  • a All strains have been previously assigned to the “pediatric MRSA clone” based on PFGE patterns, ClaI::mecA patterns, and ClaI::Tn554 insertion patterns (19).

  • b Strain letter codes reflect strain origins (hospital or country) as follows: HDE, Hospital Dona Estefânia, Lisbon, Portugal; HPV, Hospital Pulido Valente, Lisbon, Portugal; IPO, Instituto Português de Oncologia, Lisbon, Portugal; HUC, Hospital da Universidade de Coimbra, Coimbra, Portugal; VNG, Hospital de Vila Nova de Gaia, Vila Nova de Gaia, Portugal; FFP, Faculdade de Farmácia do Porto, Oporto, Portugal; RJP, Instituto Dr. Ricardo Jorge, Oporto, Portugal; HSA, Hospital de Santo António, Oporto, Portugal; COB or CLB, Colombia; ARG, Argentina; BM, New York Hospital Medical Center of Queens, New York, NY.

  • c Country names are abbreviated as follows: Pt., Portugal, Cob., Colombia; Arg., Argentina.

  • d spa sequence repeats are given according to the nomenclature proposed by B. N. Kreiswirth and colleagues (20).

  • e spa types assigned by Egenomics software (B. Kreiswirth and S. Naidich, personal communication).

  • f spa types assigned by Ridom software (5).
