Anthrax
bacteria likely to be US military strain
by Debora MacKenzie
THE bacteria used for the anthrax attacks in the US is either the strain the US itself used to make anthrax weapons in the 1960s, or close to it. It is not a strain that Iraq, or the former Soviet Union, mass-produced for weapons.
There have been charges over the past week that the sophistication of the anthrax suggests that it was produced with the backing of some government, such as Iraq. But neither the strain nor the physical form of the anthrax is particularly sophisticated, say bioweapons specialists.
