Expression of IL-8 in MFG, at different time points of infection (12 hpi and 18 hpi) induced by an S. aureus challenge. Abundance of mRNA arising from the gene encoding the pro-inflammatory cytokine IL-8 (yellow bar) is expressed relative (± SEM) to transcripts from CSN3, a specific MEC marker (green bar) and from CD18, a specific marker for macrophages and neutrophils (red bar). * Significance is relative to the fold change in expression taking MFG from milk of the right uninfected half-udder as reference (adjusted p-value < 0.05).
