Última Comparative studies on paralytic shellfish toxin profiles of marine snails, mussels and an Alexandrium tamarense isolate from the Mar del Plata coast (Argentina) OceanDocs Carreto, J.I.; El Busto, C.; Sancho, H.; Carignan, M.O.; Yasumoto, T.; Oshima, Y.. Toxin composition of three species of marine gastropods Zidona angulata, Adelomedon brasiliana and Pachycymbiola brasiliana and the mussel Mytilus edulis, and an Alexandrium tamarense isolate (AMI)from the Mar del Plata coast, were determined by means of a sensitive and specific HPLC technique. Cultures of A. tamarense contain N-sulfocarbamoyl derivatives as major toxins. The next most abundant components were GTX1 neoSTX and GTX4. As minor components, unusual decarbamoyl toxins were detected. Saxitoxin was the lowest of the 10 detectable toxins. Comparison of toxins profiles revealed significant differences between the toxic composition of the dinoflagellate and that accumulated in the tissues of their primary and secondary consumers. In the mussel M.... Tipo: Journal Contribution Palavras-chave: Marine molluscs; Toxicity; Toxicity; Http://aims.fao.org/aos/agrovoc/c_7826.

Caronetoids from caparace and internal organs of Artemesia longinaris were isolated and identified. The following carotenoid pigments were found in caparace: luteine, tunaxanthin diester, astaxanthin monoester and free astaxanthin. A much greater variety of pigments was isolated from internal organs: Ó- doradexanthin, a fucoxanthin derivate, chlorophylls degradation products and various xanthophylls in trace amounts. These pigments are of dietary origin. In the natural environment, A.longinaris takes preformed astaxanthin from the diet and transfers it to body tissues.

During november 1992 an intense bloom of the toxic dinoflagellate Alexandrium tamarense accurred in coastal waters from Mar del Plata, Argentina. Toxicity testing of Mytilus edulis populations of the region revealed high levels of paralytic shellfish poison. In order to study the possible PSP accumulation in mackerel (Scomber japonicus), mouse bioassay(AOAC) was performed in livers from individuals captured during December 1992. Liver extracts were lethal to mice; the sumptoms observed were typical of those caused by paralytic shellfish toxins. Although PSPS concentration is below the established limit for human consumption, it suggests that mackerel can accumulate PSP toxins from its food. On the basis of stomach content analysis of sampled mackerel and...
