FIG. 1.

Macrorestriction patterns (SmaI-digested genomic DNA) for 25 isolates of vanA-positive, high-level glycopeptide-resistant enterococci from clinical material from hospitalized patients and from fecal samples from outpatients (top panel). For the 21 vanA-positive E. faecium isolates in this group, the derived dendrogram (see the work of Claus et al. [3]) is presented (bottom panel). For the assignment of strains to lanes and for further characteristics of the strains, see Table 2. Lanes 1 to 21 are the results for the E. faecium isolates, lane 22 is the result for an E. durans strain, and lanes 23 to 25 are the results for E. faecalis strains. Lanes M, molecular size markers (strain S. aureus NCTC 8325).
