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).
