Methods, Strains of Pfiesteria Both Critical in Determining Organism’s Toxicity
North Carolina State UniversityTo gauge the toxicity of Pfiesteria, the important single-celled fish predator that was the culprit behind a number of fish kills and fish diseases along the East Coast in the 1990s, researchers need to both use the proper study methods and recognize that certain populations of the organism, called strains, are toxic while others are not.
