Bacterial clump formation at the surface of liquid culture as a rapid test for identification of enteroaggregative Escherichia coli

J Clin Microbiol. 1993 May;31(5):1397-9. doi: 10.1128/jcm.31.5.1397-1399.1993.

Abstract

Forty-one strains of enteroaggregative Escherichia coli formed clumps visible as a scum at the surface of a Mueller-Hinton broth shaker culture. Sixty-one control strains of E. coli did not. Scum formation is a simple, rapid, and inexpensive test for the identification of enteroaggregative E. coli.
