The objects of this study were to determine the effect of Saccharomyces cerevisiae cell wall (SCCW) to induce immunological response of Broiler chicks that infected with Listeria monocytogenes . SCCW was administrated to chicks by adding 30 gm / 100 kg feed. A 30 broiler chicks were distributed into 3 treatments ( 10 chicks/ treatment) which were: T1 : control group for both experiment fed on (SCCW). T2 : chicks fed 30 gm / 100 kg feed (SCCW) and experimentally infected orally by Listeria monocytogenes 0.1 ml of 1 × 109 CFU /ml. T3 : chicks were experimentally infected orally by Listeria monocytogenes 0.1 ml of 1 × 109 CFU /ml. and study some immunological parameter includes the concentration of  - globulin, albumin, transfferin, H/L ratio, single diffusion test, delayed hypersensitivity reaction (DWR). The result obtained revealed that using (SCCW).increased immune response (cellular and humeral immunity) through increased of lymphocyte and decreased H/L ratio and positive reaction of delayed hypersensitivity also increase the percentage of  - globulin, albumin compared with infected group (T3).
