Harmful effect Gambierdiscus caribaeus produces 44-methylgambierone, but no gambierone (Murray et al. 2019, 2021). It is positive to the Human erythrocyte lysis assay (Holland et al. 2013). Mudge et al. (2023) identified a novel C-CTX analogue, C-CTX5, from Gambierdiscus caribaeus strains from the Caribbean. Metabolism in vitro by fish liver microsomes converted algal C-CTX5 into C-CTX1/2, the dominant CTX in ciguatoxic fish from the Caribbean. [details]
