Solid media

38
Q

Common problems with bacterial culture (5)

A

Contamination

Overgrowth of some species

Antibiotic treatment prior to sampling

Incorrect growth conditions

Non-culturable and slow-growing organisms

39
Q

Good aseptic technique can help to avoid contamination of bacterial cultures.

A

Contamination

40
Q

Some bacterial species grow easily and vigorously

A

Overgrowth of some species

41
Q

In a diagnostic setting, it is important to know if antibiotic treatment has been administered prior to sampling.

A

Antibiotic treatment prior to sampling

42
Q

The use of inappropriate or suboptimal growth conditions may impede or completely prevent the growth of your target strain.

A

Incorrect growth conditions

43
Q

Some bacterial species, even now, cannot be grown in the lab.

A

Non-culturable and slow-growing organisms

44
Q

Applications of bacterial culture (5)

A

Diagnose infection

Genetic manipulation

Epidemiological study

Scale up to enable omics studies
