Última Identification de marqueurs génétiques de la virulence chez Vibrio nigripulchritudo, un pathogène de crevettes pénéides en Nouvelle-Calédonie ArchiMer Reynaud, Yann. Since 1997, a new pathology seasonally occurs in new caledonian shrimp farms during the warm season and was named Summer Syndrome. Diseased Litopenaeus stylirostris shrimp suffer from a septicemic vibriosis which was attributed to V. nigripulchritudo. Preliminary studies based on a collection of V. nigripulchritudo strains have brought to light different virulence levels according to experimental infections results; three virulence statuses were defined: highly (HP), moderately (MP) and non pathogenic (NP). The aim of this work was to genetically characterize virulent V. nigripulchritudo strains. In a first step the genetic diversity of 58 V. nigripulchritudo strains was analyzed by MLST and AP-PCR, revealing a cluster of HP and MP strains, characterized...

Abalone aquaculture only recently developed in western Europe, but already it has to face numerous pathologies. Since 1998, the natural and farm stocks of Haliotis tuberculata suffer regularly high mortalities, mainly due to the pathogenic bacterium, Vibrio harveyi. The vibriosis of the European abalone, in particular its macroscopic signs, and the conditions necessary for its development have been studied in detail by field and laboratory experiments. We have been able to show the importance of the interplay between water temperature (>17°C), animal physiology (reproduction period) and a pathogenic strain (harbouring the plasmid pVCR1) for the development of this abalone disease. A limited localisation study of the abalone target tissues (gills, muscle...
