* Benign: Sterne (used as vaccine)
 
''Virulence factors that distinguish Bacillus anthracis from Bacillus cereus are encoded on two plasmids, pXO1 (anthrax toxin) and pXO2 (capsule genes). The capsule protects against phagocytosis once the vegetative bacterium enters the bloodstream. The anthrax toxin consists of 3 components, a protective antigen (PA), lethal factor (LF), and edema factor (EF). PA/LF and PA/EF complexes are internalized by host cells where the LF (metalloprotease) and EF (calmodulin-dependent adenylate cyclase) components act. At high levels LF induces cell death and release of the bacterium while EF increases host susceptibility to infection and promotes fluid accumulation in the cells. (NCBI)

* Ames, AmesAncestor, Stern are 99.9% identical; no rearrangements
* The chromosome and plasmids don't seem to share sequence; few < 2Kb alignments at < 92%id

Background

  • 89 known strains
  • Most virulent: Ames(USA 2001), Vollum (WWII, biological weapon)
  • Benign: Sterne (used as vaccine)

Virulence factors that distinguish Bacillus anthracis from Bacillus cereus are encoded on two plasmids, pXO1 (anthrax toxin) and pXO2 (capsule genes). The capsule protects against phagocytosis once the vegetative bacterium enters the bloodstream. The anthrax toxin consists of 3 components, a protective antigen (PA), lethal factor (LF), and edema factor (EF). PA/LF and PA/EF complexes are internalized by host cells where the LF (metalloprotease) and EF (calmodulin-dependent adenylate cyclase) components act. At high levels LF induces cell death and release of the bacterium while EF increases host susceptibility to infection and promotes fluid accumulation in the cells. (NCBI)

  • Ames, AmesAncestor, Stern are 99.9% identical; no rearrangements
  • The chromosome and plasmids don't seem to share sequence; few < 2Kb alignments at < 92%id
