Saccharomyces cerevisiae Cell wall Effects on Immunological Response Of Broiler Chicks that Infected with Listeria monocytogenes

Abstract

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).
