Normal flora is bacteria and yeast normally found on the skin and in every body orifice (or opening, such as the mouth, ears, rectum, vagina). A newborn carries the flora of his/her mother but soon develops his/her own flora. Flora is present on our bodies until we die. We can disrupt the balance of normal flora, such as when women douche too frequently, and thus the microorganisms begin to multiply and become pathogens.
Yes, usual flora, normal flora, and typical flora are all normal results.
Another term for normal flora is indigenous microbiota or resident flora.
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.
yes
The brain and spinal cord have no normal flora, as they are considered sterile environments in healthy individuals.
Yes, normal microbial flora can become virulent or pathogenic if the conditions are right. On outside of body normal flora is harmless, if it was to be ingested it would take the opportunity to do as much damage as possible.
Cerebrospinal fluid (CSF) is typically a sterile fluid, meaning it should not contain any normal flora. The presence of bacteria in the CSF is abnormal and can indicate an infection, such as meningitis.
Streptococcus bovis is not considered a normal part of the bacterial flora in humans. It can be found in the gastrointestinal tract of some individuals, but it is not a common or typical component of the normal flora.
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.
Normal flora is present throughout the body and on all areas of the skin. Every body orifice (opening) contains normal flora: the mouth, ears, vagina, and rectum. E-Coli exists in the intestines. The skin contains a variety of flora that can turn into pathogens under the right conditions.
