Figure 3: Staphylococcus keratitis in the New Zealand white rabbit 19 hours after infection. Experimental keratitis was induced by intracorneal injection of 100 colony-forming units of methicillin-resistant S. aureus (clinical blood specimen) according to the method of O’Callaghan’s group [18]. The black arrow indicates the presence of stromal infiltration, and the white arrow indicates the edge of a large corneal epithelial erosion, which was stained with fluorescein for ease of visualization.
