Stenotrophomonas maltophilia Keratitis Related to Therapeutic Contact Lens Misidentified with an Automated Identification System


We present a case of keratitis caused by Stenotrophomonas maltophilia in a therapeutic contact lens user with trichiasis and symblepharon. This keratitis was initially diagnosed as caused by Achromobacter xylosoxidans, but the strain was sent for species confirmation and the isolate was finally identified as S. maltophilia by means of 16S rDNA sequencing. The patient rapidly improved on administration of fortified ceftazidime. Physicians should be aware that the definitive identification of the pathogenic agent and prolonged antimicrobial treatment according to culture sensitivities in keratitis are mandatory as treatment success depends greatly on them.
