Sharifinejad et al. observed that keratitis and endophthalmitis SE isolates showed the icaA + , icaD + , is256 + gene profile more frequently (55.5% and 50%, respectively) than isolates cultured from the conjunctiva, nasolacrimal duct, and the eyelid for which the predominant (61%) profile was icaA-, icaD-, is256- [4]. The gene discussed is DFFA; the disease is keratitis.
