Figure 6

Serial sampling experiment to investigate bacterial dissemination in blood, spleens, and lungs of C57BL/6 mice at different challenge doses of aerosolized Burkholderia pseudomallei strain ATS2021, the causative strain in an outbreak of 4 cases, 2 of them fatal, in the United States in 2021. C57BL/6 mice were estimated to have inhaled various doses on day 0. A subset of mice was then deeply anesthetized for a terminal blood collection, euthanized, and then the spleens and lungs were removed to determine the bacteriologic burden in each organ at each time point indicated. Bacterial counts are shown for whole blood (A–C), spleen homogenate (D–F), and lung homogenate (G–I). N = 4 for each time point. The CFU burden is shown for each mouse; the geometric mean is depicted with the horizontal bar. Limit of detection is ≈100 CFU/mL of blood and 5 CFU/organ.
