CXCL8 and infection: IL-8 transcripts were detected 8 h post infection (x = 71.50 ± 30.92) and significantly increased on days 2 (x = 112.17 ± 25.33, p = 0.005), 4 (x = 203.09 ± 58.05, p = 0.01), and 6 (x = 94.22 ± 27.89, p = 0.02) after challenge with the overall highest fold change on day 4 (Figure 3F).
