title: [Characteristics of the B subunit of a thermolabile Escherichia coli enterotoxin produced by the A-B+ E. coli strain].
abstract: The preparation and identification of B subunit of thermolabile enterotoxin produced by A-B+ gene-containing strain are described. The E. coli strain studied is shown to produce protein identical in its molecular properties and antigenic specificity to B subunit obtained from the whole thermolabile enterotoxin. Partial antigenic affinity between B subunits of thermolabile enterotoxin obtained from different sources and B subunit from cholera enterotoxin has been established in immunochemical studies. Electrophoretic and immunochemical analysis has confirmed the absence of A-subunit admixtures in B-subunit preparation obtained from /A-B+/E. coli strain.
