Flora literally means flowers. This word is used for micro organisms in the large intestine. They play very important role in your body. You can not survive for long without this flora. They produce few important vitamins like vitamin K. Some times these normal flora is killed by the use of broad spectrum antibiotics. The patient get the condition called as pseudomembranous colitis. Patient can die of loose motion in this case, unless promptly and properly treated. This fact highlights the importance of the micro flora. Such type of bacteria are present on your skin also. At times they are replaced by the abnormal bacteria. The person emits body odour. His social life is adversely affected in that case.
Normal skin flora is a combination of many types of micro-organisms, including bacteria, viruses and yeast. When a wound occurs, some "normal flora" are introduced into the wound, especially in a penetrating wound such as a stabbing or shooting. When a wound culture is performed, the pathologist looks for "normal flora" which could become pathogens if the organisms begin to multiply, especially since those organisms of the normal flora are now in a place they should not normally be (i.e. transferred from the skin to inside the body, in a blood-rich environment). The pathologist also looks for other pathogens, such as the once-normal flora of the assailant or perpetrator which could infect the new host (the person with the wound).
normal flora
how does residental normal flora protect the body against pathogens
The host cell does not benefit from having a virus. The virus usually kills it.
A doctor will determine bacterial infections. There are normal flora in the body and a shift in this flora could suggest infection.
Yes, usual flora, normal flora, and typical flora are all normal results.
there ara no microbial normal flora in the csf
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.

normal flora
Micro-flora or microbiotas benefit humans by using up most nutrients before the bad microflora does. By doing this the bad micro-flora cannot grow out of control and causing damage.
Normal microbiota
In general, your "normal" skin flora protect you from "rogue" flora which might do you harm.
how does residental normal flora protect the body against pathogens
yes
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.
