Susceptibility of Acanthamoeba to soft contact lens disinfection systems.
Members of the genus Acanthamoeba are increasingly recognized as agents of indolent, chronic, infectious keratitis. Recently, Acanthamoeba corneal infection has been reported in some persons who wear soft contact lenses. In this study, three "heat" and three "cold" soft contact lens disinfection systems were tested according to the manufacturers' instructions against Acanthamoeba castellanii an...
متن کاملAcanthamoeba keratitis in a soft-contact-lens wearer.
Acanthamoeba keratitis is an uncommon but potentially devastating complication of contact lens wear. We present a case of Acanthamoeba keratitis in a soft-contact-lens wearer successfully treated with long-term medical therapy and penetrating keratoplasty. To our knowledge this is the first case of Acanthamoeba keratitis diagnosed in Canada.
متن کاملAcanthamoeba polyphaga strain age and method of cyst production influence the observed efficacy of therapeutic agents and contact lens disinfectants.
The effects of age in culture and the type of medium used for induction of Acanthamoeba polyphaga (Ros) cysts on susceptibilities to polyhexamethylene biguanide (PHMB; 3 micro g/ml), chlorhexidine digluconate (30 micro g/ml), myristamidopropyl dimethylamine (20 micro g/ml), H(2)O(2) (3%), and two multipurpose contact lens solutions (MPS-1 and MPS-2, based on 1 micro g of PHMB per ml) were exami...
متن کاملContamination of contact lens storage cases by Acanthamoeba and bacteria.
In order to identify possible risk factors for microbial keratitis the storage cases for contact lenses of 102 asymptomatic lens wearers were tested for contamination by bacteria and free-living amoebae. Of this group 43 had significant counts of viable bacteria and only 40 had negligible counts. Seven had contamination by acanthamoebae, of whom six also had significant bacterial counts. These ...
