An antimicrobial-family name is not disease resistance
The evidence library is allowed to change in public. This page preserves the revised boundary, why it moved and which guides were affected.
What changed
The health guide now includes the 2025 NdCrus1 study while separating recombinant-protein protease and chitin assays from direct bacterial inhibition and outcomes in living shrimp.
Why it changed
The recombinant protein did not significantly inhibit either tested bacterium. It inhibited selected protease preparations and bound chitin materials in vitro, but the study included no living-shrimp bacterial challenge, gene manipulation, survival, pathogen-load, clearance or protection endpoint.

Affected practical guides
A public change is not automatically a retraction. A source may be added, a scope narrowed, a gap refined or an error corrected. The current guide and registry record own the current wording.
