Abstract: To explore the molecular mechanism of the effect of Bacillus cereus PAS38 on the immunity in broilers. 60 7-day-old broilers were divided into two groups,the control group was fed with basal diet,and the treatment group was fed with basal diet containing Bacillus cereus PAS38 1×106 cfu/g. Six broilers were randomly selected from each group at the age of 42 days,spleens were taken and total RNA was extracted,then,and reversed transcription to cDNA. SSH and ACSSH techniques were used to construct splenic differential gene library and screen immune-related genes respectively. The results showed that 119 differentially expressed genes were screened by SSH,including 63 up-regulated genes and 56 down-regulated genes,and including 9 immunoregulatory genes,while five differentially expressed genes were screened by ACSSH,all of which were down-regulated genes,and no immunoregulatory genes were found. The results indicated that feeding Bacillus cereus PAS38 could affect the expression of immune genes such as JCHAIN, FTH1 and P2RX7 in the spleen of broilers,SSH library was superior to ACSSH library,and ACSSH technology was defective.

Key words: Broilers, Bacillus cereus, SSH technology, ACSSH technology, Differential gene
