Identification and Characterization of Species of the Family Bacteriodaceae by Polyacrylamide Gel Electrophoresis

Abstract

A method is described for identifying and characterizing microorganisms of the family Bacteroidaceae by their protein profiles. Protein profiles of six species and several strains of this family were compared using gradient polyacrylamide gel electrophoresis in the slab form. The protein profiles were sufficiently distinct and reproducible to allow identification of species, subspecies, and even minor strain differences. This technique is suggested as an adjunct to the present methods of characterization and identification of these microorganisms.
