Achromobacter xylosoxidans is a bacterium not previously reported in a corneal infection. We present a case of infectious keratitis caused by this organism, occurring 1 month following penetrating keratoplasty.
Identification of the organism was accomplished by staining, culture, and sensitivity testing of the corneal scraping obtained from the involved area. The infection responded to subconjunctival ticarcillin, piperacillin eye drops, and I.V. azlocillin.
Complete healing with a resultant corneal opacity involving mostly the anterior and middle stroma was achieved 1 month later.
A. xylosoxidans should be considered as a potential pathogen in instances of early postkeratoplasty infectious keratitis.
