Abstract

paralytic shellfish toxin production by mouse bioassay.1) The organism was first described from a red tide in Alexandria Harbour, Egypt2) and a recent reinvestiga tion of material from this sammmmme locality3) has demonstrated the synonymity of Alexandrium Halim and Protogonyaulax Toylor,4) which includes paralytic shellfish toxin producing species of the so-called tamarensis group. However, the precise chemical composition of the toxin produced by this dinoflagel late is still unknown. In the present study, toxins in dinoflagellate as well as mussels contaminated by the organism were analyzed by a high preformance liquid chromatography (HPLC) method which has been specially developed for paralytic shellfish toxins.5)

澳洲甲藻亚历山德菌产生麻痹性贝类毒素
这种生物最初是在埃及亚历山大港的一次红潮中发现的,最近对该地区的材料进行的重新调查表明,Halim Alexandrium和Toylor Protogonyaulax是同源的,其中包括所谓的tamarensis组的麻痹性贝类毒素产生物种。然而,这种鞭毛藻产生的毒素的确切化学成分仍然是未知的。本研究采用专为麻痹性贝类毒素而开发的高效液相色谱(HPLC)方法,对受该生物污染的甲藻和贻贝中的毒素进行了分析。
