FIG. 6.
Dendrogram showing six strains (C1 to C6) subcultured for eight passages (P1 to P8), with Cn and Pn indicating the strain and passage number, respectively. No change in the pulsed-field profile could be identified. UPGMA with 1% band tolerance and 1% optimization settings was used as the clustering method. Only DNA profiles obtained after restriction with XbaI are shown.
