“…Individual oysters expressed either one or two of these forms. Using a similar electrophoretic technique, Newton et al [21] identified just two types of phenoloxidase in wild type and third generation disease resistant (QXR 3 ) oysters. The native-PAGE protocol used in previous analyses was optimised in the current study by improving sample preparation and staining techniques.…”

“…Gels were electrophoresed in 0.03 M TriseHCl containing 0.187 M glycine (pH 8.3) for 3 h at 110 V (4 C). After electrophoresis, gels were stained for phenoloxidase enzyme activity with 20 mM hydroquinone (1,4-benzenediol; Sigma Aldrich, Sydney, NSW, Australia; 15 min) in FSW containing 5 mM 3-methyl-2-benzothiazolinone hydrazone (MBTH; Sigma Aldrich), before being rinsed with distilled water [21].…”

“…Our data indicate that breeding for QX resistance has affected the phenoloxidase system of oysters. Newton et al [21] found that third generation QX disease resistant (QXR 3 ) oysters had significantly higher phenoloxidase activities than the wild type population, and that QXR 3 and wild type oysters expressed different forms of phenoloxidase.…”

“…On the basis of these results, the authors suggested that increased disease resistance in the QXR 3 population was due to selection for different types of phenoloxidase [21]. However, the precise nature of this selection could not be resolved because of the small sample sizes tested and the limited resolution of the native-PAGE system used to identify different types of phenoloxidase.…”

“…Peters and Raftos (2003) correlated physiological immuno-suppression (a drop in levels of the protein phenyloxidase) to infection with M. sydneyi. In addition, Newton et al (2004) showed that oysters with a level of resistance to marteiliosis had higher phenyloxidase (PO) activity and they identified a novel form of PO which may contribute to enhanced immune defence in selected stock. These studies may lead to the provision of a genetic marker which can be used with confidence to secure commercially viable levels of resistance to marteiliosis.…”

-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.Key words: Taxonomy / Epidemiology / Pathology / Diagnosis / Paramyxean parasites Résumé -Marteiliose des mollusques : une synthèse. 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.
