MRSA graduation project
Methicillin-resistant Staphylococcus aureus isolate Sam21 (ST6) has a ~2.85 Mb genome with a multidrug-resistant profile driven by the mecA gene and efflux-related resistance genes. Mobile genetic elements indicate strong horizontal gene transfer potential, and phylogenetic analysis shows close similarity to Staphylococcus aureus subsp. aureus N315.Overall, the isolate exhibits high adaptability and epidemiological importance, supporting the need for continued genomic surveillance.
