Sažetak
Yessotoxin (YTX) and its derivates are lipophylic disulphated polyeter algal toxins structurally related to ciguatoxins and brevetoxins. It was originally isolated from scallops Patinopecten yessoensis in Japan. Also, it has been found in shellfish from Norway, Chile, Italy, New Zealand and along the Russian coast of White Sea. YTX was also established as a causative agent of toxicity detected by mouse bioassay in the Northern Adriatic Sea. Its presence in the Northern Adriatic has been confirmed by liquid chromatography-mass spectrometry (LC-MS). The present study investigated the occurrence of YTX in the shellfish Mytillus galoprovincialis, collected in the summer of 2006, from July to October, from a localized site in Trogir Bay ; and from July to September from the Dubrovnik City Port. Analysis of shellfish toxicity was performed by LC-MS and enzyme-linked immunosorbent assay (ELISA). Analysis was supplemented by mousse bioassay. Along with shellfish toxicity, phytoplankton composition was investigated. The presence of YTX was established in several samples from Trogir and Dubrovnik. Phytoplankton analysis of sea water samples, collected in the investigated area, showed the occurrence of known YTX producers Protoceratium reticulatum, Lingulodinium polyedrum and Goniaulax spinifera.
