Human noroviruses (HuNoV) are the primary cause of foodborne disease outbreaks in the United States. The most frequent commodities implicated in HuNoV outbreaks are leafy greens where contamination may occur during production and harvesting practices. With respect to transmission of HuNoV to fresh produce, one hypothesis is that free-living amoebae that are ubiquitous in the environment (soil,...

H-NS is a well-established silencer of virulence gene transcription in the human pathogen Vibrio cholerae. Biofilm formation aids V. cholerae in colonizing both its host and its external environments and H-NS silences biofilm gene expression. Cyclic-di-guanosine monophosphate acts through the DNA binding proteins VpsR and VpsT to overcome H-NS-mediated repression of biofilm genes, driving a...

Expression of Vibrio cholerae genes required for the biosynthesis of exopolysacchide (vps) and protein (rbm) components of the biofilm matrix is enhanced by cyclic diguanylate (c-di-GMP). In a previous study, we reported that the H-NS protein represses the transcription of vpsA, vpsL and vpsT. Here we demonstrate that the regulator VpsT can disrupt repressive H-NS nucleoprotein complexes at the...

The diarrheal pathogen Vibrio cholerae contains 3 gene clusters that encode chemotaxis-related proteins, but only cluster II appears to be required for chemotaxis. Here, we present the first characterization of V. cholerae's “cluster III” chemotaxis system. We found that cluster III proteins assemble into foci at bacterial poles, like those formed by cluster II proteins, but the two systems...

Salmochelins are glucosylated forms of enterobactin (enterochelin) and contribute to virulence of Salmonella enterica and some extra-intestinal pathogenic E. coli (ExPEC). Fes, IroD and IroE esterases degrade salmochelins and enterobactin to release iron. We investigated the apparently redundant role of these esterases in virulence and in salmochelin production and utilisation of the ExPEC strain...
