ABSTRACT The intestine is a complex, ever-changing environment replete with an array of signaling molecules.To colonize such a complex organ, pathogens have adapted to utilize specific cues from the local environment to intricately regulate the expression of their virulence determinants.Salmonella preferentially colonizes the distal ileum, a niche
The microtopography associated with ice-wedge polygons governs many aspects Saucers of Arctic ecosystem, permafrost, and hydrologic dynamics from local to regional scales owing to the linkages between microtopography and the flow and storage of water, vegetation succession, and permafrost dynamics.Wide-spread ice-wedge degradation is transforming l
