Question

Explain the best physical and mechanical methods for microbe elimination. Which microbe forms are the most resistant to destroy, explain your answer.

Answer 1

In health-care sector microbes are present everywhere besides the area being very clean to see.

The best physical method to eliminate microbes are

• Heat:Moist heat (Autoclave)Dry heat (Incineration,hot air oven)
• Filtration :biological fluid filtration (Seitz filter,porcelain filter )
• Radiation :Ionising radiation (X Ray, gamma rays,electron beam radiation) non Ionising radiation (UV rays)

The microbe forms which are most resistant are

• Gram positive bacilli group
• Bacillus anthracis and cereus
• Bacterial endospore

Staphyllococcus is one of the most resistant bacteria in the healthcare filed. Thus is because of its resistance to the medication and when occurs for second time leads to high resistance.

The mechanical methods to remove microbes are

• Degermation
• Sterilization is the best method to kill any form of endospore
• Filtration of blood products
• Maintaining sanitation at work place
