In the frame of MOREST project, a common biological material, resulting of a mixture of different families produced in experimental hatchery, was reared in two different environmental fields : Normandy and Charente. Concomitantly, a pool was conditioned at the Ifremer Argenton hatchery with three different algae levels : 4%, 8% and 12% of algal dry weight per oyster dry weight. During the experiments, five immune parameters were studied in parallel with survival rate and reproductive status (stages and intensity). Site location, seasonal variations and experimental diet level clearly influenced oyster immune parameters. Haemocyte counts were higher for oysters reared in Normandy than those reared in Charente and in hatchery. Granulocyte percentage was... |

Ralstonia solanacearum (Smith) Yabuuchi es el agente causal de la marchitez bacteriana. Esta enfermedad afecta a numerosos cultivos de importancia económica tales como: tomate, papa, tabaco, banana, berenjena y algunas plantas ornamentales, especialmente en las zonas tropicales y subtropicales. La amplia gama de hospedantes, su distribución y elevada variabilidad, hacen difícil el control de la enfermedad. En este trabajo se exponen los mecanismos de patogenicidad de esta bacteria, así como los mecanismos moleculares mediante los cuales se ejerce la resistencia natural e inducida en la planta. |
