Exposure to Pfisteria Piscicida

Exposure to Pfisteria Piscicida (history)


Presentation

  • This case is presented in an effort to contribute to the gradually accruing evidence of potential central nervous system sequelae of Pfiesteria exposure.[ncbi.nlm.nih.gov]

Respiratory Distress
  • Respiratory distress, neurological dysfunction, and a cloudiness of the skin with acute mortalities were reported in early laboratory studies (Smith and others, 1988; Noga and others, 1993).[pubs.usgs.gov]

Abdominal Cramps
Abdominal Pain
  • Burkholder and her assistant, Howard Glasgow, experience abdominal pains, mood swings, and mental impairment after being around Pfiesteria.[nytimes.com]
Skin Ulcer
  • In these studies, fish exposed to A. invadans develop skin ulcers without exposure to Pfiesteria species.[vims.edu]
  • The absence of skin lesions in the moribund and dead fish in the bioassay was inconsistent with previous reports describing skin ulcers as the result of toxic activity by Pfiesteria spp. ( 5 ).[aem.asm.org]

  • deficits in rats. [6] Taxonomy [ edit ] Based on 2005 research, the organism previously known as Pfiesteria shumwayae should be reassigned its own genus, based on both morphological analysis and molecular evidence as supported by rDNA analysis.[en.wikipedia.org]
