Solution Overview

Problem

Current treatments for wound infections and skin diseases caused by Staphylococcus aureus and Pseudomonas aeruginosa, such as chronic wounds, are often ineffective due to the bacteria's ability to form biofilms, leading to prolonged healing times and increased resistance to antibiotics, particularly in immunocompromised patients.

Innovation Solution

The use of specific lactic acid bacteria strains from the DSM collection, or their derivatives, which can coaggregate with Staphylococcus aureus and Pseudomonas aeruginosa, reducing their local concentration, inhibiting growth, and preventing biofilm formation, offering a non-antibiotic alternative for treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If antibiotic therapy is used to treat wound infections caused by Staphylococcus aureus and Pseudomonas aeruginosa, then bacterial growth is inhibited, but antibiotic resistance develops and treatment effectiveness decreases

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidantibiotic resistance
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent employs lactic acid bacteria as intermediary organisms that naturally coaggregate with pathogenic bacteria (Staphylococcus aureus and Pseudomonas aeruginosa). These probiotic bacteria bind to the pathogenic bacteria through cell surface interactions, forming aggregates that prevent the pathogens from adhering to wound tissue and forming biofilms. This intermediary approach eliminates the need for direct antibiotic application, thereby avoiding resistance development while maintaining treatment effectiveness.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If lactic acid bacteria are used to coaggregate with pathogenic bacteria, then bacterial load is reduced and biofilm formation is prevented, but the mechanism of action requires further clarification

Engineering Contradiction:
Improveanti-pathogenic effectVSAvoidmechanism understanding
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The lactic acid bacteria possess inherent coaggregation capabilities through their cell surface structures, allowing them to naturally bind to pathogenic bacteria without requiring external agents or complex activation processes. The bacteria perform their anti-pathogenic function autonomously through this self-service mechanism, where their natural biological properties enable them to reduce bacterial load and prevent biofilm formation in wound environments.

Inventive Principle:
Principle #25Self-service
