A member asked:

How hard does water have to be forced up the nose for the brain eating amoeba n fowleri to infect you?

It doesn't: There is no pressure gradient required for Naegleria fowleri in endemic waters to infect; it migrates when in the trophozoite form after attaching to olfactory axons and into the brain through the cribiform plate.

Agree with Dr. Liang: There have been no reports that excessive force is needed for N fowleri to be transmitted.
