The role of phenoloxidase suppression in QX disease outbreaks among Sydney rock oysters (Saccostrea glomerata)
The paramyxean protozoan, Marteilia sydneyi, is the etiological agent of QX disease in Sydney rock oysters (Saccostrea glomerata). QX disease affects the farming of oysters in Queensland and on five rivers in New South Wales (NSW), Australia. Disease outbreaks occur during summer months (January to April) and are associated with high mortality rates (up to 98%), which limit the growing out peri...
متن کاملPhenoloxidase and QX disease resistance in Sydney rock oysters (Saccostrea glomerata).
QX is a fatal disease in Sydney rock oysters (Saccostrea glomerata) that results from infection by the protistan parasite, Marteilia sydneyi. Since 1997, the New South Wales Fisheries Service has bred S. glomerata for resistance to QX disease. The current study shows that the QX resistance breeding program has selected oysters with enhanced phenoloxidase (PO) activities. The third generation of...
متن کاملMolecular detection of Marteilia sydneyi, pathogen of Sydney rock oysters.
The life cycle of Marteilia sydneyi, the aetiological agent of QX disease in the Sydney rock oyster Saccostrea commercialis, is not known. We have developed and optimised 2 diagnostic assays, the polymerase chain reaction (PCR) and in situ hybridisation, for use in investigating the role of possible alternative hosts in the life cycle of this pathogen. PCR primers, designed within the ITS1 rDNA...
متن کاملBreeding for QX disease resistance negatively selects one form of the defensive enzyme, phenoloxidase, in Sydney rock oysters.
QX disease in Sydney rock oysters (Saccostrea glomerata) is caused by the paramyxean protozoan, Marteilia sydneyi. Disease outbreaks occur during summer (January to May) and can result in up to 95% mortality. The New South Wales Department of Primary Industries has been selectively breeding S. glomerata for resistance to QX disease since 1996. Previous work suggests that this breeding program h...
متن کاملThe effect of low salinity on phenoloxidase activity in the Sydney rock oyster, Saccostrea glomerata
This study tested the effects of low salinity on phenoloxidase activity in Sydney rock oysters (Saccostrea glomerata). Phenoloxidase is a key component of the immune system in S. glomerata. Previously, we have shown that decreased phenoloxidase activity is associated with susceptibility to fatal QX disease. In the current study, laboratory-based experiments were used to identify factors that co...
