ABO-Matched Probiotic Bacteria for Gastrointestinal Colonization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current probiotic supplements are ineffective in promoting desired health effects for every individual due to a lack of personalization, as they do not account for variations in ABO blood group-specific bacterial adhesion and resistance to gastrointestinal conditions.
Innovation Solution
Development of probiotic bacteria strains with enhanced adhesion to ABO blood group antigens and improved resistance to acid and bile, characterized by specific adhesion and survival properties, allowing for personalized probiotic compositions and treatments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional probiotic supplements are used, then they are available for general use, but they are ineffective in promoting desired health effects for every individual due to lack of personalization
Solution Approach 1:
The patent applies local quality by selecting bacterial strains with specific adhesion properties tailored to individual ABO blood group types. Different strains are matched to specific blood group antigens (A, B, or O) to create personalized probiotic compositions that optimize colonization and health effects for each individual's biological characteristics
Solution Approach 2:
The patent utilizes parameter changes by measuring and comparing adhesion properties of bacterial strains against specific ABO blood group antigens. Strains are selected based on quantitative adhesion data and resistance parameters to acid and bile, creating personalized formulations adjusted to individual biological parameters
2Ease of manufacture
If probiotic bacteria are selected without ABO blood group consideration, then selection is simplified, but adhesion to mucosa and colonization efficiency are reduced
Solution Approach 1:
The patent employs parameter changes by using ABO blood group typing as a selection criterion for bacterial strains. The process involves determining an individual's blood group type and selecting strains with demonstrated adhesion to the corresponding blood group antigen, thereby optimizing colonization density through biologically relevant parameter matching
3Reliability
If bacteria with enhanced ABO antigen adhesion are selected, then colonization and pathogen blocking are improved, but the complexity of strain selection and personalization increases
Solution Approach 1:
The patent applies local quality by matching specific bacterial strains to specific ABO blood group types (A, B, or O) based on demonstrated adhesion properties. This creates targeted probiotic compositions that optimize colonization stability for each individual's blood group, rather than using a one-size-fits-all approach
Solution Approach 2:
The patent incorporates feedback mechanisms through adhesion assays that measure bacterial binding to ABO antigens. This quantitative feedback data is used to select and optimize strains for personalized compositions, ensuring reliable colonization while providing a systematic approach to managing complexity
4Ease of manufacture
If probiotics are formulated without considering acid and bile resistance, then formulation is simpler, but survival in gastrointestinal tract is reduced
Solution Approach 1:
The patent utilizes parameter changes by assessing and selecting bacterial strains based on their resistance parameters to acid and bile. These resistance characteristics are measured and used as selection criteria to ensure probiotic strains can survive the harsh gastrointestinal environment, thereby improving reliability without significantly complicating the formulation process
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 enhanced adhesion and survival properties of these strains improve colonization in the gastrointestinal tract, blocking pathogenic adhesion and providing longer-lasting health benefits, thereby effectively preventing and treating gastrointestinal disorders.
Implementation Method 1
certain bacterial strains showed enhanced in vitro adhesion to one or more of the ABO blood group antigens
Implementation Method 2
These properties may be helpful to enable the bacterium or metabolite thereof to survive the conditions of the stomach and gastrointestinal tract
Implementation Method 3
more than 40% average bile tolerance represented as growth in 0.9% dehydrated fresh bile
