Avian Antibody Composition with Colostrum Matrix for Oral ASF Protection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current vaccines for African Swine Fever (ASF) require extensive development to identify attenuated strains that do not cause illness, induce antibody production, and provide protection against multiple ASF isolates, posing a challenge due to genetic complexity and limited cross-reactivity of antibodies.

Innovation Solution

A composition using bovine colostrum as a protective matrix combined with specifically targeted avian-sourced antibodies and immune factors to provide broad-spectrum passive immunity against ASF virus isolates, leveraging controlled cross-reactivity and enhanced immune response.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional ASF vaccines are developed using attenuated strains, then protection against specific ASF isolates is achieved, but the vaccine development complexity and time increase significantly due to genetic complexity and limited cross-reactivity

Engineering Contradiction:

Improveprotection against ASF isolatesVSAvoidvaccine development complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses colostrum as an intermediary carrier to deliver antibodies and immune factors to swine. The colostrum matrix protects these biological agents during gastrointestinal passage and facilitates their absorption, enabling passive immunity transfer without requiring complex vaccine development processes

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs antibodies produced in avian species (chickens) as a copy mechanism. By immunizing chickens with ASF antigens and harvesting their eggs containing IgY antibodies, the system creates a scalable antibody production platform that avoids the complexity of developing attenuated viral strains in swine

Inventive Principle:

Principle #26Copying

2Reliability

If maternal antibodies are transferred via natural colostrum, then passive immunity is provided to neonates, but the quantity and specificity of antibodies are limited by the mother's recent exposure history

Engineering Contradiction:

Improvepassive immunity transferVSAvoidantibody quantity and specificity

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent changes the parameters of antibody production by using artificially immunized avian mothers instead of naturally exposed swine mothers. This allows control over the specificity and quantity of antibodies produced, as the avian mothers are deliberately immunized with specific ASF antigens before egg collection

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent makes the colostrum system universal by using avian colostrum (eggs) that can deliver antibodies against multiple ASF isolates. The egg-based delivery system serves multiple functions: protecting antibodies from degradation, facilitating absorption, and providing a scalable production method

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If antibodies are administered orally to swine, then passive immunity can be delivered through the gastrointestinal tract, but antibody effectiveness is reduced by gastric acid and digestive enzymes

Engineering Contradiction:

Improveoral administrationVSAvoidantibody effectiveness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent uses the egg yolk matrix as a protective shell or film that encases the antibodies. This matrix protects the antibodies from gastric acid and digestive enzymes during gastrointestinal passage, allowing them to reach the intestinal tract intact for absorption

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent creates a composite material system combining avian colostrum/egg yolk with antibodies and other immune factors. This composite provides a protective environment for the antibodies while maintaining their biological activity and facilitating their delivery to the intestinal tract

Inventive Principle:

Principle #40Composite materials

AI summary

A composition for treatment of African Swine Fever in swine includes avian-sourced antibodies specific for an African Swine Fever Virus isolate. These antibodies are produced by avian animals immunized against the African Swine Fever Virus isolate and mixed with a protective/reactive matrix obtained from, isolated from, or derived from, non-hyperimmune colostrum.
