Phylogenetic Analysis of Stenotrophomonas spp. Isolates Contributes to the Identification of Nosocomial and Community-Acquired Infections

Figure 1

Neighbor-joining phylogram of 47 Stenotrophomonas spp. clinical strains based on 7 concatenated genes. Neighbor-joining phylogram (1000 bootstrap replications, p-distance model) derived from concatenation of atpD, guaA, gapA, nuoD, ppsA, recA, and rpoA gene sequences. Phylogenetic groups and subgroups are indicated by A, B, B.I, B.II, B.III, B.III.1, B.III.2, and B.III.3. The numbers at branch nodes represent bootstrap values ≥50.
