Abstract

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