Changing Diagnostic Methods And Increased Detection Of Verotoxigenic Escherichia Coli, Ireland, Thomas Rice, Noreen Quinn, Roy D. Sleator, Brigid Lucey

The recent paradigm shift in infectious disease diagnosis from culture-based to molecular-based approaches is exemplified in the findings of a national study assessing the detection of verotoxigenic Escherichia coli infections in Ireland. The methodologic changes have been accompanied by a dramatic increase in detections of non-O157 verotoxigenic E. coli serotypes.

The 40-Residue Insertion In Vibrio Cholerae Fadr Facilitates Binding Of An Additional Fatty Acyl-Coa Ligand, Wei Shi, Gabriela Kovacikova, Wei Lin, Ronald. K. Taylor, Karen Skorupski, F. Jon Kull

FadR is a master regulator of fatty acid metabolism and influences virulence in certain members of Vibrionaceae. Among FadR homologues of the GntR family, the Vibrionaceae protein is unusual in that it contains a C-terminal 40-residue insertion. Here we report the structure of Vibrio cholerae FadR (VcFadR) alone, bound to DNA, and in the presence of a ligand, oleoyl-CoA. Whereas Escherichia coli FadR (EcFadR) contains only one acyl-CoA-binding site in each monomer, crystallographic and calorimetric data indicate that VcFadR has two. One of the binding sites resembles that of EcFadR, whereas the other, comprised residues from the insertion, has not …
