Probiotic Skin Composition Inhibits Pathogenic Bacteria
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for skin infectious diseases, such as those caused by Mycobacterium tuberculosis and Staphylococcus aureus, face challenges including antibiotic resistance, side effects, and inefficacy in maintaining immune system balance, necessitating alternative antimicrobial approaches.
Innovation Solution
A topical composition combining Bacillus stearothermophillus and Bacillus subtilis microorganisms is used to compete with pathogenic bacteria, exhibiting synergistic microbicidal activity and inhibiting bacterial growth on skin and mucous membranes, thereby treating skin infections like acne, impetigo, and cellulitis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional antibiotics are used to treat skin infections, then bacterial growth is inhibited, but antibiotic resistance develops and side effects occur
Solution Approach 1:
Instead of using antibiotics to kill bacteria, the invention uses beneficial bacteria (probiotics) to compete with and suppress pathogenic bacteria through natural mechanisms such as resource competition, production of antimicrobial substances, and modulation of the host immune system. This inverted approach replaces chemical antimicrobials with biological agents that inherently avoid resistance development.
Solution Approach 2:
The probiotic bacteria serve as intermediaries between the host immune system and pathogenic bacteria. They modulate the immune system to enhance host defense responses while simultaneously competing with pathogens for resources and space, providing a dual mechanism that avoids direct use of harmful chemical agents.
2Reliability
If defensins are used as therapeutic antimicrobial agents, then broad spectrum antimicrobial activity is achieved, but chemical synthesis is challenging and recombinant production yields are insufficient
Solution Approach 1:
The probiotic bacteria in the composition naturally produce antimicrobial substances and modulate the immune system to produce defensins and other antimicrobial peptides at the site of infection. This eliminates the need for external synthesis and delivery of defensins, allowing the body's own cells to produce the needed antimicrobial agents when stimulated by the probiotic composition.
3Reliability
If macrophages are stimulated with cytokines to fight M. tuberculosis, then immune response is enhanced, but M. tuberculosis multiplies rapidly in macrophages
Solution Approach 1:
The probiotic composition is applied topically to the skin before systemic infection can establish itself. By colonizing the skin surface and mucous membranes with beneficial bacteria first, the composition prevents M. tuberculosis from establishing infection in macrophages in the first place, avoiding the problem of intracellular multiplication entirely.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively reduces skin infection symptoms and inflammation, demonstrating significant improvement in clinical studies with minimal side effects and no cumulative toxicity, making it a viable alternative to traditional antibiotics.

AI summary
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.
