The Gram-positive pathogen Bacillus anthracis causes anthrax, a fulminant and lethal infection of mammals. Two large virulence plasmids, pXO1 and pXO2, harbour genes required for anthrax pathogenesis and encode secreted toxins or provide for the poly gamma-d-glutamic acid capsule. In addition to capsule, B. anthracis harbours additional cell wall envelope structures, including the surface layer (S-layer), which is composed of crystalline protein arrays. We sought to identify the B. anthracis envelope factor that mediates adherence of vegetative forms to human cells and isolated BslA (B. anthracisS-layer protein A). Its structural gene, bslA, is located on the pXO1 pathogenicity island (pXO1-90) and bslA expression is both necessary and sufficient for adherence of vegetative forms to host cells. BslA assembly into S-layers and surface exposure is presumably mediated by three N-terminal SLH domains. Twenty-three B. anthracis genes, whose products harbour similar SLH domains, may provide additional surface molecules that allow bacilli to engage cells or tissues of specific hosts during anthrax pathogenesis.
