aSpecies: Bp, Burkholderia pseudomallei; Bt, B. thailandensis; Bo, B. oklahomensis; Bm, B. mayonis sp. nov.; Bs, B. savannae sp. nov. All strains were positive for the assimilation of adipate, caprate, citrate, gluconate, glucose, malate, mannitol, mannose, N-acetylglucosamine, and phenylacetate; and all strains were negative for glucose (acidification), urea, and PNPG (these data not shown).

bData obtained from a previous study (34).

c+, positive reaction; -, negative reaction.
