Effect of oxidative stress on vital indicators of Acanthamoeba castellanii (T4 genotype).

Acanthamoeba has 22 genotypes with the T4 genotype being the main causative agent of amoebic granulomatous encephalitis and keratitis. Because the molecular mechanisms of the immune defenses of neutrophils and macrophages against histoparasites are based on oxidative stress, parasites may rely on their antioxidant systems to preclude immune defenses. Therefore, understanding of the effect of oxidative stress on vital characteristics of Acanthamoeba castellanii (T4 genotype) and the antioxidant defense responses of Acanthamoeba to oxidative status will cast light on immune cell-parasite interactions.
