Figure 4From: Gene expression profile suggests that pigs (Sus scrofa) are susceptible to Anaplasma phagocytophilum but control infectionSerum IL-8, IL-1 beta and TNF-alpha levels in experimentally infected pigs. Cytokine levels were determined by ELISA in the sera from infected and uninfected control pigs and infected to uninfected average ± S.D. ratios determined. Results were compared between infected and control pigs by Student’s t-test (*P ≤ 0.05).Back to article page
