Whats the difference between bacterial and acanthamoeba keratitis?

Organism: Bacterial keratitis is the infection of the cornea with one of many of the bacterial invaders of the body. Acanthamoeba is a protozoa which likes to live in the cornea, but fortunately is rare. Bacteria causes acute inflammation with pus, pain and discharge. Amoebas are slow growing, produce a chronic problem resistent to anti-bacterials. See a corneal specialist if you suspect this problem.
