Geospatial analysis reveals a hotspot of fecal bacteria in Canadian prairie lakes linked to agricultural non-point sources

Author(s): Oliva A; Onana VE; Garner RE; Kraemer SA; Fradette M; Walsh DA; Huot Y;

Lakes are sentinels of environmental changes within their watersheds including those induced by a changing climate and anthropogenic activities. In particular, contamination originating from point or non-point sources (NPS) within watersheds might be reflec ...

Gut colonization by Proteobacteria alters host metabolism and modulates cocaine neurobehavioral responses

Author(s): Cuesta S; Burdisso P; Segev A; Kourrich S; Sperandio V;

Gut-microbiota membership is associated with diverse neuropsychological outcomes, including substance use disorders (SUDs). Here, we use mice colonized with Citrobacter rodentium or the human ?-Proteobacteria commensal Escherichia coli HS as a model to exam ...

Evidence of an intracellular interaction between the Escherichia coli enzymes EntC and EntB and identification of a potential electrostatic channeling surface

Author(s): Ouellette S; Pakarian P; Bin X; Pawelek PD;

Siderophores are high-affinity small-molecule chelators employed by bacteria to acquire iron from the extracellular environment. The Gram-negative bacterium Escherichia coli synthesizes and secretes enterobactin, a tris-catechol siderophore. Enterobactin is ...
