Figure 4. Increased levels of KC, LIX and MIP-2 during infection with 3348ΔspyCEP.

Thirteen different chemokines were measured in the individual mouse air pouch lavages collected at 4 h (A) and 24 h (B) post-infection with 3348 (white bars) and 3348ΔspyCEP (black bars). Results are shown as means and SEM of one representative experiment using 8 mice per group. Statistical significance was tested by Mann-Whitney U: P<0.01 (**), P<0.001 (***).
