Abstract

Significance: Since 2009, an emergent shrimp disease, acute hepatopancreatic necrosis disease (AHPND), has been causing global losses to the shrimp farming industry. The causative agent of AHPND is a specific strain of Vibrio parahaemolyticus . We present evidence here that the opportunistic V. parahaemolyticus becomes highly virulent by acquiring a unique AHPND-associated plasmid. This virulence plasmid, which encodes a binary toxin [ V. parahaemolyticus Photorhabdus insect-related toxins (PirA vp and PirB vp )] that induces cell death, is stably inherited via a postsegregational killing system and disseminated by conjugative transfer. The cytotoxicity of the PirA vp /PirB vp system is analogous to the structurally similar insecticidal pore-forming Cry toxin. These findings will significantly increase our understanding of this emerging disease, which is essential for developing anti-AHPND measures.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
