Multivalent Vaccine for Tenacibaculum and Moritella Infections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vaccines and diagnostic tools are inadequate for effectively preventing and diagnosing tenacibaculosis in farmed fish, as they do not account for the role of Tenacibaculum species in causing ulcers, leading to ongoing financial losses and ethical concerns in aquaculture.
Innovation Solution
A novel Tenacibaculum isolate is identified and characterized, which can induce tenacibaculosis in challenge studies, and specific nucleic acid sequences are provided for developing vaccines and diagnostic methods to detect Tenacibaculum infections, distinguishing them from Moritella viscosa infections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current vaccines targeting Moritella viscosa are used, then protection against winter ulcer is provided, but outbreaks of winter ulcer still occur because the vaccines do not account for Tenacibaculum species involvement
Solution Approach 1:
The patent develops a multivalent vaccine composition that combines antigens from both Moritella viscosa and Tenacibaculum species, enabling the vaccine to protect against multiple pathogens simultaneously. This resolves the contradiction by making the vaccine universally effective against different causative agents of ulcerative diseases while maintaining its protective function.
Solution Approach 2:
The vaccine composition is segmented into distinct antigen components from different bacterial species (Moritella viscosa and Tenacibaculum), allowing each pathogen-specific antigen to function independently. This segmentation enables the vaccine to address multiple pathogens without compromising the effectiveness against each individual pathogen.
2Measurement precision
If diagnostic tools are developed based on Moritella viscosa only, then detection of winter ulcer cases is enabled, but accurate differentiation from Tenacibaculum infections cannot be achieved
Solution Approach 1:
The diagnostic system uses segmented, pathogen-specific nucleic acid sequences and antibodies that target either Moritella viscosa or Tenacibaculum species specifically. This allows the diagnostic tool to accurately detect and differentiate between the two pathogens, resolving the contradiction by enabling precise measurement of each pathogen's presence independently.
Solution Approach 2:
The patent introduces pathogen-specific nucleic acid sequences and antibodies as intermediary markers that mediate between the sample and the detection system. These intermediaries provide specific binding to either Moritella viscosa or Tenacibaculum, enabling accurate differentiation and resolution of the diagnostic contradiction.
3Ease of manufacture
If continued use of single-pathogen vaccines is maintained, then manufacturing simplicity is preserved, but ongoing financial losses from ineffective vaccination occur
Solution Approach 1:
The patent merges multiple antigen components from different bacterial species into a single multivalent vaccine composition. This combining approach maintains manufacturing efficiency by producing one integrated vaccine product rather than multiple separate vaccines, while simultaneously improving effectiveness to prevent economic losses from vaccine failure.
Solution Approach 2:
The multivalent vaccine composition provides universal protection against multiple pathogens that cause ulcerative diseases. This multi-functionality resolves the contradiction by enabling a single vaccine product to address several pathogens, maintaining manufacturing simplicity while improving economic outcomes through effective disease prevention.
