As the induction of the interferon-inducible ELR- CXC chemokines within the lungs of spore-challenged mice is associated with resistance to inhalational anthrax [22], we sought to determine whether murine CXCL9, CXCL10, and CXCL11 exert antimicrobial activity against B. anthracis Sterne strain. Here, CXCL9 is linked to anthrax infection.
