[Differentiation of Shigella flexneri serotype 6 from serotypes 1-5 by electrophoresis and isoelectric focusing of their elastases].

Abstract

Among Shigella flexneri serotypes, serotype 6 (28 strains) was individualized from serotypes 1 to 5 (43 strains) by electrophoresis and isoelectric focusing of esterases. The taxonomic status of S. flexneri serotype 6 should be reconsidered in light of this work.
