In 1980, the species taxonomic status was raised to variety, based on morphological variations in the motile stage, the capability of PSP toxin production, and the geographic distribution (Steidinger et al., 1980). Salud. For quantitative analysis, light microscopy is used to estimate the cell density by the Utermöhl (Hasle, 1978) or Sedgewick-Rafter (Guillard, 1978) methods. Eng. (2011, 2013); Meave-del Castillo et al. Pyrodinium bahamense var. Inst. Epidemiological numbers of outbreaks of food poisoning related to P. bahamense, reveal that this dinoflagellate is the major source of PSP in Mexico. Notas sobre algunos dinoflagelados planctónicos marinos de México con descripción de nuevas especies. 6:1. doi: 10.3389/fmars.2019.00001. The author thank Dr. Andrea Murillo from Biotechnologika A2 for critically reading of the manuscript. 69, 285–317. “Preservation and storage,” in Phytoplankton Manual Monographs on Oceanographic Methodology, Vol. Deep Sea Res. Pyrodinium bahamense, along with many other dinoflagellates, are known for secreting toxins that cause Paralytic Shellfish Poisoning (PSP). The species naturally produces the toxin, but as the lagoon gains excess nutrients via runoff from land, the algae have the potential to bloom more often and severely, leading to more saxitoxins being introduced into the food web. doi: 10.1016/j.marpolbul.2011.01.009. Here, we tested 48 cultivable pelagic bacteria from three HAB-affected areas in the Philippines (Bolinao, Sorsogon, and Matarinao) against non-axenic cultures of the toxic, thecate dinoflagellate Pyrodinium bahamense.

Martínez-López, A., Ulloa-Pérez, E., and Escobedo-Urias, D. (2007). 100, 405–487. The data obtained so far on P. bahamense spatial and population variability in Mexican Pacific and the Gulf of Mexico, suggest a seasonal and latitudinal pattern. A.

A., Ceballos-Corona, G., Herrera-Silveira, J., et al. This prevents, in the short term, the establishment of management plans to minimize HABs impacts as well as the advance of the understanding and prediction of them. Biol. Bot. Although it was widely believed that the compressum variety is toxic and found in the Pacific while the bahamense variety is nontoxic and found in the Atlantic, a 1972 toxic algal bloom of Pyrodinium bahamense in Papua New Guinea showed that P. bahamense could also be toxic. These are Pyrodinium bahamense and Gymnodinium catenatum (Mons et al., 1998). Also, in these regions, the abundance, seasonality, and species distribution tend to decrease from tropical to subtropical areas. Also, they have highlighted the importance of carrying out comparative studies between the western Pacific and tropical Atlantic populations, to understand better the factors that play essential roles in the bloom dynamics and toxicity of the species.
