Whole-genome core orthologous single-nucleotide polymorphism (SNP) phylogeny of sequence type 562 Burkholderia pseudomallei isolates from a patient with melioidosis and from environmental sampling at the patient’s residence, Darwin, Northern Territory, Australia. MSHR4515 (MLST database identifier, http://bpseudomallei.mlst.net/) was a blood culture isolate from the index patient, identified as patient (P) 692 (P692, arrow). Analysis of isolates from 13 other patients with sequence type 562 are also shown (identifiers begin with P). Comparison of data for NPs and for multilocus variable-number tandem-repeat analysis of 4 loci (MLVA-4) types (shown in parentheses) supports the hypothesis that P692 was infected from environmental B. pseudomallei at his residence. Consistency index = 1.
