For the past 37 years, a small research lab in Beltsville, Maryland, has been the world’s leading hub for scientists working on Toxoplasma gondii, a parasite that infects more than 1 billion people globally, causing death, blindness, and birth defects. Operated by the U.S. Department of Agriculture (USDA), the facility is a source of expertise and rare, sought-after materials for researchers working to stop the parasite, which can be transmitted by food and has no human vaccine and no cure.
But last week, the lab fell victim to pressure from animal welfare activists and members of Congress concerned about its use of cats, the only animal in which T. gondii completes the sexual stages of its life cycle. USDA abruptly announced it was shutting down the lab’s work, saying the program, which cost $625,000 annually to operate, had “reached its maturity” and “achieved” its agricultural research goals.
The 2 April decision, which lab chief Jitender Dubey learned about from media reports, has left researchers scrambling for alternatives. “I’m really angry about this,” says Laura Knoll, a parasitologist at the University of Wisconsin in Madison who relies on samples from the laboratory. During a December 2018 external review of the lab she took part in, she says, “The validity and necessity of the research never seemed to be in question.” (USDA declined to answer a list of questions from Science and denied a request to interview Dubey.)
