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

Figure 4

Neighbor-joining phylogram of 52 Stenotrophomonas spp. clinical and environmental strains based on 6 concatenated genes. Neighbor-joining phylogram (1000 bootstrap replications, p-distance model) derived from concatenation of atpD, guaA, gapA, nuoD, ppsA, and recA gene sequences. Phylogenetic groups and subgroups are indicated by A, B, B.I, B.II, B.III, B.IV, B.IV.1, B.IV.2, and B.IV.3. The numbers at branch nodes represent bootstrap values ≥50.
