Classification and identification of Pfiesteria and Pfiesteria-like species.
Dinoflagellates can be classified both botanically and zoologically; however, they are typically put in the botanical division Pyrrhophyta. As a group they appear most related to the protistan ciliates and apicomplexans at the ultrastructure level. Within the Pyrrhophyta are both unarmored and armored forms of the dominant, motile flagellated stage. Unarmored dinoflagellates do not have thecal ...
متن کاملPfiesteria piscicida and Dinoflagellates Similar to Pfiesteria
Pfiesteria pisiccida is a microscopic, unicellular organism that is classified as both a mixotrophic and heterotrophic dinoflagellate, which has been associated with both fish deaths and a cause of human illness (Burkholder et al., 1992; Glasgow et al., 1995; Burkholder and Glasgow, 1997). This species possesses a complex life cycle that includes motile forms (e.g. zoospores, gametes, amoebae) ...
متن کاملRemember Pfiesteria?: Occupational Exposure Unlikely to Cause Cognitive Effects
Information was obtained on the health status or cause of death in the mothers of a population-based series of 143 children with soft tissue sarcomas. Among these mothers there were 6 cases of breast cancer. All 6 women were pre-menopausal and 2 had bilateral disease. This represents a significant 3-fold excess risk of breast cancer. Malignant disease had occurred in 6 other women whose ages at...
متن کاملPfiesteria piscicida Bibliography
The presence of P. piscicida in Chesapeake Bay is documented. The appearance and behavior of the algae and symptoms associated with fish mortality were consistent with those previously observed in P. piscicida-associated aquaria fish kills in North Carolina. The discovery of P. piscicida in Chesapeake Bay shows that dinoflagellates have a dramatic and far-reaching impact on fish stocks in shall...
متن کاملCharacterization of Pfiesteria ichthyocidal activity.
Article: Drgon et al. (4) concluded that the “aquarium bioassay format is unsuitable to accurately assess the ichthyocidal activity of Pfiesteria spp.” and “ichthyocidal activity of Pfiesteria spp. is mostly due to direct interactions of the zoospores with fish skin and gill epithelia rather than to soluble factors.” These conclusions are not justified, because microbial community analyses of c...
