Abstract

Colibacillosis (CB) is a collective term which has been used to describe a group of diseases cause by the gram negative bacillus Escherichia coli. The disease affects neonatal calves, lambs, and piglets, weaned pigs and poultry. Certain E. coli also cause a diarrheal disease in human adults and infants. The research reported herein includes examination of 37 bovine E. coli strains to determine entero pathogenicity and the reliability of different assay methods, characterization of bovine LT ad comparison of bovine LT with porcine LT, comparison of three culture media to determine which one provides maximum ST production, and partial purification of bovine ST.
