In vitro susceptibility patterns of methicillin-resistant Staphylococcus aureus and coagulase-negative Staphylococcus corneal isolates to antibiotics.

Purpose: To determine the in vitro susceptibility of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant coagulase-negative Staphylococcus (MRCNS) isolates to various antibiotics.

Methods: All cases of bacterial keratitis caused by Staphylococcus species during 2006 and 2007 were identified. The isolates were divided according to species and susceptibility to methicillin into 4 groups: methicillin-susceptible S.

Post-traumatic fungal keratitis caused by Carpoligna sp.

Purpose: To report the first case of fungal keratitis caused by presumed Carpoligna species.

Methods: A 37-year-old gardener sustained a full-thickness, stellate corneal laceration while cutting wood outdoors with a circular saw. Two months after surgical repair, he developed a severe infectious keratitis with descemetocoele at the apex of the original stellate laceration.
