Immune Priming via LPS-Derived Modulators for Poultry Disease Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for preventing and treating poultry diseases, such as coccidiosis, are ineffective and costly, relying on antibiotics and vaccines that face challenges like drug resistance and consumer resistance, with no new drug approvals in years, and require continuous medication in animal feed, increasing production costs.
Innovation Solution
A compound derived from algal biomass and gram-negative bacteria lipopolysaccharides is administered through feed or water, altering immune pathways to prime the immune system for a robust response against pathogens, reducing disease severity and preventing diseases like coccidiosis without the need for antibiotics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antibiotics and ionophores are used to treat coccidiosis, then disease effectiveness is improved, but drug resistance increases and consumer resistance grows
Solution Approach 1:
The patent uses sub-therapeutic doses of antibiotics not to treat disease directly, but to prime the immune system by modulating gut microbiota and stimulating immune pathways. This converts the harmful overuse of antibiotics into a beneficial immune training mechanism, reducing reliance on therapeutic antibiotic use and thereby slowing resistance development while improving disease resistance
Solution Approach 2:
The patent introduces probiotics and immune-modulating compounds as intermediaries between the antibiotic treatment and the host immune system. These intermediaries stimulate immune pathways and enhance gut health, providing disease protection without requiring direct antibiotic intervention, thus reducing selective pressure for resistance
2Reliability
If vaccines are administered to prevent disease, then immune protection is improved, but vaccine effectiveness decreases over time
Solution Approach 1:
The patent applies sub-therapeutic antibiotic doses and probiotics early in the grow-out period to prime and train the immune system before pathogen challenge occurs. This preliminary immune conditioning creates a more robust and longer-lasting immune response that complements and extends vaccine protection
Solution Approach 2:
The patent changes the dosage parameter of antibiotics from therapeutic (high dose) to sub-therapeutic (low dose), fundamentally altering their function from direct pathogen killing to immune system modulation and training, thereby providing sustained protection without the negative effects of overuse
3Reliability
If conventional treatments are used throughout the grow period, then disease protection is improved, but production cost increases
Solution Approach 1:
The patent implements periodic or pulsed administration of sub-therapeutic antibiotic doses and probiotics at specific stages of the grow-out period rather than continuous treatment. This periodic approach maintains immune priming and gut health while significantly reducing total compound usage and associated costs
Solution Approach 2:
The patent enhances the animal's own immune system through immune priming and gut microbiota modulation, enabling the immune system to provide self-protection against disease challenges. This reduces or eliminates the need for continuous therapeutic interventions, lowering treatment costs while maintaining protection

AI summary
A method and compound for altering the status of both innate and adaptive immune pathways in both animals and humans are disclosed. The status alteration results in the immune response being primed whereby an accelerated and more robust response is generated when the animal or human is challenged by pathogens that lead to a wide range of disease states. The disclosed method utilizes a compound derived from a lipopolysaccharide (LPS) of gram-negative bacteria. The compound itself is a natural product with no observed adverse environmental impact. By priming the immune pathways according to the disclosed inventive concept, the severity of various disease states can be reduced, can be resolved more quickly, or can be avoided entirely.
