Abstract
Probiotics are live microorganism that provide numerous health benefits without creating any hindrance to the immunity of the host organism. Probiotic bacteria’s in the gut have worked wonders and aided the immunity against virulent bacterial species. A similar effect could be expected in the environment where the probiotics can be used to reduce the S. Mutans species that is known to cause caries in the oral cavity. With this aim the efficacy of probiotic drink Yakult was tested by analysing the reduction in the colony counts of S. Mutans against normal curd by using Mitis salivarius bacitracin agar.
