Laboratory investigation of Acanthamoeba keratitis.
Following the diagnosis of Acanthamoeba keratitis in a contact lens wearer, the antimicrobial susceptibility of the clinical isolate and the environmental source of the infection were investigated. Contrary to previous reports, in vitro antimicrobial testing showed that the infecting strain was inherently resistant to propamidine isethionate. Restriction endonuclease digestion analysis of Acant...
متن کاملLaboratory investigation of Acanthamoeba lugdunensis from patients with keratitis.
PURPOSE Species of four Acanthamoeba isolates (KA/E2, KA/E12, KA/E15, and KA/E16) from the cornea of patients with keratitis were identified and their molecular characteristics compared with those of other strains. METHODS Morphologic features of amebic cysts were evaluated with a microscope with differential interference contrast (DIC) optics. Restriction fragment length polymorphisms (RFLP)...
متن کامل[Acanthamoeba keratitis].
Three patients, women aged 69, 25 and 30 years, with refractory keratitis were found to have a rare infection with Acanthamoeba. All wore soft contact lenses. The frequency of Acanthamoeba keratitis increased in recent years. At present, an efficacious antiprotozoal therapy is available, for instance in the form of polyhexamethylene biguanide and propamidine. In cases of refractory keratitis, t...
متن کاملAcanthamoeba keratitis: experience in a non-specialist microbiology laboratory.
Acanthamoeba keratitis is an unusual complication of wearing soft contact lenses: a case was diagnosed by culturing corneal scrapings. Acanthamoeba are tolerant of variations in osmolarity in the culture media. Page's saline, recommended for culture agar plates, can easily be substituted with salines which are suitable for cell culture media, thereby avoiding the cumbersome manufacture of speci...
متن کاملPersistence of acanthamoeba antigen following acanthamoeba keratitis.
AIM To investigate the hypothesis that persistent corneal and scleral inflammation following acanthamoeba keratitis is not always caused by active amoebic infection but can be due to persisting acanthamoebic antigens METHODS 24 lamellar corneal biopsy and penetrating keratoplasty specimens were obtained from 14 consecutive patients at various stages of their disease and divided for microscopy...
