Abstract
Among mollusc pathogens, paramyxeans are an important group of protistan parasites belonging to the genera Marteilia and Marteilioides. Marteilia refringens and M. sydneyi are of particular concern given their potential impact on mollusc aquaculture world-wide. Aber disease and QX disease are currently listed by the OIE, the World Organisation for Animal Health. After more than thirty years of existence in the scientific literature, these organisms still pose questions and research challenges to investigators. This paper reviews current knowledge of the group and key references. The review was focused on taxonomy, epidemiology, pathology and potential control methods for these organisms in order to enhance understanding of paramyxean infection issues in mollusc aquaculture.


Résumé
Au nombre des agents pathogènes des mollusques, les paramyxéens, notamment les agents appartenant aux genres Marteilia et Marteilioides, sont des protistes parasites des plus importants. Marteilia refringens et M. sydneyi constituent un souci majeur compte tenu de leur impact potentiel sur la conchyliculture dans le monde. La maladie des Abers et la maladie du Queensland (QX) sont actuellement répertoriées par l'Office International des Epizooties. Après plus de trente années d'existence dans la littérature scientifique, ces organismes posent encore questions et défis aux investigateurs. Cet article fait l'état des connaissances sur le sujet en s'attachant plus particulièrement à la taxonomie, l'épidémiologie, la pathologie et les méthodes potentielles de contrôle de ces organismes dans l'optique d'une meilleure compréhension de la problématique des paramyxéens en conchyliculture.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
