Listeria monocytogenes

 

 

 

 

 

Escherichia coli

 

 

 

 

 

Vibrio cholerae

 

 

 

 

 

Helicobacter pylori

 

 

 

 

 

 

Question 4 (3.1)

 

The graph below shows that bacteria have an exponential rate of growth.

Interpret growth rates derived from practical work, investigating factors affecting microbial growth.

 

 

Bacteria are said to grow exponentially.  Escherichia coli generate (double in number) every 17 minutes and Streptococcus aureus every 28 minutes.

Escherichia coli bacteria have been growing for 12 hours.  If this growth started with a single Escherichia coli bacterium, how many bacteria would there be after 12 hours?

1,500,623,478 Streptococcus aureus were counted on a culture plate. Calculate approximately how long has elapsed since the first bacterium divided.

Question 5 (3.2)

 

Explain the COSHH regulations; include the importance of these regulations when dealing with microbes.

 

Question 6 (3.3)

 

Evaluate why hand hygiene is of the utmost importance for health professionals and service users.

Question 7 (4.1)

 

Evaluate the following sub-culturing techniques:

·       Streak plate inoculation solid-to-solid

·       Streak plate inoculation liquid-to-solid

·       Spread plate solid-to-solid

·       Pour plate liquid-to-solid

·       Inoculating a solid culture -to-liquid

·       Inoculating a liquid culture -to-liquid

Paraphrase citation

Use the citation to the endpoint in each response

stick to OpenStax and Lumen Learning, or A-Level Biology textbooks

Try to give additional specific facts and details like numerical information, specific cellular/histological details. 

Reduced the surrounding wording or opening sentences to instead directly describe or explain versus the question/AC instructions

Extra factual additions to cover a wider array of detail relative to the criteria.
