title: Nucleotide sequence homology between the heat-labile enterotoxin gene of Escherichia coli and Vibrio cholerae deoxyribonucleic acid.
abstract: Isolated deoxyribonucleic acid fragments encoding the heat-labile enterotoxin of Escherichia coli were used to probe for homologous sequences in restricted whole-cell deoxyribonucleic acid from Vibrio cholerae. Significant sequence homology between the heat-labile enterotoxin gene and V. cholerae deoxyribonucleic acid was demonstrated, and apparent differences were observed in the organization of the cholera toxin gene among different strains of V. cholerae.
