Shipments from the United States to Iraq of the kinds of pathogens later used in Iraq's biological weapons programs, according to records from the Centers for Disease Control and Prevention, the Senate Banking Committee and U.N. weapons inspectors:

ANTHRAX

Iraq admitted making 2,200 gallons of anthrax spores and putting some of them into weapons. U.N. inspectors said Iraq could have made three times as much anthrax as it acknowledged, and could not verify Iraq's claims to have destroyed all of its weaponized anthrax.

The American Type Culture Collection, a biological samples repository in Manassas, Va., sent two shipments of anthrax to Iraq in the 1980s. Three anthrax strains were in a May 1986 shipment sent to the University of Baghdad, which U.N. inspectors later linked to Iraq's biological weapons program. A 1988 shipment from ATCC to Iraq also included four anthrax strains.

BOTULINUM

Iraq admitted making 5,300 gallons of botulinum toxin, a deadly poison produced by the Clostridium botulinum bacteria, and putting some of it into weapons. Five warheads filled with botulinum toxin are missing.

ATCC sent six strains of Clostridium botulinum to the University of Baghdad in the May 1986 shipment. The September 1988 ATCC shipment to Iraq also contained one strain of Clostridium botulinum.

In March 1986, the CDC sent samples of botulinum toxin and botulinum toxiod (used to make a vaccine against botulinum poisoning) directly to Iraq's al-Muthanna complex, a center for Iraq's chemical weapons program and the site where Iraq restarted its dormant biological weapons program in 1985.

GAS GANGRENE

U.N. inspectors concluded Iraq could have produced hundreds of gallons of the germs that cause gas gangrene, though Iraq admitted producing just a fraction of that amount. Gas gangrene, caused by the Clostridium perfringens bacteria, causes toxic gases to form inside the body, killing tissues and causing internal bleeding, lung and liver damage.

ATCC sent three strains of Clostridium perfringens to the University of Baghdad in the May 1986 shipment and another three strains in the 1988 shipment.

OTHER

The CDC sent bacteria samples to Iraq's Atomic Energy Commission in 1985, 1987 and 1988. The commission was involved in Saddam's attempts to build a nuclear bomb and other weapons of mass destruction.

The CDC also sent bacteria samples to the Sera and Vaccine Institute in Amiriyah, Iraq in 1988. The institute stored samples and did genetic engineering research for Iraq's biological weapons programs, U.N. inspectors found.
