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 کاملcatalase-negative staphylococcus aureus isolated from a diabetic foot ulcer
we report a catalase-negative staphylococcus aureus isolated from a 56-year-old male diabetic patient with foot ulcer who attended our surgery ward. species identification was confirmed by gram staining, standard biochemical tests and pcr amplification of the nuc and fem genes. antibiotic susceptibility showed that the strain was sensitive to imepenem, chloramphenicol, amoxicillin, vancomycin a...
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 کاملClinical Staphylococcus aureus isolate negative for the Sa442 fragment.
The Sa442 DNA fragment, originally described by Martineau et al. (3), is a popular DNA target for identification of Staphylococcus aureus by PCR (2–6). Several PCR-based assays targeting this DNA fragment alone or in combination with a mecA PCR for identification of a methicillin-resistant S. aureus have been described (3, 4). Apart from having been established as being unique for S. aureus, th...
