WebApr 30, 2015 · Methicillin-resistant Staphylococcus aureus (MRSA) is a significant cause of hospital-associated pneumonia (HAP). The rapid identification of MRSA would be beneficial for early diagnosis. The study aimed to evaluate a multilocus, fluorescence-based PCR assay based on the detection of mecA and nuc genes for identification of S. aureusin lower … WebSCCmec, or staphylococcal cassette chromosome mec, is a mobile genetic element of Staphylococcus bacterial species. This genetic sequence includes the mecA gene coding for resistance to the antibiotic methicillin and is the only known way for Staphylococcus strains to spread the gene in the wild by horizontal gene transfer.

WebJan 17, 2024 · Molecular Confirmation of Methicillin Resistance Using PCR, we tested for the presence of methicillin resistance genes mecA and mecC ( 27, 28) as well as mecB. DNA sequences of PCR oligonucleotides are given in Table 1. Oligonucleotides for mecB were made on basis of the plasmid pMCCL2 of M. caseolyticus (GenBank accession no. … WebApr 10, 2024 · The rapid emergence of MRSA raised the hypothesis that mecA was already present in the staphylococcal gene pool prior to the introduction of methicillin. In fact, a ubiquitous homologue named mecA1, with 80% nucleotide identity to mecA has been identified in the primitive coagulase-negative Staphylococcus sciuri [ 15 ].
