Bacterial isolates were obtained from mortality events affecting Mytilus edulis and reported by professionals in 2010-2013 or from mussel microflora. Experimental infections allowed the selection of two isolates affiliated to V. splendidus/V. hemicentroti type strains: a virulent 10/068 1T1 (76,6% and 90% mortalities in 24h and 96h) and an innocuous 12/056 M24T1 (0% and 23,3% in 24h and 96h). These two strains were GFP-tagged and validated for their growth characteristics and virulence as genuine models for exposure. Then, host cellular immune responses to the microbial invaders were assessed. In the presence of the virulent strain, hemocyte motility was instantaneously enhanced but markedly slowed down after 2h exposure. By contrast, hemocyte velocity...
