Abstract:

In this study,Bacillus subtilis was selected to investigate its effect on the β-defensin expression of ovine ruminal epithelial cells cultured in vitro.Firstly,the ovine ruminal epithelial cells were cultured in vitro,then the epithelial cells were stimulated by Bacillus subtilis with different concentrations at different times,the expression of SBD-1 mRNA was determined by real-time fluorescence quantitative PCR(RT-PCR).The results indicated that the expression peak of SBD-1 mRNA was after 8 h treated by Bacillus subtilis with 1010 cfu•mL-1.The expression of SBD-1 was increased significantly after treated by Bacillus subtilis with different concentrations,and the expression at 109,1010,1011 cfu•mL-1 showed stronger induction response than the blank(P<0.01).This study reveals that Bacillus subtilis can induce the expression of SBD-1 in ovine ruminal epithelial cells.
