Figure. Pulsed-field gel electrophoresis (PFGE) patterns of SmaI-restricted chromosomal DNA of Streptococcus pyogenes emm44 strains. Lane 1, Bacteriophage Lambda ladder PFGE Marker (New England Biolabs Inc., Beverly, MA, USA); lanes 2–11, PFGE patterns 44-A2, 44-A3, 44-A4, 44-A5, 44-A6, 44-A7, 44-A8, 44-A, 44-B, and 44-A1 of emm44 unrelated control strains; lanes 12–26 and 28–34, 22 identical 44-A1 PFGE patterns shared by the tetracycline-resistant outbreak isolates; lane 27, PFGE pattern 44-A5 of the nonclonal emm44 strain isolated during the same outbreak, which differs by 4 bands from the pattern 44-A1.
