  3. cSeventy-four isolates from Australia, 1 isolate from Asia and 1 isolate of unknown origin
  4. dAvailable existing spectra from the Townsville study were used and bacterial isolates were not re-cultured
  5. eIndependent isolates that were not used in the SuperSpectra creations
  6. fMisidentified as Sphingobacterium multivorum (91.5% ID) another spot of the same isolate was correctly identified as B. pseudomallei (99.9% ID)
