Strain variations among Streptococcus pyogenes T1—a possible explanation for bacteremia epidemics?  Anders Österlund, Lars Engstrand  Clinical Microbiology and Infection  Volume 4, Issue 6, Pages 316-320 (June 1998) DOI: 10.1111/j.1469-0691.1998.tb00065.x Copyright © 1998 European Society of Clinical Infectious Diseases Terms and Conditions

Figure 1 Comparison of PFGE patterns after Smal cleavage from 24 consecutive blood culture isolates of S. pyogenes T1. Lane 1 is from a strain isolated in 1986, lanes 2 and 3 from 1988, lanes 4-11 from 1989, lanes 12-14 from 1990, lane 15 from 1993, lanes 16-21 from 1994, and lanes 22-24 from 1995 (see Table 1). λ is the Lambda Ladder PFG Marker.

Figure 2 Comparison of RAPD analysis patterns from 23 consecutive blood culture isolates of S. pyogenes T1. Lanes 1 and 2 are from strains isolated in 1988, lanes 3-10 from 1989, lanes 11-13 from 1990, lanes 14 from 1993, lanes 15-20 from 1994, and lanes 21-23 from 1995 (see Table 1). M is the 100 Base-Pair Ladder from Pharmacia Biotech (Stockholm, Sweden).
