mRNA transcripts of endometrial a) IL-1β , b) IL-6 , c) IL-8 , d) TNF-α , e) SAA , f) IL-10 , g) IL-1ra and h) IL-1β:IL-1ra in mares after intrauterine infusion of E. coli. The gene expressions are normalized to β-actin and displayed as n-fold change to estrous baseline levels (mean ± sem). Asteriks indicate significant differences between resistant (white bars) and susceptible (grey bars) mares. *p < 0.05. Different letters above the bars indicate significant differences between the time points within the group of mares (p < 0.05).
