Abstract:

Les populations de bivalves exploités subissent régulièrement des épizooties qui affaiblissent voire déciment les stocks, et qui peuvent avoir des conséquences majeures pour l'aquaculture. Ces maladies, dues à des virus, bactéries, ou parasites, se développent particulièrement au printemps et en été. Ces périodes de l'année offrent également des conditions propices aux efflorescences de micro-algues toxiques, dont des dinoflagellés du genre Alexandrium. Ainsi, le risque de co-occurrence d'efflorescences d'Alexandrium sp. et de maladies infectieuses chez les bivalves est élevé. Or, ces micro-algues synthétisent et excrètent des neurotoxines et des composés cytotoxiques responsables d'altérations physiologiques chez les bivalves. L'objectif de cette thèse est d'évaluer les effets combinés d'une exposition à Alexandrium sp. et d'une infection par des agents pathogènes sur la physiologie des bivalves, à travers l'étude de différentes interactions tripartites bivalve - pathogène - Alexandrium sp. Les résultats de ce travail indiquent que différents profils de réponse existent en fonction des espèces impliquées dans ces interactions. Ainsi, une exposition à Alexandrium sp. peut augmenter le taux d'infection par des agents pathogènes chez des bivalves ou au contraire le diminuer. Les réponses hémocytaires associées peuvent traduire l'implication des défenses immunitaires dans ces modulations hôte-pathogène. De plus, l'exposition à des agents pathogènes peut interférer avec le processus d'accumulation de toxines algales dans les tissus des bivalves, illustrant la complexité de ces interactions. Ces résultats, associés à l'observation de lésions tissulaires chez les bivalves peuvent traduire l'altération des activités de nutrition (filtration, digestion...). Ce travail de thèse apporte une meilleure compréhension de l'implication des efflorescences toxiques dans le développement des maladies touchant les bivalves d'intérêt commercial, mais également de l'implication de l'environnement biotique des bivalves sur l'accumulation de phycotoxines réglementées.

Bivalve populations undergo regular epidemics that weaken or decimate exploited stocks and thus limit aquaculture. These diseases are caused mainly by viruses, bacteria or parasites, and occur primarily during spring and summer. This period of the year also provides favorable conditions for toxic dinoflagellate blooms, including species of the genus Alexandrium. Thus, the risk of Alexandrium sp. blooms and infectious diseases co-occurring in bivalves is high. However, these micro-algae synthesize and excrete toxins and cytotoxic compounds responsible for physiological changes in bivalves and could lead to an immuno-compromised status.The objective of this thesis is to evaluate the combined effects on bivalve physiology of exposure to the toxic dinoflagellate, Alexandrium sp., and infection by pathogens, through the study of different bivalve - pathogen - Alexandrium sp. tripartite interactions. The results of this work highlight the species-specific nature of these impacts.Thus, exposure to Alexandrium catenella reduces the herpesviruses infection in oyster Crassostrea gigas, whereas the dinoflagellate A. fundyense increases the susceptibility of C. virginica oyster to the parasite Perkinsus marinus, probably via immuno-suppression, as suggested by the partial inhibition of hemocyte responses. Additionally, the effect of a toxic algal bloom on oyster susceptibility to opportunistic diseases when exposed to a new microbial environment (simulating a transfer) was evaluated. Hemocyte responses to a changing microbial environment were suppressed by exposure to A. catenella, although no new bacterial infection was detected.Finally, exposure to pathogens or to a new microbial environment interferes with the processes by which oysters exposed to A. catenella accumulate algal toxins, illustrating the complexity of these interactions. These results provide a better understanding of the involvement of toxic algal blooms in the development of diseases affecting commercial bivalve species, but also of the involvement of the bivalve biotic environment in the accumulation of regulated toxins.
