The antagonistic activities against animal entero-pathogenic bacteria were investigated with 444 natural substances fermented by various probiotics. A white rice product fermented (FWR) by Clostridium butyricum IDCC 9207 with a high growth inhibition of Salmonella typhimurium KCTC 2054 and Escherichia coli O157:H7 was selected. Also, a FWR was shown to suppress 8 among 21 pathogenic bacteria. In a mouse model with salmonella (× 10∨9 CFU/mouse) infection, 5 samples (200 ㎕/mouse/day) were fed to mice (n = 25) for 18 days. A fermented white rice containing C. butyricum IDCC 9207 (FWRCb9207) among 5 samples significantly inhibited the growth of salmonella, while in the control group (PBS, tetracycline) the number of salmonella increased. And the treatment with FWRCb9207 was found to increase the secretory immunoglobulin A (sIgA) level in the feces of salmonella-infected mice. The results obtained in this study suggest that a FWRCb9207 might be utilized as a feed additive in pigs and poultry diets.
