Ecophysiology of Brown Ring Disease in the Manila clam Ruditapes philippinarum, experimental and modelling approaches
Brown Ring Disease (BRD) in the Manila clam, Ruditapes philippinarum, is a disease caused by the bacterium Vibrio tapetis. This pathology was first observed in Northern Brittany (France) in 1987. The pathogenic agent enters in the extrapallial cavity (i.e. the space between mantle and shell), disrupts the normal production of periostracal lamina and causes an anomalous deposition of periostracu...
متن کاملTranscriptional changes in Manila clam (Ruditapes philippinarum) in response to Brown Ring Disease.
Brown Ring Disease (BRD) is a bacterial infection affecting the economically-important clam Ruditapes philippinarum. The disease is caused by a bacterium, Vibrio tapetis, that colonizes the edge of the mantle, altering the biomineralization process and normal shell growth. Altered organic shell matrices accumulate on the inner face of the shell leading to the formation of the typical brown ring...
متن کاملImpact of Brown Ring Disease on the energy budget of the Manila clam Ruditapes philippinarum
Brown Ring Disease (BRD) is a bacterial disease caused by the pathogen, Vibrio tapetis. The disease induces formation of a brown deposit on inner shell of the Manila clam, Ruditapes philippinarum. Development of this disease is correlated with a decrease in the condition index of infected clams. Experiments were conduced in order to assess the effect of the development of BRD on two parameters ...
متن کاملDispersal, recurrence and settlement of Manila clam, Ruditapes philippinarum
The majority of the marine benthos is pelagic in their larval stage. The Manila clam Ruditapes philippinarum, is widely distributed on sandy tidal flats across Japan and a commercially important shellfish. The clam has a planktonic larval stage, which lasts 2 to 3 weeks after hatching. In this stage, the most clam larvae are able to disperse over wide areas with the currents and then settle on ...
متن کاملMineral phase in shell repair of Manila clam Venerupis philippinarum affected by brown ring disease.
The mineral phase of shell repair in the Manila clam Venerupis philippinarum affected by brown ring disease (BRD) was characterised at various scales and at various stages of shell repair by confocal Raman microspectrometry and scanning electron microscopy. Spherulitic and quadrangular aragonite microstructures associated with polyene pigments were clearly observed. Von Kossa staining showed th...
