Molecular Basis of Pathogenicity in Enteric Bacteria
Abstract
A new quantitative assay for the determination of the E. coli heat- stable enterotoxin has been developed which is about 10-fold more sensitive than existing methods. A strategy for the development of subunit vaccines has been tested using specific peptides of the binding region of cholera toxin. Although there have been numerous reports of the relationship between E. coli LT toxin (and cholera toxin) and a putative enterotoxin of Salmonella typhimurium, we have been unable to demonstrate any DNA sequence homology between known toxin sequences of E. coli LT, ST or cholera toxin with the nucleic acid of Salmonella.
