Research finds female descendants susceptible to stress
August 26, 2014

ratsPULLMAN, Wash. – A new study by researchers from the University of Texas at Austin and Washington State University shows that male and female rats are affected differently by ancestral exposure to a common fungicide, vinclozolin. Female rats whose great-grandparents were exposed become much more vulnerable to stress.

PULLMAN, Wash. – Ellen Preece wants to know if microcystins, liver-damaging toxins produced by algal blooms in freshwater lakes, accumulate in Puget Sound seafood.


She’s not the only one who wants to know. Preece, a doctoral student in the WSU School of the Environment, is helping the Washington Department of Health determine whether seafood accumulates enough microsystins to be a health concern for populations who … » More …

Warm weather brings threat of ticks
April 10, 2007

PULLMAN- Warming weather in the Pacific Northwest brings with it a renewed threat of tick paralysis in animals and people. Tick paralysis is a somewhat uncommon but potentially fatal disease that can affect virtually all warm-blooded land animals. It occurs when certain species of ticks inject potent toxins from their salivary glands into the host animal. The disease was first identified in Australia in 1824. Since then, more than 60 species of ticks worldwide have been identified as toxin producers. At least two prominent species of ticks on the list of toxin producers are native to North America, including the Pacific Northwest. In fact, tick … » More …

Toxin, bioagent list expands
February 21, 2003

The Center for Disease Control and the U.S. Department of Agriculture on Feb. 7 approved a new set of regulations regarding the registration, monitoring and purchase of select biological agents and toxins. The new regulations, which apply to Washington State University, expanded the list of substances that must be registered and included hefty fines for those who fail to comply. “The Office of Grants and Research Development did a survey in the fall of potential biological agents and toxins on campus, but the number of agents has expanded,” said David Clark, research compliance officer for the Office of Research. “Washington State University needs to submit … » More …
