Molecular Characterization of a Catalase-Negative Staphylococcus aureus Blood Culture Isolate.
Here we report a catalase-negative methicillin-sensitive Staphylococcus aureus isolate collected from a blood culture. Sequencing through the gene encoding catalase, katA, demonstrated a 2-bp insertion. The resulting frameshift mutation generates a protein that has lost 26 amino acids (aa) at its C-terminal domain.
متن کاملCharacterization of a catalase-negative methicillin-resistant Staphylococcus aureus strain.
We describe an unusual clinical strain of catalase-negative methicillin-resistant Staphylococcus aureus sensu stricto. Sequence analysis of its catalase gene showed 99.60% identities to the catalase genes of the reference strains. A 5-base deletion, however, led to a shift of the nucleotide reading frame and a loss of the enzymatic activity.

متن کاملIsolation and molecular characterization of catalase-negative Staphylococcus aureus from sputum of a patient with aspiration pneumonia.
Staphylococcus aureus produces various virulence factors. The catalase enzyme, in particular, is considered to be involved in oxidative stress resistance, and catalase activity is an important criterion for differentiating staphylococci from streptococci. In this report, we describe the catalase-negative S. aureus strain SH3064, which was isolated from the sputum of a patient with aspiration...
