Última Molecular and phenotypic characterization of Vibrio aestuarianus subsp francensis subsp nov., a pathogen of the oyster Crassostrea gigas ArchiMer Garnier, Matthieu; Labreuche, Yannick; Nicolas, Jean-louis. Eleven Vibrio isolates invading the hemolymph of live and moribund oysters (Crassostrea gigas) collected in the field and from a hatchery in France, were characterized by a polyphasic approach. Phylogenetic analysis of 16S rRNA, gyrB and toxR genes indicated high homogeneity between these strains and the Vibrio aestuarianus type strain (ATCC35048(T)), and confirmed previous 16S rRNA analysis. In contrast, DNA:DNA hybridization was from 61% to 100%, while phenotypic characters and virulence tests showed a large diversity between the strains. Nevertheless, several common characters allowed the isolates to be distinguished from the reference strain. On the basis of several distinct phenotypic characteristics, it is proposed to establish two subspecies within...

The oyster farming constitutes one of the major components of the global aquaculture. However, this sector is facing abnormal mortalities outbreaks that affect diploid and triploid oyster at their different life stages, in the hatcheries and in the field. During bivalve molluscs mortality events in France, bacteria initially classified into Harveyi group, were regularly isolated along with herpes virus, V. splendidus or V. aestuarianus. In order to fine tune the taxonomic affiliation of those isolates, a genotypic and phenotypic approach was used. The bacterial isolates, initially misclassified into the Harveyi clade, were shown to be genetically closed to V. tubiashii strains already recognized as the main causative agents of larvae and juvenile mollusc...
