Identical MALDI TOF MS-derived peak profiles in a pair of isogenic SCCmec-harboring and SCCmec-lacking strains of Staphylococcus aureus

Journal of Infection, 2012
MALDI-TOF MS-based peak differences in oxacillin-resistant Staphylococcus aureus and oxacillin-susceptible S. aureus isolates have been described previously. Unfortunately, these isolates were not isogenic with respect to their mecA gene. Ours is the first to use a SCCmec-harboring parent and a SCCmec-lacking daughter strain, with the same genetic ...

Staphylococcal Cassette Chromosome mec (SCCmec) Analysis of MRSA

2013
Methicillin-susceptible S. aureus (MSSA) changes to methicillin-resistant S. aureus upon the acquisition of Staphylococcal Cassette Chromosome mec (SCCmec), a genomic island that encodes methicillin resistance. All SCCmec elements reported to date share four common characteristics: (1) carrying the mec gene complex (mec); (2) carrying the ccr gene ...

Staphylococcal Cassette Chromosome mec (SCCmec) Analysis of MRSA

2019
Methicillin-susceptible S. aureus changes to methicillin-resistant S. aureus (MRSA) upon the acquisition of staphylococcal cassette chromosome mec (SCCmec), a genomic island that encodes methicillin resistance. SCCmec elements in S. aureus are classified into different types based on the combination of mec gene complexes and ccr gene complexes, which ...

Correlation between type IIIA CRISPR–Cas system and SCCmec in Staphylococcus epidermidis

Archives of Microbiology, 2021
A subculture of S.epidermidis strain ATCC35984 that is amenable to genetically manipulate was occasionally found in our laboratory. This mutant exhibited susceptibility to methicillin in contrast to its parent strain. To unveil the underlying mechanism, whole-genome sequencing of the mutant was performed.

The Characterization of mecA Gene and SCCmec Typing in Clinical Samples of MRSA

Science Letters, 2019
MRSA is a major pathogen worldwide and its infections are associated with increased morbidity and mortality, in comparison with other S. aureus infections. The study was designed to characterize the mecA gene and staphylococcal cassette chromosome (SCCmec) in methicillin resistance S. aureus (MRSA). A total of 20 presumptive S.

SCCmec-associated psm-mec mRNA promotes Staphylococcus epidermidis biofilm formation

Antonie van Leeuwenhoek, 2016
Biofilm formation is considered the major pathogenic mechanism of Staphylococcus epidermidis-associated nosocomial infections. Reports have shown that SCCmec-associated psm-mec regulated methicillin-resistant Staphylococcus aureus virulence and biofilm formation. However, the role of psm-mec in S. epidermidis remains unclear.

Structural Determinants of SCCmec Recombination in Staphylococcus aureus

Methicillin resistance in Staphylococcus aureus emerges through acquisition of a mobile genetic element named staphylococcal cassette chromosome mec (SCCmec). SCCmec contains the mecA gene, which confers resistance, and the ccrA/ccrB or ccrC operons encoding large serine recombinases that integrate and excise the element.

Staphylococcal cassette chromosome mec (SCCmec) typing of methicillin-resistant Staphylococcus aureus strains isolated in 11 Asian countries: a proposal for a new nomenclature for SCCmec elements.

Antimicrobial agents and chemotherapy, 2006
A description of staphylococcal cassette chromosome mec (SCCmec) elements carried by 615 methicillin-resistant Staphylococcus aureus (MRSA) strains isolated in 11 Asian countries is reported, and a novel nomenclatural system based on their structures is proposed.
