...Rather than a direct effect of the lactobacilli reducing faecal moisture content, it is probable that this effect resulted from the mitigation of B. pilosicoli colonization and infection, hence alleviating clinical symptoms including increased faecal moisture content (Jamshidi & Hampson, 2003)....
