The antidepressant-like effect of probiotics and their faecal abundance may be modulated by the cohabiting gut microbiota in rats

The gut microbiota has emerged as an important contributor to the regulation of a range of physiological systems throughout the body, including the brain (Sampson and Mazmanian, 2015). Intriguingly, several studies have presented interactions between the residing microbes, brain development and function and behaviour related to psychiatric disease (Sampson and Mazmanian, 2015). On this background, Cryan& colleagues defined the term psychobiotics as neuroactive probiotics (PRO) that, when ingested in adequate amounts, produce a mental health benefit in patients (Dinan et al., 2013).
