title: Linkage of heat-stable enterotoxin activity and ampicillin resistance in a plasmid isolated from an Escherichia coli strain of human origin.
abstract: In an Escherichia coli strain of human origin, ampicillin resistance and heat-stable enterotoxin activity were shown by EcoRI restriction endonuclease and genetic analysis to be in an 80-megadalton plasmid.
