Each ApaI, SacII, and SmaI PFGE pattern was assigned a letter and number designation (A 26 to A 50, C 8 to C 21, and S 26 to S 37). PFGE patterns have previously been assigned to isolates from other areas in the United States (reference 23 and unpublished data). Isolates having patterns which differed from these patterns by one to three bands were considered closely related and grouped into subtypes defined by subscripts (A261, A262, C81, etc.). Subscript 1 means one band added to the pattern, subscript 2 means one band deleted from the pattern, subscript 3 means two bands added or deleted, and subscript 4 means a three-band difference (23, 31).
