Natural Toxins 7: 311-315 (1999) Evidence of saxitoxin derivates as causative agents in the 1997 mass mortality of monk seals in the Cape Blanc Peninsula
نویسندگان
چکیده
Monk seals in Cape Blanc (Western Sahara coast) suffered a mass mortality Turing May-July 1997 which was attributed to a morbilivirus. High performance liquid chromatography (HPLC) analysis on tissues of seals killed during the outbreak and on related fauna showed peaks with retention times coincident with those of some saxitoxin derivatives but their identity of these toxins by mass spectrometry (MS), supporting the hypothesis that this mortality of monk seals was caused by biotoxins rather than by a morbillivirus.
