Similar results were found in studies by Deng et al. [46] and Gong et al. [16], who found that Lactobacillus plantarum could decrease the levels of IL-1β, TNF-α, and IFN-γ, and increase the IL-10 level in broilers under Listeria monocytogenes infection or Clostridium perfringens infection. Here, IL1B is linked to infection due to clostridium perfringens.
