Relationships among raffinose plasmids determined by the immunochemical cross-reaction of their alpha-galactosidases.

Abstract

Plasmid-encoded alpha-galactosidase served as a marker enzyme for the recognition and comparison of raffinose (Raf) plasmids present in strains of Escherichia coli. Immunochemical relationships were established among Raf plasmids of 39 independent isolates from man and domestic animals (from three continents) by using antiserum against alpha-galactosidase. Immunodiffusion revealed three serological subclasses of alpha-galactosidase, which are correlated with the biological and geographical origin of the host strains. It is concluded that the raf determinants of all Raf plasmids tested have evolved from a common ancestor.
