Abstract: A method of treatment of pathogenic skin infectious disease using an effective antimicrobial amount of a composition of combined microorganisms comprising Bacillus stearothermophillus and Bacillus subtilis that can natural compete with pathogenic bacteria on the skin. This combination of microorganisms will utilize all limited resources that are available when there is an open wound and compete directly with pathogenic bacteria that can cause infection. Because of insufficient nutrition, the pathogenic bacteria on the skin cannot grow and therefore cannot cause infection, fungus, and other dermatology diseases that require skin nutrition to grow.
