Vibrio strains belonging to the Splendidus Clade have been repeatedly found in juvenile diseased oysters affected by summer mortalities. V. tasmaniensis LGP32 is an intracellular pathogen of oyster hemocytes which has been reported to alter the oxidative burst and inhibit phagosome maturation. We show here that LGP32 behaves as an intravacuolar pathogen that survives within large cytoplasmic vacuoles. LGP32 induces cytotoxic effects such as membrane disruptions and cytoplasmic disorders. Cytotoxicity was shown to be entirely dependent on LGP32 entry into hemocytes. Moreover, LGP32 releases outer membrane vesicles (OMVs) inside the phagosome. LGP32 OMVs were found to be protective against host defenses and to serve as vehicles for the delive...
