ABSTRACT:

FIELD OF THE INVENTION
This invention relates to treatment of antibiotic associated diarrhea, including
Clostridium difficile
associated diarrhea (CDAD) and pseudomembranous colitis (PMC) and other conditions associated with
C. difficile
infection. More specifically, the invention concerns neutralization of
C. difficile
toxin B, a cytotoxin associated with CDAD, PMC and other conditions caused by
C. difficile.
