A new multiplex MALDI-TOF MS platform rapidly detects 13 goose viruses simultaneously. This advanced diagnostic tool improves waterfowl disease surveillance and management by identifying complex co-infections efficiently.
Area of Science:
- Veterinary Virology
- Infectious Disease Diagnostics
- Mass Spectrometry Applications
Background:
- Waterfowl farming suffers significant economic losses due to polymicrobial infections.
- Current diagnostic methods struggle with simultaneous detection of multiple pathogens, hindering effective disease management.
Purpose of the Study:
- To develop and validate a high-throughput multiplex MALDI-TOF MS platform for simultaneous detection of 13 goose-origin viruses.
- To overcome limitations of conventional single-pathogen diagnostics in complex infection scenarios.
Main Methods:
- Development of a multiplex MALDI-TOF MS assay targeting 16 conserved genomic signatures of 13 goose viruses.
- Analytical validation assessing limits of detection, specificity, and reproducibility.
- Clinical validation using 74 field specimens (swabs, tissues) and comparison with qPCR.
Main Results:
- The assay achieved high sensitivity (2.87-29 copies/μL) and specificity.
- Excellent reproducibility with CVs ≤ 3.3%.
- Clinical validation showed 98.3% concordance with qPCR, excelling in detecting co-infections.
Conclusions:
- The developed multiplex MALDI-TOF MS platform offers a rapid, high-throughput, and scalable solution for waterfowl disease diagnostics.
- This technology enables comprehensive pathogen profiling, aiding outbreak investigation, surveillance, and disease management.
