The Road to Toxin-Targeted Therapeutic Antibodies

ABSTRACT Once an infection by a toxin-producing bacterium is well established, therapies such as antibiotics that target bacterial growth may have little impact on the ultimate patient outcome. In such cases, toxin-neutralizing antibodies offer an opportunity to block key virulence factors. New work...
