  • a NY, New York; CA, California; TN, Tennessee; LA, Louisiana; IA, Iowa.

  • b spa and coa types are arbitrarily assigned for each unique sequence identified. Repeat codes are derived from organization of individual repeats (random alphabetical code). To make the notation shorter, letter codes ending with the digit “1” have been simplified by removing the number. It should be noted that two isolates were assigned separate spatypes (48 and 59), despite an identical repeat pattern. They contained a sequence polymorphism in a flanking region that is normally conserved (not shown).

  • c spa and coa groups are organized based on sequence alignment and congruence of thespa and coa repeat similarity. The assignment of a particular spa or coa group (A, B, C, and D) was based on the reported spa repeat similarity groupings of New York City MRSA (Shopsin et al. [13]).
