In addition, Li et al. [37] demonstrated that inoculation of S. gallolyticus in duckling induced macrophage necroptosis in spleens by bacterial infection and increased the expression levels of IL-6, and that decreased population of S. gallolyticus achieved in response to dietary oregano powder has a negative relationship with the increase of anti-inflammatory cytokine IL-10 [38]. Here, IL6 is linked to bacterial infectious disease.
