*Patients ordered by date of specimen collection. Isolates from patients B and H have sequence types previously documented in Southeast Asia. BTFC, B. thailandensis–like flagellar gene cluster; MALDI-TOF MS, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry; MLST, multilocus sequence typing; NA, not applicable; QLD, Queensland; ST, sequence type; YLF, Yersinia-like fimbrial gene cluster.
†Molecular detection only; no isolate recovered.
