Pfiesteria piscicidaA dinoflagellate species that periodically causes algal blooms in estuaries along the Atlantic seaboard of the US, which kills fish by releasing a potent neurotoxin. There have been anecdotal reports that Pfiesteria piscicida may also affect humans, causing an array of symptoms including headache, confusion, skin rash and eye irritation, but the public health impact of P piscicida is unknown.
Pfiesteria piscicida(fēs-tĕr′ē-ă pĭs-ĭ-sīd′ā) [NL fish killer]
A unicellular marine organism, which may or may not produce a toxin, depending on environmental conditions. When toxic, it has been implicated in the death of millions of fish in the estuaries of North Carolina, Delaware, and Maryland. The toxin can become aerosolized, and if humans are exposed to it, severe neurological, mental, and physical illness may occur. Specific therapy to combat the toxin is not available, but concomitant infections can be treated with tetracyclines.
