L. plantarum Inducia is used for reducing the level of LDL-cholesterol in blood for preventing the cholesterol metabolism disorders and cardiovascular disorders. L. plantarum Inducia enhances simultaneously the natural defense potential and cellular immunity, and as anti-oxidative agent enhances anti-oxidative activity of human body by reducing the level of oxidized low density lipoprotein (ox-LDL). The strain is also used as an antimicrobial agent for lowering risk of Clostridium difficile associated diarrhoeae (CDAD) by preventing germination of C. difficile spores and by suppressing proliferation of its vegetative cells. The compositions comprising L. plantarum Inducia decrease the levels of LDL-cholesterol and ox-LDL in blood, enhance the natural defense potential and lower risk of CDAD. The composition may further comprise xylitol.
