Phenoloxidase 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 کاملSpore ornamentation of Minchinia occulta n. sp. (Haplosporidia) in rock oysters Saccostrea cuccullata (Born, 1778).
A Minchinia sp. (Haplosporidia: Haplosporidiidae) parasite was identified infecting rock oysters and morphologically described by Hine and Thorne (2002) using light microscopy and transmission electron microscopy (TEM). The parasite was associated with up to 80% mortality in the host species and it is suspected that the parasite would be a major impediment to the development of a tropical rock ...
متن کاملThe 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 کاملRelations between variable rates of growth, metabolic costs and growth efficiencies in individual Sydney rock oysters (Saccostrea commercialis).
Rock oysters from a mass selection trial were compared with wild-caught (control) oysters of the same age to determine the physiological basis for faster growth rates amongst the selected individuals, and to describe the associated flexibility in phenotypic traits of feeding, metabolism and growth. In confirmation of earlier studies, fast growth was associated with faster rates of feeding, redu...
متن کاملBiomonitoring of Exposure to Organophosphate Pesticides in New York City
Although urinary excretion levels of dialkyl phosphates (DAPs)—which are metabo lites and environmental degradates of OP insecticides—are useful as quantitative indi cators of exposure to OPs in agricultural workers, they are not as useful for the gen eral population. For agricultural workers, the source of the OP and time of exposure are typically known, and there is substan tial exposure...
