[nutritive value of shellfish consumed in chile].	the purpose of the present study was to determine the protein quality and digestibility of shellfish commonly consumed in chile, and to estimate its contribution to the protein needs of the chilean population. the shellfish studied were chorito (mytilus edulis chilensis), macha (mesodesma donacium), loco (concholepas concholepas), cholga (aulacomya ater), erizo (loxechinus albus) and almeja (no specific variety). the npu method was used to determine protein quality. the percentage of protein ade ...	1985	3834878
role and behaviour of the hydrophobic conditions in bacterial adhesion to incurrent siphon in a bivalve mollusc.	surface hydrophobicity is a widely distributed characteristic among human bacterial pathogens playing an important role in microbes retention by the incurrent siphon of a marine bivalve. feeding retention experiments with the bivalve mesodesma donacium was done with hydrophobic strains alone (staphylococcus aureus, salmonella paratyphi, vibrio cholerae) or with mixed cultures using a hydrophilic strain (aeromonas hydrophila). results showed that hydrophobic bacteria are retained in greater numbe ...	2000	10997493
competitive interactions in macroinfaunal animals of exposed sandy beaches.	the influence of biotic interactions in structuring macroinfaunal communities of exposed sandy beaches, an unstable habitat characterized by strong physical forces, is generally considered negligible. we investigated the hypothesis that competitive interactions during burrowing could potentially affect the intertidal distribution and abundance of macroinfaunal animals of sandy beaches using two species of invertebrates, a hippid crab, emerita analoga, and a bivalve, mesodesma donacium, common al ...	2004	15067539
first identification of azaspiracid and spirolides in mesodesma donacium and mulinia edulis from northern chile.	in an attempt to evaluate the risk for human consumption associated to the accumulation of lipophilic toxins by two commercially important bivalves: macha (mesodesma donacium) and clam (mulinia edulis) in coquimbo bay (chile), monitoring of these species was carried out from march to september 2008. the samples were analyzed by liquid chromatography-mass spectrometry (lc-ms) to detect okadaic acid, dinophysistoxins, pectenotoxins, azaspiracids, yessotoxins and spirolides. low levels of azaspirac ...	2010	19631679
molecular characterization of two kazal-type serine proteinase inhibitor genes in the surf clam mesodesma donacium exposed to vibrio anguillarum.	this study reports two kazal-type serine protease inhibitors (kpi) identified in a cdna library from the surf clam mesodesma donacium, and characterized through rapid amplification of cdna ends (race). the kpis, denoted as mdspi-1 and mdspi-2, presented full sequences of 1139 bp and 781 bp respectively. mdspi-1 had a 5'untranslated region (utr) of 175 bp, a 3'utr of 283 bp and an open reading frame (orf) of 681 pb that encodes for 227 amino acids. mdspi-2 showed a 5'utr of 70 bp, a 3'utr of 279 ...	2013	23528874
metazoan symbionts of the yellow clam, mesodesma donacium (bivalvia), in southern chile: geographical variations.	mesodesma donacium is a dominant species on sandy beaches along the chilean coast. however, the only previous parasite records for this species were obtained for the northern chilean coast (20° s-33° s), which dealt with cestodes, polychaetes, and copepods. in this study, the symbiotic fauna of m. donacium in its southern distributional range is reported, and the geographical variations in the occurrence of this fauna are evaluated. a total of 565 individuals of m. donacium were captured by loca ...	2014	25133890
use of cellulolytic marine bacteria for enzymatic pretreatment in microalgal biogas production.	in this study, we designed and evaluated a microalgal pretreatment method using cellulolytic bacteria that naturally degrades microalgae in their native habitat. bacterial strains were isolated from each of two mollusk species in a medium containing 1% carboxymethyl cellulose agar. we selected nine bacterial strains that had endoglucanase activity: five strains from mytilus chilensis, a chilean mussel, and four strains from mesodesma donacium, a clam found in the southern pacific. these strains ...	2014	24795376
identification and expression of antioxidant and immune defense genes in the surf clam mesodesma donacium challenged with vibrio anguillarum.	the immune system in marine invertebrates is mediated through cellular and humoral components, which act together to address the action of potential pathogenic microorganisms. in bivalve mollusks biomolecules implicated in oxidative stress and recognition of pathogens have been involved in the innate immune response. to better understand the molecular basis of the immune response of surf clam mesodesma donacium, qpcr approaches were used to identify genes related to its immune response against v ...	2015	25481276
