parasites and pathologic conditions of the cockle cerastoderma edule populations of the coast of galicia (nw spain). | a survey of pathological conditions affecting cockle populations of the most economically important natural beds of galician estuaries in nw spain was performed. samples of 30 adult cockles were collected from each of 34 natural beds in the spring of 1999 and processed by histological techniques. disseminated neoplasia were seen in samples from most of the natural beds, in some cases with a high prevalence. the gregarine nematopsis sp., larval trematode stages, and branchial extracellular large ... | 2001 | 11812111 |
virus-like particles associated with large foci of heavy hemocytic infiltration in cockles cerastoderma edule from galicia (nw spain). | | 2003 | 14726246 |
disseminated neoplasia and large foci indicating heavy haemocytic infiltration in cockles cerastoderma edule from galicia (nw spain). | a histopathological survey was performed to search for the cause of high mortality in the cockle cerastoderma edule in northern rias of galicia (northwestern spain). from limited sampling, 2 severe pathological conditions with high prevalence were found: disseminated neoplasia and the occurrence of numerous, large foci of heavy haemocytic infiltration. both conditions were detected in areas affected by high mortality and were absent (foci of haemocytic infiltration) or with lower prevalence (dis ... | 2001 | 11710555 |
genotyping of hepatitis a virus detected in bivalve shellfish in galicia (nw spain). | hepatitis a virus (hav) represents a significant public health problem due to its high persistence in the environment and its transmission through contaminated water and food. bivalve shellfish are filter feeders that can bioaccumulate human pathogens found in contaminated waters, their consumption being a potential cause of hepatitis a outbreaks. in this work, cultured and wild bivalve shellfish from the ría de vigo (galicia, nw spain) were analysed for the presence and genotyping of hav. a tot ... | 2010 | 20057087 |
distribution of aliphatic compounds in bivalve mollusks from galicia after the prestige oil spill: spatial and temporal trends. | the content and distribution of n-alkane (c8-c35) and isoprenoid (pristane and phytane) hydrocarbons were investigated in two species of bivalve mollusk, mussel (mytilus galloprovincialis) and cockle (cerastoderma edule), collected at different points of the galicia littoral zone during the period from december 2002 to february 2003 (after the prestige oil spill). samples were analyzed by high-resolution gas chromatography equipped with a flame ionization detector. the highest levels were found ... | 2006 | 16253223 |
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 |
evidence of retroviral etiology for disseminated neoplasia in cockles (cerastoderma edule). | epizootiologic outbreaks of disseminated neoplasia have been reported in association with massive mortalities of various bivalve species. in cockles, cerastoderma edule, this pathological condition was described in ireland and france. since 1997, different populations affected by this pathology have been detected in galicia (nw spain). transmission electron microscopy allowed the visualization of virus-like particles in neoplastic cells, resembling a retrovirus-like agent. to confirm this hypoth ... | 2007 | 17092515 |
interspecific variation of metal concentrations in three bivalve mollusks from galicia. | there has been growing concern about the inflow of metals to the coastal areas because they can be toxic to aquatic and human life. some studies have demonstrated the existence of species-specific differences in the metal concentrations of mollusks. we compared metal concentrations between mytilus galloprovincialis, used as a water quality indicator, and two other bivalve species collected for human consumption (venerupis pullastra and cerastoderma edule) in different locations on the galician c ... | 2004 | 15386128 |
