Acanthamoeba spp. are protozoa which are widespread in the environment. However, only a few species are capable of causing disease in humans. Acanthamoeba are capable of causing eye infections in persons who wear contact lenses or experience eye trauma. It is also capable of causing granulomatous amoebic encephalitis in immune deficient individuals. Acanthamoeba that cause disease are also 'free-living' i.e. they can reproduce in the environment without infecting a host. Those capable of causing disease are referred to as amphizoic amoeba because of their ability to live both free in nature and as pathogens in a host. Acanthamoeba has two stages in its life cycle (cyst and trophozoite). The cyst is the environmentally resistant stage and can survive in the environment for many years. Acanthamoeba feed on bacteria, fungi, other protozoa, and cyanobacteria. They are easily grown on non-nutrient agar plates seeded with Escherichia coli or Klebsiella pneumoniae.
