CIDRAP News, Aug. 15, 2008 This Center for Infectious Disease Research and Policy article quotes UTMB's Dr. C. J. Peters about the strain of anthrax that the FBI says Dr. Bruce Ivins mailed in the wake of the 9/11 attacks. According to the FBI, Ivins killed himself just before he was to be indicted for the anthrax attacks.  Peters, along with other researchers, question the methodology used by the FBI in matching the anthrax in the letters to a batch of anthrax in Ivins's custody. From the article: Referring to the four mutations reported by the FBI, he{Peters} said, "They're talking about a substrain of the Ames strain. Well, where did that substrain arise? It arose during the preparation of the Ames strain. If Bruce Ivins propagated it and got this strain, and someone else propagated it, how do we know they didn't get the same substrain?" Peters said the FBI should publish its analysis in a scientific journal so that people who work in bacterial genomics can examine it. "I think it's something that can be done and must be done. If they don't do it, nobody's ever going to believe it," he said.
