what placessurfaces can you describe where you can NOT find

what places/surfaces can you describe where you can NOT find bacteria?

Solution

The places/surfaces where we cannot find bacteria are described as \"sterile regions or sterile areas.\" For example, the fluids present in and round the major organs are sterile in the human body. They include the blood, cerebrospinal fluid, peritoneal fluid, pleural fluid, pericardial fluid, vitreous fluid and fluids in the joints.

The sterile field is the area, which is maintained free of microorganisms to avoid the occurrence and spread of infections to the patients under medical care or to the healthy people. It is important to sterilize everything in the surgery division because the instruments may act as carriers of microorganisms. Most of the hospital-acquired infections are due to the inefficient sterilization methods and spread of resistant strains of microbes. Staphylococcus aureus is one of the most common organism that causes hospital-acquired infections.

Standard precautions are the sterilization procedures practiced to control and or prevent the spread of infections by means of different media such as blood, body fluids, mucous membranes, etc.
