Few microorganisms are as versatile as Escherichia coli. An important member of the
normal intestinal microflora of humans and other mammals, E. coli has also been widely …

Although Escherichia coli can be an innocuous resident of the gastrointestinal tract, it also
has the pathogenic capacity to cause significant diarrheal and extraintestinal diseases …

Escherichia coli is a remarkable and diverse organism. This normally harmless commensal
needs only to acquire a combination of mobile genetic elements to become a highly adapted …

Wiskott–Aldrich syndrome protein (WASP) and WASP-family verprolin-homologous protein
(WAVE) family proteins are scaffolds that link upstream signals to the activation of the …

▪ Abstract Eukaryotic cells use actin polymerization to change shape, move, and internalize
extracellular materials by phagocytosis and endocytosis, and to form contractile structures …

Helicobacter pylori strains associated with severe tissue damage and inflammation possess
a unique genetic locus, cag, containing 31 genes originating from a distant event of …

Neutrophils exposed to chemoattractants polarize and accumulate polymerized actin at the
leading edge. In neutrophil-like HL-60 cells, this asymmetry depends on a positive feedback …

The human pathogen Helicobacter pylori colonizes the mucous layer of the stomach. During
parasitic infection, freely swimming bacteria adhere to the gastric epithelial cells and trigger …

Escherichia coli is the most abundant facultative anaerobic gram-negative bacterium of the
intestinal microffora, naturally colonizing the mucous layer of the colon. A conserved core …

Enteropathogenic Escherichia coli (EPEC) is a gram-negative bacterial pathogen that
adheres to intestinal epithelial cells, causing diarrhoea. It constitutes a significant risk to …
