title: Restriction enzyme analysis of mitochondrial DNA of Acanthamoeba strains isolated from corneal lesions.
abstract: Although Acanthamoeba keratitis has been recognized as one of the important infectious diseases of the cornea, especially in contact lens wearers in recent years, its taxonomy has not been well established. We carried out mitochondrial DNA (mtDNA) analysis of the Acanthamoeba organisms isolated from corneal lesions in four eyes of three patients who had suffered from keratitis. The mtDNA was analyzed by restriction fragment length polymorphism (RFLP) using restriction enzymes Bg/II and EcoRI. The RFLP analyses revealed that the DNA phenotypes of the Acanthamoeba organisms were identical to those of the Ma strain in two patients and to the Castellani strain in one patient.
