Figure 1.

Corneal scrapings from patients with microbial keratitis (Gram stain, x1000) showing (a) capsulated gram-positive cocci in pairs, suggestive of Streptococcus pneumoniae; (b) septate, hyaline fungal filaments; (c) double-walled, polygonal Acanthamoeba cysts; (d) intracellular gram positive, oval, well-defined microsporidia spores with characteristic paracentral or polar dark staining. (e) Shows a slit lamp photograph of a patient with stromal infiltrate of two-month duration with relatively clear surrounding cornea. Corneal scraping of the patient stained with Gram stain showed (f) unstained bacilli ( × 1000) that were found to be acid fast by (g) Ziehl Neelsen stain ( × 1000). A significant growth of Mycobacterium fortuitum was seen in culture on (h) blood agar of the corneal scraping.
