Answer 2

Answer:

(C) In the sterilization process, the spore of Bacillus stearothermophilus is considered a control.

Explanation:

• Bacillus stearothermophilus is a thermophilic bacteria that can thrive at temperatures of 65 degrees Celsius and higher. The spores are used to test autoclave operation since they are heat resistant.
• Sterilization is the process of removing all living organisms from an object, including viable spores. Only the use of calibrated biological markers can ensure sterilization quality control.
• Bacillus stearothermophilus spores impregnated on chromatography paper strips are separately inserted into envelopes as indicators. These organisms are more resistant to heat than other vegetative bacteria and viruses, making them harder to eradicate.
• As a result, if they are sterilized, it is presumed that all other life forms are similarly sterilized.
• This is the test that is regarded as the most sensitive in determining an autoclave's efficiency.
