there ara no microbial normal flora in the csf
Normal microbiota
Flora exists in various parts of the human body, in both men and women. Vaginal flora, or microbiome, in normal levels has no disadvantage. It helps the vagina stay "normal", clean and healthy.

It is normally sterile--there is no flora unless it is introduced to the bladder. That's what causes a 'bladder infection'!
Normal body flora is generally helpful to the organism. In fact having normal body flora occupies space and resources that could otherwise be utilized by pathogens. However, some normal body flora can be harmful if the microbe enters an area of the body that it would not normally be found and can cause infection. These bacteria are known as opportunistic pathogens.
Yes, usual flora, normal flora, and typical flora are all normal results.
No. CSF like blood should be sterile.

Swelling of the meninges may interfere with the normal absorption of CSF by blood vessels, causing accumulation of CSF and damage from the resulting pressure on the brain.
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
Scarring of the meninges may result in obstruction of the normal flow of CSF, causing abnormal accumulation of CSF.
Normal CSF should contain no infection-fighting cells (white blood cells), so the presence of white blood cells in CSF is another indication of meningitis.
Normal microbiota
In general, your "normal" skin flora protect you from "rogue" flora which might do you harm.
