Achromobacter xylosoxidans corneal ulcer in a therapeutic soft contact lens wearer.Cornea. 1989 Dec; 8(4):267-9.C
Achromobacter xylosoxidans is an opportunistic organism that is usually seen in immunocompromised or immunosuppressed patients. It is an aerobic gram-negative rod, often confused with other more commonly seen gram-negative bacteria such as Pseudomonas aeruginosa. The organism is usually sensitive to extended spectrum penicillins such as carbenicillin and usually resistant to aminoglycosides and first generation cephalosporins. We wish to describe a corneal ulcer from A. xylosoxidans that developed in a patient wearing a therapeutic soft contact lens. The patient did not have a preexisting microbial keratitis and was not receiving corticosteroid therapy.
