JudyNormal microbiota are permanently found in a specific body site, while transient microbiota are temporarily present and do not normally establish a long-term residence. Normal microbiota play important roles in host health and immune function, whereas transient microbiota can vary depending on factors like diet, hygiene, and environment.

If most of the normal microbiota and transient microbiota aren't harmfulthen why must hands be scrubbed before surgery?
Scrubbing hands before surgery helps to remove transient microbiota that could potentially be harmful if introduced into a surgical wound. While most of the normal and transient microbiota are not harmful under normal circumstances, they can become opportunistic pathogens in certain situations, such as during surgery when the body's natural defenses are compromised. By scrubbing hands, the risk of introducing harmful bacteria into the surgical site is reduced, helping to prevent infections.
What is another term for normal flora?
Another term for normal flora is indigenous microbiota or resident flora.
Is streptococcus normal microbiota of the skin?
No, Streptococcus is not considered a normal microbiota of the skin. It is more commonly associated with the respiratory and gastrointestinal tracts.
What is the role of normal microbiota?
Normal microbiota play a vital role in maintaining the health of the host by competing with harmful pathogens for nutrients and space, aiding in digestion and nutrient absorption, and regulating the immune system. They also help prevent colonization by pathogenic bacteria through a concept called "colonization resistance."
What is microbiota?
Normal Microbiota are the non-pathogenic bacteria/micro-organisms that reside in or on a human body. They don't normally cause infection, as they live in symbiosis with the human body - unless they are actually an infectious bacteria, but have already been suppressed by the immune system.
