Analysis of proinflammatory cytokine/chemokine profiles during the acute phase of infection between days 14 and 16 post challenge showed marked increases of G-CSF, GM-CSF, IL-1β, IL-4, IL-8, IL-12/23 (p40), IL-18, MCP-1/CCL2, SCD40L, TGF-α, and VEGF (Figure 5 and Figure S3). This evidence concerns the gene IL1B and infection.
