with exposure to more hosts. A sub-strain called Vollum 1B was weaponized and was used in American warheads during the 1960s, but its origin is controversial. One theory that originated from a bio weapons veteran,
William C. Patrick III, is that Vollum 1B came from being altered when the microbiologist
William A. Boyles inhaled anthrax spores on the job. According to him, the "B" is there to stand for Boyles. A competing theory is based on the fact that during the 1940s and 1950s, a
British biological weapons program worked to enhance the virulence of the strain by passing it through a series of monkey hosts, which created a sub-strain of the Vollum strain called "M36". In papers that reference this "M36" sub-strain, it is called the Vollum 1B strain.
The M36 Vollum was reliably virulent, as opposed to other newly mutated strains, and thus it was chosen along with other
