If human skin and the body had no flora and was, essentially, a "sterile environment" without any microorganisms, then every time contact was made with a micro-organism the body could become ill. The normal flora allows the body to recognize microorganisms on objects we touch, hands we shake, germs we come into contact with, but permits our bodies to not react to every germ as an attack. Without normal flora, our bodies would be susceptible to every germ, leading to frequent and repeated infection.
Also, in some cases, normal flora helps the body carry on normal functions. For example, E-Coli helps process what we've eaten and helps in the formation of stool (bowel movement).
Human (normal) gut flora are bacterium largely beneficial to our health and nutrition. These flora are regarded to produce Vitamins B & K. Normal flora also play an important role from birth in the human immune system.
The "normal flora" in the alimentary system is necessary for optimum good health because it helps break down food properly. Without these bacteria, digestion is often compromised.
Yes, usual flora, normal flora, and typical flora are all normal results.
The normal flora varies by body region. For example, the skin has bacteria like Staphylococcus epidermidis, while the gut has bacteria like Bacteroides and Firmicutes. These normal flora help protect against pathogenic invaders and play a role in maintaining health.
Another term for normal flora is indigenous microbiota or resident flora.
health is as if not more valuble than wealth
Health, care, love, affection, and nurturing.
Normal flora are microorganisms that permanently reside in or on the body without causing harm, known as resident flora. Transient flora are temporarily present on the body and can be acquired through contact with the environment or other individuals. While resident flora play a role in maintaining health by competing with harmful bacteria, transient flora can potentially cause infections if they enter the body.
You said that in your answer too. As the flora is normal, there is no harm
Normal flora cannot cause a "disease". But if normal flora is disrupted it can become a pathogen and then cause infection. Some diseases, like diabetes, can disrupt normal flora and cause infection, especially yeast infections on the skin or in the vagina of women.
In general, your "normal" skin flora protect you from "rogue" flora which might do you harm.
Normal flora, or the microbiota, play several beneficial roles in human health. They help maintain the balance of microbial communities, preventing harmful pathogens from colonizing the body. Additionally, they aid in digestion and nutrient absorption, produce essential vitamins like vitamin K and certain B vitamins, and contribute to the immune system by enhancing immune responses and protecting against infections. Overall, normal flora support overall health and homeostasis within the host.
