FIG 7 .

YB variants form gastric colonies. BALB/c mice were infected orally with YB variant B. pseudomallei and euthanized at day 66 for mouse 3 and day 30 for mouse 5. Stomach tissues were fixed and stained with FISH probes. B. pseudomallei was labeled red, enteric bacteria were labeled green, and DNA was stained blue (DAPI). (A) Images at ×200 final magnification. (B) Images at ×1,000 final magnification. (C) Control image stained with the irrelevant FISH probe (green and red) and DAPI (blue) and captured at ×200 final magnification. (D) Sites of B. pseudomallei colonization indicated with green boxes on a representative stomach image.
