Eimeria tenella: Expression profiling of toll-like receptors and associated cytokines in the cecum of infected day-old and three-week old SPF chickens

► Provide new data of dynamic changes of TLRs during Eimeria tenella infection. ► Provide new data of dynamic changes of involved cytokines during infection. ► Investigate gene expression of the caecum in the first 72 h post infection. ► Observe the responses of TLRs and cytokines in one-day-old and three-week-old chickens.
