Inhaling a clump of spores not much larger than a speck of dust can result in death. terrorism threats War on terrorism 2 game. Anthrax is contracted most commonly by workers who handle wool, hides, or other materials from diseased animals. About 20 percent of untreated cases of cutaneous infection result in death. Ingested spores kill in 20 to 60 percent of cases; and 90 percent or more of those who become infected through inhalation die within a few days. terrorism threats Pnumber of plane in terrorist attack. The battlefield use of anthrax is plausible-more than a dozen countries have the weapon or are developing one, according to Pentagon officials. Until recently, laboratories could readily order anthrax cultures from U. S. terrorism threats Terrorist attacks on the u.s.. suppliers. Before the Soviet Union abandoned its bioweapons program, Soviet scientists not only harvested anthrax spores in large quantity for use as a weapon, they also developed a highly effective dispersant that could quickly spread an invisible cloud of concentrated spores over a battlefield or a city. This dispersal technology may have been transferred to other countries. The United States also experimented with anthrax as a weapon. Would a vaccinated population of U. S. soldiers on a battlefield be fully protected? If strains were used against which the immunization was completely effective, the answer would be "Yes, for a little while. " However, sending a large number of immunized individuals into contact with enormous numbers of bacteria would almost certainly reveal spontaneous mutants against which the vaccine was no longer effective. An "evolutionary arms race" would begin, pitting the human ability to develop new vaccines against the microbes' ability to respond through natural selection-a bitter struggle we are all too familiar with in the case of newly arising variants of flu viruses that repeatedly make previous flu vaccines obsolete. The same battle is occurring in the growing resistance of pathogenic bacteria to antibiotics. Based on animal testing, the U. S. vaccine does not offer protection against all strains of anthrax.
