Egg Yolk IgY Production Using Booster Immunization Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IgY antibodies extracted from chicken eggs are underutilized for treating various diseases caused by pathogens despite being inexpensive and relatively easy to produce, necessitating a need for more effective and widespread use of these antibodies.
Innovation Solution
A method involving multiple exposures to antigens, regular antibody testing, and a high-nutrient diet for chickens to increase IgY production, followed by collecting eggs with enhanced IgY levels, which can be administered orally to enhance immune response against pathogens such as avian infectious bronchitis virus (IBV) and SARS-CoV-2.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If chickens are immunized with antigen to produce IgY antibodies in eggs, then antibody production is achieved, but the IgY levels naturally decline over time requiring continuous immunization
Solution Approach 1:
The patent implements periodic immunization schedules where chickens receive booster shots at predetermined intervals (e.g., every 4-6 weeks) to maintain IgY antibody levels in eggs. This periodic action counteracts the natural decline in antibody production over time, ensuring continuous supply of high-IgY eggs without requiring constant immunization.
Solution Approach 2:
The patent employs feedback mechanisms by regularly testing egg samples for IgY antibody concentrations and using this information to determine when booster immunizations are needed. This feedback loop allows optimization of immunization timing based on actual antibody levels, maintaining high IgY production efficiently.
2Quantity of substance
If multiple immunizations are administered to maintain high IgY levels, then antibody quantity increases, but the complexity of the production process increases
Solution Approach 1:
The patent implements self-service monitoring where farm staff regularly collect egg samples and test for IgY levels themselves, rather than relying on external laboratories. This self-testing approach simplifies management of the immunization program by providing immediate feedback on antibody levels, enabling timely booster decisions without complex external coordination.
Solution Approach 2:
The patent establishes predetermined immunization schedules with scheduled booster shots at specific time intervals (e.g., every 4-6 weeks). This preliminary planning simplifies management by removing the need for complex real-time decisions, as the immunization timeline is established in advance based on expected antibody decline patterns.
3Duration of action of stationary object
If antigen exposure frequency is increased to maintain antibody levels, then IgY production is sustained, but the cost and complexity of production increase
Solution Approach 1:
The patent optimizes immunization parameters by determining the optimal interval between booster shots (e.g., 4-6 weeks) based on antibody decline curves. This parameter optimization balances the need for sustained IgY production with the desire to minimize immunization frequency, simplifying the production process while maintaining effective antibody levels.
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 IgY-boost eggs contain 20% more antibodies than commercial eggs, effectively neutralizing SARS-CoV-2 at nanomolar concentrations and providing broad-spectrum protection against gastrointestinal and respiratory diseases, with potential therapeutic applications for SARS-CoV-2 prevention and treatment.
Implementation Method 1
When chicks are immunized, they produce antibodies that are detectable in their blood and in eggs that the chicks lay later on. Chickens that are immunized with an antigen will typically continue to lay eggs that contain the antibodies for the rest of their lives.
Implementation Method 2
A bird is exposed to one or more antigens. The exposing is performed on at least two separate occasions. A time between the at least two separate occurrences is at least one week.
Implementation Method 3
The egg may be prepared by purifying IgY from yolk of the egg
