Staphylococcus aureus (S. aureus), strain SA MER (also referred to as NRS11) was isolated in December 1998 in France from the eye of a 35-year-old female with spontaneous conjunctivitis who had no history of treatment with antimicrobial agents, including glycopeptides, in the preceding three months.

S. aureus, strain SA MER was deposited as a heterogeneous vancomycin-intermediate S. aureus (hVISA) strain, but unlike most hVISA strains, it is susceptible to methicillin. S. aureus, strain SA MER was deposited as resistant to benzylpenicillin; negative for mecA, vanA, vanB, vanC1, vanC2, vanD and vanE; MLST sequencing type (ST) 5; eGenomic spa type 2, eGenomic spa repeats TJMBMDMGMK; Ridom spa type t002. SA MER was the parental strain used to derive strains SA MER-S6 (NRS-12), SA MER-S12 (NRS13) and SA MER-S20 (NRS14) by exposing this strain to increasing levels of vancomycin resulting in the strains growing in the presence of 6 µg/mL, 12 µg/mL and 20 µg/mL vancomycin, respectively.

Each vial contains approximately 0.5 mL of bacterial culture in Brain Heart Infusion broth supplemented with 10% glycerol.
