Mutations in the csgD promoter associated with variations in curli expression in certain strains of Escherichia coli O157:H7.

Applied and environmental microbiology - 1 May 2001

Uhlich G A, Keen J E, Elder R O

Abstract excerpt

Single-base-pair csgD promoter mutations in human outbreak Escherichia coli O157:H7 strains ATCC 43894 and ATCC 43895 coincided with differential Congo red dye binding from curli fiber expression. Red phenotype csgD::lacZ promoter fusions had fourfold-greater expression than white promoter fusions. Cloning the red variant csgDEFG operon into white variants induced the red phenotype. Substrate utilization differed...
