Dear Sir,

We would like to highlight recent information on the previous report on “Novel insight on probiotic Bacillus subtilis: Mechanism of action and clinical applications.”[1]B. subtilis spores act as probiotic by possible mechanisms as mentioned in previous report include antimicrobial effect by synthesis of antimicrobial substances, antidiarrheal effect, immunostimulatory effect, competitive exclusion of pathogens, prevention of intestinal inflammation, and normalization of intestinal flora. However, in previous article, exact antidiarrheal mechanism and clinical safety profile of B. subtilis was not mentioned. Recent evidences show that B. subtilis CU1 strain is capable of acting directly on diarrhea by inhibiting the cystic fibrosis transmembrane conductance regulator (CFTR) expression (transporters involved in the secretion of water) and inducing the Na +/H + exchanger 3 (NHE-3) expression (transporters involved in the absorption of water) in the colon and thereby regulates the fluidity of intestinal tract and exerts potent antidiarrheal action. Hence, B. subtilis CU1 probiotic strain can be used for treatment and or/prevention of diarrhea.[2] According to European Food Safety Authority Qualified Presumption of Safety approach and Joint Food and Agriculture Organization of the United Nations/WHO guidelines, B. subtilis CU1 is identified at the strain and species level, using combination of genomic testing techniques and through random amplified polymorphic DNA polymerase chain reaction and pulsed-field gel electrophoresis analyses, to be lacking transferable antimicrobial resistances and toxigenic activity. Safety evaluations, bothin vitro and clinical study, demonstrated that B. subtilis CU1 strain is a nonpathogenic and nontoxicogenic strain of B. subtilis; safe and well-tolerated in healthy controls at 2 × 109 spores/day for total study period of 4 months (for initial 10 days of every month repeatedly) without any undesirable physiological effects on markers of liver and kidney function, complete blood counts, hemodynamic parameters, and vital signs.[3] Hence, B. subtilis can be considered as a promising probiotic for managing various clinical conditions in humans with utmost safety profile.
