异源益生菌株抗病原体作用差异性比较

Difference comparison of anti- pathogen effect of Heterologous probiotics

为探索异源益生菌株抗病原体作用差异性,对猪源益生菌、鸡源益生菌和狐貉源益生菌进行抗TGEV病毒活性和抑制大肠杆菌O78及致病性金黄色葡萄球菌作用测定。结果表明,益生菌株抗病原体作用存在来源差异性和种属差异性,当益生菌株来源与病原体来源相同时,益生菌表现更强抗病原体活性。

To explore the differences of anti-pathogen effects of Heterologous probiotics,we measured the anti-TGEV activity, inhibition to E. coli 078 and inhibition to pathogenic staphylococcus of probiotics from swine, from chicken, from fox and racoon dog. The results showed that probiotic strains played a probiotic role according to probiotic strains and species-specific differences. When the source of pathogens and probiotics were the same, the probiotics showed the most significant anti-pathogen effect.
