| description | Bovine enterovirus (BEV) infection is one of the important infectious diseases that cause digestive and respiratory symptoms in cattle, posing a significant threat to the cattle industry. Currently, no vaccines or therapeutic drugs are available for this disease. In our study, we utilized a mouse model to investigate the effects of BEV infection on the gut microbiota and examine the therapeutic potential of magnolol (Mag), a polyphenolic bioactive substance, in terms of BEV infection. BEV infection significantly altered the microbiota composition, where the abundance of some beneficial bacteria, such as <i>Lactobacillaceae</i> and <i>Lactobacillus</i>, was markedly reduced. Mag effectively inhibited BEV infection in vivo. Upon BEV infection, Mag treatment reduced the α-diversity of the microbiota, with statistically significant differences on day 3 post-infection compared to the Mag-untreated group. More interestingly, Mag treatment significantly reversed the effect of BEV infection on the <i>Lactobacillaceae</i> and <i>Lactobacillus</i> abundance, indicating that Mag positively regulates beneficial bacteria. The fecal microbiota transplantation (FMT) experiment demonstrated that feces from Mag-treated mice significantly decreased the virus loads in the small intestine samples of BEV-infected mice. These findings demonstrate the interaction between BEV infection and the gut microbiota and highlight the important regulatory role of the gut microbiota in Mag’s anti-BEV effects, opening up a new avenue for preventing and controlling BEV infection via targeted modulation of the gut microbiota. |
