Co-isolation of genetically distinct Burkholderia pseudomallei strains from a single patient in North Queensland

While investigating colony morphology variation (CMV) within clinical isolates of Burkholderia pseudomallei (Bp) isolated from a single infection, we identified two distinct strains (based on their multi-locus sequence type) from Bp TSV292. Simultaneous co-infection is rare, previously reported in only 2 of 133 cases. Here, we present the first comprehensive multi-omics characterization of co-infecting Bp strains isolated from a single infection at a hospital in Townsville, Australia in 2018. This finding impacts the design of future diagnosis and treatment of Bp.
