RcsB contributes to the distinct stress fitness among Escherichia coli O157:H7 curli variants of the 1993 hamburger-associated outbreak strains.

Abstract excerpt

Curli are adhesive fimbriae of Enterobactericaeae and are involved in surface attachment, cell aggregation, and biofilm formation. We reported previously that curli-producing (C(+)) variants of E. coli O157:H7 (EcO157) were much more acid sensitive than their corresponding curli-deficient (C(-)) variants; however, this difference was not linked to the curli fimbriae per se. Here, we investigated the underlying...
