Enhancement of Innate Immunity in Common Carp Cyprinus carpio Using local Probiotic

The objective of this study was to determine the effect of four levels of local probiotic comparedwith commercial probiotic on immune status of common carp Cyprinus carpio as biologicalcontrol. One handared and eight speciement of Cyprinus carpio average weight of 57.85±0.3g werefed during 42 days at 0.05,0.1,0.5 and 0.75mg local probiotic per Kg diet compared with 2mgcommercial probiotic per Kg diet in comparison with the control group without additive. Thephagocyctic index of blood macrophages, reduction of nitrobluetetrazolium (NBT) by radicaloxegen produce from neutrophils cell ,and alternative complement pathway (ACP) activities wereevaluated. A positive correlation was found between the levels of phagocytosis,nitrobluetetrazolium index and alternative complement pathway activities in blood and the levelof inclusion of local probiotic compared with commercial probiotic and control group.
