Results of the experimental trials showed that mortalities were induced after injection of filtered tissue homogenates prepared from naturally OsHV-1 infected spat collected on French coasts during mortality outbreaks in 2008, suggesting that oyster spat mortalities require the presence of a UV sensitive agent.

The variations of immunological parameters, except for the PO activity, seem to be consistent with the in vivoresponse against the pathogenic Vibrio in shrimp exposed to severe hypoxia.

It is shown that penaeidin mRNA and protein are restricted to granular haemocytes and that their expression and distribution are regulated through dramatic changes in haemocyte populations, both circulating and infiltrating shrimp tissues.

DNA extracted by the Chelex method could be used to detect fewer than 20 cultured Vibrio cells in sea-water or shrimp hemolymph by this assay, and appears to be a reliable screening method for detecting V. penaeicida in shrimp and from the aquatic environment.

Metalloprotease Vsm Is the Major Determinant of Toxicity for Extracellular Products of Vibrio splendidus

Investigation of virulence factors in the oyster pathogen Vibrio splendidus LGP32 shows that toxicity is correlated to the presence of a metalloprotease and its corresponding vsm gene, and demonstrates that Vsm is the major toxicity factor in the ECPs of V. splendidus.

This study provides the first information describing the complex biofloc microbial community, which can help to understand the environment-microbiota-host relationship in this rearing system.

A high level of concordant results between azocaseinase activities and virulence of strains was obtained in this study and this phenotypic test could be useful for the evaluation of virulence in bacterial strains associated with mortality episodes.

It is shown that the ability of the shrimps to circumvent shrimp infections is closely related to a recovery phase based on the hematopoietic process.
