Inhibitory effect of Bacillus coagulans TBC 169 strain on the pathogenic bacteria in intestinal tract

Objective To study the inhibitory effect of Bacillus coagulans(BC) TBC 169 strain on E.coli,Shigella dysenteriae,Salmonella typhi,Proteus vulgaris,Pseubomonas aeruginosa and Staphylococcus aureus which belong to pathogenic bacteria of intestinal tract.Methods The pathogenic bacteria were singly cultured first,respectively,and pH levels and viable bacteria amounts were determined at various time.Then BC was mixture cultured with other bacteria,respectiely,and pH levels and viable bacteria amounts were detemined again.The data obtained from the single and mixed culture were compared.Results BC TBC 169 strain had obvious inhibitory effect on the E.coli,Shigella dysenteriae,Salmonella typhi etc,peculiar,on the inhibitor effect of the Salmonella typhi and Pseubomonas aeruginosa was very good.Conclusion BC TBC 169 strain had obvious inhibitory effect on the pathogenic becteriae of intestinal tract.
