U.S. Army Lab Freezes Research on Dangerous Pathogens

The U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) has suspended research activities involving biological select agents and toxins. Army officials took the step on Friday after discovering apparent problems with the system of accounting for high-risk microbes and biomaterials at the Fort Detrick, Maryland, facility.

The lab has been under intense scrutiny since August, when the Federal Bureau of Investigation (FBI) named former USAMRIID researcher Bruce Ivins as the perpetrator of the 2001 anthrax letter attacks. Although the case never went to trial because of Ivins's suicide on 29 July 2008, FBI officials have claimed that the evidence against him is indisputable and that he carried out the mailings using anthrax stolen from a flask at USAMRIID.

Officials have begun a complete inventory of all select agents and toxins at the facility. All experiments using select agents will remain suspended until the accounting is finished, which could take several weeks. Several USAMRIID researchers have been grumbling about the decision, which seems to have caught them by surprise, according to a government official not connected to the lab.
