Figure 2 Laboratory characterization of the Burkholderia pseudomallei ST271 isolate(A) Bacterial culture of the isolate on Luria-Bertani agar showed circular, dry, smooth colonies with a grayish-white to pale yellow appearance after 48 hours of incubation. (B) Bacterial culture of the isolate on Burkholderia cepacia selective agar revealed circular, convex, gray to white metallic colonies with a yellow color change in the agar. (C) Gram staining of the isolate revealed gram-negative bacilli with a characteristic bipolar “safety-pin” appearance. (D) Bacteriophage susceptibility testing demonstrated lysis of the isolate at a titer of 106 plaque-forming units (PFU)/mL using phage vB_BpP_HN01.
