Co-infection of the human cornea with Stenotrophomonas maltophilia and Aspergillus fumigatus

Purpose. To report a case of corneal co-infection of Stenotrophomonas maltophilia and Aspergillus fumigatus. Methods. We describe a culture and biopsy proven infectious keratitis with a large, brown. round anterior chamber mass attached to the endothelium. Results. Stenotrophomonas maltophilia was cultured from external scrapings of a corneal ulcer and septate hyphae were stained with Gomori's methenamine silver(GMS) stain along the wall of the excised intracameral mass, Aspergillus fumigatus was cultured from the mass and pus pockets developed along the corneoscleral incision for removal of the mass. Conclusion. Co-infection of cornea with Stenotrophomonas maltophilia and Aspergillus fumigatus with existence of a large, brown, smooth-surfaced mass in the anterior chamber makes this case unique and interesting.
