Corneal ulcer - gram stain. Corneal scrapings were taken from a 67 yr old farmer presenting with a corneal ulcer of the right eye. A piece of vegetable matter was embedded in the cornea and scrapings were done. Gram stain (500x magnification) showed numerous septate hyphae. Cultures grew a small amount of A fumigatus.
