Firstly, normal mice was given orally by SM(qd×2d), and the dysbacteriosis were caused in them ,and then they were given orally by STM,these mice were formed experimental salmonellosis models ,finally these salmonellosis models were treated by bifidobacterium ,and count respectively the cfu/g of STM number in the mice excrement during different time of therapy,detect the index numbers of liver and spleen respectively, detect content of TNF-a in blood and in spleen respectively.

先用硫酸链霉素给正常小鼠灌胃2d，出现菌群失调症状，再用STM灌胃造成小鼠STM感染，使用两岐双岐杆菌液干预治疗STM感染小鼠，检测不同治疗时间各组小鼠粪便STM菌落数、肝脾指数、血及脾中TNF-a的含量。采用SPSS12.0统计软件包进行数据处理分析，统计学方法采用双因素重复测量资料的方差分析、单因素随机化设计的方差分析、卡方检验、多组均数比较的非参数秩和检验。结果：随着治疗天数的增加，STM菌落数逐渐减少，未干预组、生理盐水组及双歧杆菌组比较结果均为P＜0.01；组间比较，双歧杆菌组STM数下降最快。

And unrooted trees were established. The accession numbers in GenBank of the sequences of 16S rDNA of the strains were followed by PFK1(DQ295034), PFK2(DQ295035), PFK3(DQ295036), LZCL(DQ295040), ZCS1(DQ295037), MMA1(DQ295041), MMA2(DQ295038), JSQ1(DQ295042), JSQ2(DQ295039), JSQ3(DQ295043). The Blast and phylogenetic tree analysis showed that
