Isopycnic separation of Escherichia coli cultures possessing colonization factor antigen I

Abstract

A culture of Escherichia coli possessing colonization factor antigen I was subjected to isopycnic separation on Percoll gradients. The results demonstrated successful division of the culture into two populations: (i) bacteria which cause mannose-resistant hemagglutination and (ii) bacteria which lack the ability to hemagglutinate in the presence of mannose.
