Lactobacillus acidophilus DDS�-1(DDS-1), a gram-positive, non-spore forming homo-fermentive, catalagenegative rod, is an inhabitant of the human intestinal tract. For more than two decades, DDS�-1 strain has been marketed commercially worldwide as an effective probiotic strain. It has been the subject of a variety of in vitro , human, animal studies for more than 40 years. The focus of the efficacy research on this strain has been on its nutritional, antibacterial and anti-pathogenic, anti-carcinogenic and technological properties. Studies confirm that DDS-1 is acid and bile resistant and has the ability to colonize in the digestive track. Several studies have demonstrated the diverse beneficial effects of DDS�-1 validating its use as a broad-spectrum probiotic. These studies show DDS�-1 produces an antibacterial compound called acidophillin that demonstrates activities against pathogenic bacteria. DDS�-1 protects human epithelial cell lines from invasion by enteroinvasive Escherichia coli . DDS-1 was demonstrated to be effective in controlling atopic dermatitis in preschool children and reducing incidence of cold and flu. Other studies show DDS-1 can increase phagocytic and lymphocytic activity in mice, modulates the immune system. Other studies have demonstrated that DDS-1 has the ability to produce enzymes such as protease and lipase, improve digestion and boost immune function. DDS-1 has demonstrated reduction of IBS symptoms, and cholesterol lowering effect in a rat model. With the incorporation of a patented technology into manufacturing of DDS-1, it is stable for up to two years at ambient temperature (23 �C).
