Effects of the estuarine dinoflagellate Pfisteria
shumwayae (Dinophyceae) on survival and grazing activity of several shellfish species.
The NCSU culture contains both Pfisteria
piscicida and Pseudofisteria shumwayae and represents the natural estuarine environment.
The event resulted in fish lesions consistent, in the opinions of biologists who examined the fish, with exposure to the toxic dinoflagellate Pfisteria
For example, during a pfisteria
crisis, many groups took the outbreak on as their issue.
This technology will allow instant detection and continuous tracking of a variety of substances that could contaminate our water supply, from an oil spill to Pfisteria
," said John F.
Elevated levels of organic nutrients may favor proliferation of the microbe Pfisteria
, which can kill fish and may even threaten human health.
The discharge of animal processing and human wastes into surface waters can make them unsafe for drinking and recreation and can promote the growth of microorganisms such as pfisteria
which can be harmful to fish, wildlife and humans.
At the request of the state health agency, comprehensive examinations were conducted in a cross-sectional prevalence study of watermen working where Pfiesteria exposure may occur: waters where diseased or stressed fish were reported from June to September 1997, and where Pfisteria
had been identified in the past.
Another resolution, proposed from the floor by Councilmember Max Freeze, New Bern, North Carolina, encourages research into Pfisteria
-- an algae that attacks fish.
Most of the major environmental health issues of our day, including global warming, endocrine disruptors, the causes of malformed frogs, and toxic organisms such as Pfisteria
emphasize the need to seek and define this common ground in our research strategies and in our health policy decisions.
