甲藻属的多种物种产生贝类毒素（冈田酸和甲藻毒素，OA/DTXs类似物）和/或果胶毒素（PTX）。直到2008年，DSP事件（疾病和/或贝类捕捞关闭）才被认为是对美国人类健康的威胁。本研究对甲藻属5个种的20个菌株进行了鉴定。与经历过DSP事件的三个美国沿海地区隔离：东北/大西洋中部，墨西哥湾和太平洋西北部。使用形态测定和基于DNA的证据相结合，7个东北/大西洋中部分离株和4个太平洋西北分离株被归类为D。acuminata的分离物中，有4个菌株被鉴定为D. norvegica分离物中，有2个分离物被鉴定为D. fortii和3个分离自墨西哥湾的菌株被鉴定为D.卵和D.尾状体毒力测定结果表明，D. acuminataandD.在美国境内，因其地理来源而异。与其他三个种属的毒素谱不可能进行跨区域比较;然而，在每个区域内，D. fortii、黑腹拟步行虫D. ovum和D.观察尾状核。对来自各个州和部落监测项目的历史和最近数据进行了汇编和比较，包括最大记录的甲藻属细胞丰度，商业贝类中记录的OA/DTXs最大浓度和捕捞关闭的持续时间，以提供有关DSP对区域公共卫生和贝类产业的潜在影响的观点。
Multiple species of the genusDinophysisproduce diarrhetic shellfish toxins (okadaic acid andDinophysistoxins, OA/DTXs analogs) and/or pectenotoxins (PTXs). Only since 2008 have DSP events (illnesses and/or shellfish harvesting closures) become recognized as a threat to human health in the United States. This study characterized 20 strains representing five species ofDinophysisspp. isolated from three US coastal regions that have experienced DSP events: the Northeast/Mid‐Atlantic, the Gulf of Mexico, and the Pacific Northwest. Using a combination of morphometric and DNA‐based evidence, seven Northeast/Mid‐Atlantic isolates and four Pacific Northwest isolates were classified asD. acuminata, a total of four isolates from two coasts were classified asD. norvegica, two isolates from the Pacific Northwest coast were identified asD. fortii,and three isolates from the Gulf of Mexico were identified asD. ovumandD. caudata. Toxin profiles ofD. acuminataandD. norvegicavaried by their geographical origin within the United States. Cross‐regional comparison of toxin profiles was not possible with the other three species; however, within each region, distinct species‐conserved profiles for isolates ofD. fortii,D. ovum, andD. caudatawere observed. Historical and recent data from various State and Tribal monitoring programs were compiled and compared, including maximum recorded cell abundances ofDinophysisspp., maximum concentrations of OA/DTXs recorded in commercial shellfish species, and durations of harvesting closures, to provide perspective regarding potential for DSP impacts to regional public health and shellfish industry.
