| a revised description of haplosporidium armoricanum, parasite of ostrea edulis l. from galicia, northwestern spain, with special reference to the spore-wall filaments. | haplosporidian spores from ostrea edulis, previously described as minchinia armoricana, were reexamined by light and electron microscopy. these spores were either free among host cells or enclosed in sporocysts. they contained two long epispore cytoplasm extensions (ece), each possessing cytoskeletal structures corresponding to the filaments. after lysis and degradation of the ece, these extensions disappeared and the spores became devoid of membrane-bound extensions. however, 2 long filaments ( ... | 1999 | 10599920 |
| detection of cryptosporidium oocysts in bivalve molluscs destined for human consumption. | clams (dosinia exoleta, ruditapes philippinarum, venerupis pullastra, venerupis rhomboideus, venus verrucosa), mussels (mytilus galloprovincialis), and oysters (ostrea edulis) were tested for the presence of cryptosporidium sp. oocysts using various stain techniques and a commercially available kit containing fluorescein isothiocyanate-conjugated monoclonal antibodies. all molluscs were harvested in northwest spain (galicia) except for r. philippinarum, which was from italy, and 1 of the 6 oyste ... | 2000 | 10958471 |
| herpesvirus infection in european flat oysters ostrea edulis obtained from brood stocks of various geographic origins and grown in galicia (nw spain). | we evaluated differences in productive traits and disease susceptibility among ostrea edulis stocks. we produced 4 to 5 families from each of 4 oyster populations (irish, greek and 2 galician) in a hatchery. spat corresponding to 19 different families were transferred to a raft in the ría de arousa (galicia, spain) for grow-out. samples of each family were histologically processed every month for 2 yr. one of the pathological conditions disclosed by histological examination was characterised by ... | 2008 | 18380216 |
| branchial lesions associated with abundant apoptotic cells in oysters ostrea edulis of galicia (nw spain). | an experiment to evaluate differences in growth, mortality and disease susceptibility among ostrea edulis stocks was performed. five families were produced from each of 4 oyster populations (irish, greek and 2 galician). the spat were transferred to a raft in the ria de arousa (galicia, spain) for grow-out. monthly samples of each family were histologically processed from 2001 to 2003. one of the pathological conditions discovered by this study was the occurrence of extensive branchial lesions c ... | 2006 | 16875400 |
| proteomic approach to probe for larval proteins of the mussel mytilus galloprovincialis. | a proteomic approach was used to search for larval proteins specific to the mussel mytilus galloprovincialis from galicia in northwest spain. the study included both a comparative analysis, through two-dimensional electrophoresis, of protein expression maps of the larvae of the mussel and of 5 abundant and commercially important bivalve species from the region (ostrea edulis, cerastoderma edule, pecten maximus, tapes decussatus, and venarupis pullastra) and subsequent mass spectrometric analysis ... | 2005 | 15976943 |
