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 from 1990, lane 15 from 1993, lanes from 1994, and lanes from 1995 (see Table 1). λ is the Lambda Ladder PFG Marker.

3. 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 from 1990, lanes 14 from 1993, lanes from 1994, and lanes from 1995 (see Table 1). M is the 100 Base-Pair Ladder from Pharmacia Biotech (Stockholm, Sweden).
