Methods of microbial control
, Introduction to the control of microorganisms
• Control of microorganisms is essential in order to prevent the
transmission of diseases and infection, stop decomposition and
spoilage, and prevent unwanted microbial contamination.
• Microorganisms are controlled by means of physical agents and
chemical agents. Physical agents include such methods of
control as high or low temperature, desiccation, osmotic
pressure, radiation, and filtration.
• Control by chemical agents refers to the use of disinfectants,
antiseptics, antibiotics, and chemotherapeutic antimicrobial
chemicals
, What is Sterilization?
• Sterilization is the process of destroying all living organisms and viruses. A
sterile object is one free of all life forms, including bacterial endospores, as
well as viruses.
• Sterilization can be defined as any process that effectively kills or eliminates
transmissible agents (such as fungi, bacteria, viruses and prions) from a
surface, equipment, foods, medications, or biological culture medium.
