Early-Late 2002: Scientists Map Anthrax Genome to Help Anthrax Attacks Investigation, but Make No Breakthroughs

Claire Fraser-Liggett.Claire Fraser-Liggett. [Source: University of Maryland]In late 2001, the FBI decides to try to decode the entire DNA sequence of the anthrax genome in an attempt to generate new leads for its anthrax attacks investigation. There are about five million units in the genome. The Institute for Genomic Research (TIGR), a leader in decoding microbe genomes, is given this task. TIGR director Claire Fraser-Liggett forms a small team of scientists. By early 2002, this TIGR team completes the genome. Then they compare the anthrax used in the letter sent to the Sun tabloid to a sample of the same strain, the Ames strain, maintained at Porton Down, the British biological weapons facility. The team finds several differences between the samples, raising the possibility that they could learn exactly which laboratory the anthrax used in the attacks came from. The team then looks at the original Ames strain, taken from a dead cow in Texas in 1981, to attempt to see how the anthrax in the letter evolved from the original. By late 2002, this task is finished but investigators are disappointed to learn that there are almost no noticeable differences between the original Ames strain and the anthrax used in the attacks.
