Rotavirus infection is the most common diarrheal disease worldwide in children under five years of age, and it often results in death. In recent years, research on the relationship between rotavirus and probiotics has shown that probiotics are effective against diarrhea. A clinical trial has reported that Bifidobacterium longum BORI reduced diarrhea induced by rotavirus. The present work investigated the anti-rotaviral effect of B. longum BORI by cytopathic effect observation and real time cell analyses. Our study found that B. longum BORI showed strong anti-rotaviral effect when incubated with MA104 cells prior to viral infection, suggesting that the probiotic does in fact interfere with the interaction of viruses and host cells. It is believed that the efficacy is due to low-molecular weight and non-protein components derived from B. longum BORI. This discovery can help broaden the industrial application of B. longum BORI, which has been proven to be a safe and effective probiotic.
