Norepinephrine has been shown to increase the expression of K99 pilus adhesin of enterotoxigenic E. coli (Lyte et al., 1997c) as well as type 1 fimbriae of commensal E. coli (Hendrickson et al., 1999).

Norepinephrine was found to increase E. coli O157:H7-induced intestinal inflammatory and secretory responses as well as bacterial adherence to intestinal mucosa.

Nakano et al. (2007b) found that norepinephrine enhanced the cytotoxicity and enterotoxicity of V. parahaemolyticus, as well as increased transcription of several Type III secretion system TSS1related genes.

Recently, Cogan et al. (2007) also found that norepinephrine increased the host cell invasiveness of Campylobacter jejuni.
