These bacteria also produce large amounts of vitamins, especially vitamin K and biotin ( a B vitamin ), for absorption into the blood.

These feelings may provoke a strong urge to escape or flee the place where the attack began ( a consequence of the sympathetic " fight-or-flight response ") in which the hormone which causes this response is released in significant amounts.

These alleged refugees claimed the ancestry of Sargon of Akkad ( whose dynasty died out some 15 centuries before the fall of Assyria ), they also contradictionally claimed ancestry from Nabopolassar, a Babylonian king of Chaldean extraction who played a major part in the destruction of the Assyrian Empire.

The late author Sheldon H. Harris in his book " Factories of Death: Japanese Biological Warfare, 1932-1945, and the American cover up " wrote that, The test program, could be part of Project AGILE or Project OCONUS which began in fall 1962 and which was funded at least through fiscal year 1963, was considered by the Chemical Corps to be “ an ambitious one .” The tests were designed to cover “ not only trials at sea, but Arctic and tropical environmental tests as well .” The tests, presumably, were conducted at what research officers designated, but did not name, “ satellite sites .” These sites were located both in the continental United States and in foreign countries.

These pathogens fall into two broad categories, bloodborne ( carried in the body fluids ) and airborne.

These " proofs ", however, would fall apart if it turned out that the hypothesis was false, so there is considerable interest in verifying the truth or falsity of conjectures of this type.
