| Le milieu marin côtier est constamment soumis à des apports polluants continentaux. Des agents pathogènes, parmi lesquels des virus entériques humains, présents dans ces rejets, contribuent à la contamination microbiologique du littoral. La survie des virus dans l'eau de mer est prolongée grâce à leur association aux matières organiques, aux particules en suspension et aux sédiments qui constituent un véritable réservoir de virus. Les fruits de mer, de par leur activité de nutrition par filtration, se comportent comme de véritables filtres à micro-organismes : en même temps qu'ils absorbent les éléments nécessaires à leur alimentation, ils retiennent et accumulent activement les virus libres ou associés à des supports particulaires. Ces données conduisent... |

| Shellfish consumption is clearly associated with the transmission of enteric viruses. The channel of transmission of enteric viruses to human beings could be decreased particularly if the systems of depuration of shellfish were optimized, standardized and if their viral efficiency was controlled. The purpose of this work was to study the contamination of oysters and to assess the efficiency of several depuration processes. Our study have demonstrated that in some cases, 50% of oysters samples contain enteric viruses or H.A.V. antigen and the quantities of viruses range from 17 to 246 FF for the rotaviruses and from 124 to 200 for the enteroviruses per 100 g of tissue. According to our results, the exclusive use of a bacteriological criterium to determine... |
