Inhibitory activities of colicins against Escherichia coli strains responsible for postweaning diarrhea and edema disease in swine.

The efficacies of colicins E1 and N against Escherichia coli strains responsible for postweaning diarrhea and edema disease, two of the most prevalent disease problems for pigs in the United States, were determined in vitro. These proteins may provide an environmentally sound means for the prevention of these infections in swine.
