Binding agents able to disrupt bacterial biofilms of diverse origin are described, including monoclonal antibodies secreted by human B lymphocytes. Methods to prevent formation of or to dissolve biofilms with these binding agents are also described. Immunogens for eliciting antibodies to disrupt biofilms are also described.

Novel, antibody-based binding agents derived from camelid V.sub.HH and human immunoglobulins are described. These binding agents recognize and bind with specificity to Clostridium difficile toxin A and/or toxin B and in some cases exhibit toxin neutralizing activity. These binding agents can be used to treat or prevent primary and recurrent CDI. The binding agents include humanized V.sub.HH peptide monomers, linked groups of humanized V.sub.HH peptide monomers, humanized V.sub.HH peptide monomers joined to antibody Fc domains, and humanized V.sub.HH peptide monomers joined to IgG antibodies.
