采用酶联免疫吸附试验（ELISA）研究了来自埃及一个养殖场的尼罗罗非鱼（Oreochromis niloticus）不同器官中微囊藻毒素（MCYSTs）的含量。MCYSTs在各器官中的分布差异显著。肠中的MCYST水平最高（821纳克/克鲜重），其次是肝脏（531.8纳克/克）和肾脏（400纳克/克）。在肌肉中检测到少量MCYST（102纳克/克）。本研究表明，养鱼场应监测有毒蓝藻水华的存在，以尽量减少鱼类暴露于强效肝毒素。(C)2003 Wiley Periodicals，Inc.
Microcystins (MCYSTs) that accumulated in different organs of the freshwater fish Oreochromis niloticus, collected from a fish farm in Egypt containing heavy blooms of Microcystis aeruginosa, were investigated using an enzyme-linked immunosorbent assay (ELISA). The distribution of MCYSTs in the organs varied significantly. The highest MCYST level was recorded in the guts (821 ng/g fresh weight), followed by the livers (531.8 ng/g) and kidneys (400 ng/g). Smaller amounts of MCYST were detected in muscles (102 ng/g). The present study suggests that fish farms should be monitored for the presence of toxic cyanobacterial blooms to minimize the exposure of fish to potent hepatotoxins. (C) 2003 Wiley Periodicals, Inc.
