Bacillus anthracis
Anthrax is a bacterium that disperses in the form of 'spores'. These spores invade their host and cause varying amounts of damage dependent on the strain of anthrax, the grade of anthrax and the area of the body it colonises.
DIFFERENT STRAINS
Bacteria live in colonies. They reproduce very quickly and thus changes in their genetic material happens more often. Having different genes renders different families of the bacteria, often known as different strains. Certain genes make the bacteria more hardy, and more deadly. Using molecular biological techniques, Microbiologists can trace the origins and understand the pathologies of the strain.
WHAT IS MILITARY GRADE?
There are different forms of bacteria, which can enter the body in different ways. The most lethal type, which has been recently termed "inhalation anthrax" is ingested in the form of a powder which contains the airborne particles. To achieve maximum capability of penetrating the lung, particles should be around 1 - 5 microns in size (each single bacterial spore measures 0.5 micron)
Normally the wet bacterial colonies clump together to achieve the small size, colonies need to be ground down. However as the bacterial spores dry they expand in size and have a slight electrical charge. This charge encourages the particles to cling to surfaces, rather than remain airbourne where they can then be inhaled.
In order to eliminate this electrical charge certain 'manufacturers' developed chemicals that caused the particles to remain separate and some developed additives that would remove the charge to create a neutrally charged floating particle.
Looking at the variety of chemicals added to the particles may help indicate the source of the anthrax outbreak
