Can chronic stress be a causative factor that brings on IBS? And, at the same time, does IBS cause anxiety and depression?
Can certain probiotic dosing help ameliorate both conditions?
Three important questions that Ait-Belgnaoui et al. (2014) asked in their research, “Probiotic gut effect prevents the chronic psychological stress-induced brain activity abnormality in mice.”
The researchers make a strong claim that their study demonstrates a connection between certain probiotics supplementation and the reduction of markers of stress, anxiety, and IBS. Stress affects the gut, and the gut affects the brain, and vice versa: it is bi-directional.
Their claim is that Lactobacillus helveticus and Bifidobacterium longum given orally can help ameliorate chronic stress-induced abnormal brain plasticity, reduction in neurogenes, and increase in stress hormone.
Their findings highlight the important role of bacteria in the bi-directional communication of the gut-brain axis and suggest that probiotic treament may prove to be a useful therapeutic alternative in stress-related disorders such as anxiety and depression.

The Last Quiz Answer:
This is the wild ass (Equus africanus). It is believed to be the ancestor of the domestic donkey. They live in the desert area of the Horn of Africa (Ethiopia, Eritrea, Somalia). They can run almost as fast as a horse (around 45mph). They are a hardy animal and well adapted to desert life. They can sustain water loss of up to 30% of their body weight, and can drink enough water in two to five minutes to restore fluid loss. About 570 exist in the wild.
