Interpretive Summary:

Technical Abstract: The effects of Salmonella enteritidis vaccination on the host cellular immune response was evaluated. Chickens were vaccinated subcutaneously with killed S. enteritidis vaccine at the ages of 3 and 5 weeks. After vaccination, serum samples were collected for 3 weeks for the evaluation of IFN- and IL-2 levels. The IFN- level was significantly (p<0.05) higher in the vaccine group at 7, 11, 14, and 21 days post vaccination (dpv) whereas the IL-2 level was higher at 14, 18, and 21 dpv. Therefore, killed S. enteritidis vaccine induce important chicken cytokines which are involved in the elimination of the intracellular Salmonella.
