Lactic Acid Bacteria Reduce MRSA Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods are inadequate in preventing the transfer of antibiotic-resistant pathogens like MRSA between surfaces and subjects, leading to widespread infections and a significant financial burden on healthcare systems.
Innovation Solution
A composition comprising lactic acid bacteria is used to reduce the transfer of pathogenic microorganisms between surfaces, specifically including strains like Lactobacillus and Enterococcus, which are applied topically or as oral supplements to inhibit the colonization and transfer of MRSA.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cleaning and disinfection methods are used to prevent MRSA transfer, then infection control is maintained, but the methods are inadequate and do not effectively reduce pathogen transfer
Solution Approach 1:
The patent introduces lactic acid bacteria as an intermediary substance that mediates between the host and pathogenic microorganisms. These bacteria colonize the skin surface and actively inhibit MRSA transfer through competitive exclusion and antimicrobial mechanisms, providing superior protection compared to traditional disinfectants
Solution Approach 2:
The patent changes the biological parameter of the skin surface by introducing probiotic bacteria that alter the microbial ecosystem. This transforms the skin from a passive surface to an active defensive barrier, reducing pathogen transfer by up to 99% through microbial community modulation
2Reliability
If antibiotic treatment is used to treat MRSA infections, then infection is treated, but antibiotic resistance develops and treatment options are limited
Solution Approach 1:
The patent converts the harmful effect of antibiotic resistance into a benefit by using non-pathogenic lactic acid bacteria that inhibit MRSA through non-antibiotic mechanisms. This approach eliminates the selective pressure for resistance while maintaining effective infection control
Solution Approach 2:
The lactic acid bacteria provide self-service protection by colonizing the skin and maintaining a protective microbial ecosystem. The bacteria continuously inhibit pathogen transfer through their metabolic activities and competitive interactions, eliminating the need for external antibiotic intervention
3Object-affected harmful factors
If lactic acid bacteria are applied to reduce MRSA transfer, then pathogen transfer is decreased by up to 99%, but the mechanism involves complex microbial interactions
Solution Approach 1:
The patent segments the complex microbial interaction into distinct functional components: lactic acid bacteria colonization, competitive exclusion of MRSA, and antimicrobial substance production. This segmentation simplifies the understanding of how probiotics reduce pathogen transfer through multiple coordinated mechanisms
