Molecular characterization of a catalase-negative methicillin-susceptible Staphylococcus aureus subsp. aureus strain collected from a patient with cutaneous abscess.

ABSTRACT: We describe a cutaneous abscess caused by catalase-negative methicillin-susceptible Staphylococcus aureus subsp. aureus in a patient who was concomitantly colonized with virulent USA300 methicillin-resistant S. aureus (MRSA). Sequencing of the katA gene demonstrated a thymine insertion leading to a frameshift mutation and premature truncation of catalase to 21 amino acids.
