Figure 1. Bacterial burden of individual granulomas.

Bacterial burden is represented as the colony forming units (CFU) in logarithmic scale, per granuloma. Greyed area represents sterile granulomas (indicated as log₁₀ 1), which were assigned arbitrary range of values so that all granulomas can be seen in the graph. Each symbol represents a granuloma and a color represents granulomas from one animal. Granulomas are grouped as per the clinical status of the animal, where those animals that were infected for ∼11 weeks are in shades of green, active disease in shades of warm colors and latent infection in shades of cool colors. (****: p<0.0001, Dunn’s multiple test comparison).
