Bourdelais et al. (2002) identified BTXs PbTx-2, PbTx-3, and PbTx-9 in seawater samples from the Delaware coast, USA associated with fish kills and a bloom of Chattonella cf. verruculosa. The identity of the toxins was confirmed by chromatographic, immnnochemical, nuclear magnetic resonance spectroscopy and mass spectrographic analyses, and the toxin content of cells was inferred from cell counts and toxin concentrations, to be on the order of 6 pg /cell. This is comparable to the levels found in Florida K. brevis (Table 21.1). However, despite this strong circumstantial association, it has not yet been possible to demonstrate BTX production by cultures of Ch. cf. verruculosa isolated from Delaware coast waters (Bourdelais, pers. comm.)...
