FIG 1.

Range of inflammation among macaque species. Three-dimensional volume renderings of PET-CT scans of infected animals at 12 weeks postinfection are shown. Animals in all three species have a wide range of lung inflammation, ranging from minimal (represented as “Best”) to extensive (represented as “Worst”). Green arrows show thoracic lymph nodes. All other pathology seen on these scans is within the lungs. All of the animals depicted here have granulomas, although small lesions are not visible on these images.
