The prevention of this deadly disease is though administration of a vaccine, which until today has been at prohibitive cost making it unavailable for poor and underdeveloped nations, catalyzed by DBT, the Rotavac vaccine developed through public–private partnership is available at a fraction of the cost making it possible for universal access. Rotavirus is a double-stranded RNA virus. It belongs to Reoviridae family. The mode of transmission of this virus is fecal. The damage it causes to the neonates is the destruction of intestinal cell.

When sewage and organic wastes are broken down, inorganic nutrients enrich the water in the water body. The problem of excessive nutrient load in water bodies is called eutrophication. To know about pollution and eutrophication level of inland stagnant water bodies in India in my study I have taken the comparative study of two ponds of Bhagalpur . The names of the two ponds are Mukhra pond and Lalbagh pond respectively. In eutrophic water body constant decomposition of blooms, lead to oxygen depletion in water. Thus, in poorly oxygenated water with higher CO 2 level where
