Trusted: edited by a thematic editorHarmful effect HPLC-FD analysis of one sample of picked cells of Japanese strains of D. rotundata found it containing DTX1 (101 pg/cell)(Lee et al. 1989).
No toxins detected in HPLC-FD analyses of dense blooms of P. rotundatum (as Dinophysis rotundata) from eastern Canada (Cembella 1989) and Italy (Caroppo et al. 1999).
No toxins in picked cells analyzed by LC-MS in Japan (Suzuki et al. 2009).
When P. rotundatum was found co-occurring with toxic species of Dinophysis (D. acuminata, D. acuta, D. norvegica, D. caudata), LC-MS analyses of picked cells showed either small amounts of the same toxins (OA, DTXs, PTXs) present in the co-occurring Dinophysis species or no toxins at all (Miles et al. 2004; González-Gil et al. 2011).
Miles et al. (2004) found the same toxins in 3 heterotrophic species of Protoperidinium co-occurring with the same multispecific bloom (D. acuminata, D. acuta, D. norvegica and P. rotundatum).
There is growing suspicion that P. rotundatum is not a toxin-producer de novo, but may contain DSP toxins and act as a vector after feeding on tintinnids who preyed on toxic Dinophysis (reviewed in González-Gil et al. 2011).
