Enteropathogenic E. coli Interactions with Host Cells

Enteropathogenic E. coli interactions with host cells.

Enteropathogenic E. coli (EPEC) interacts with intestinal epithelial cells, causing diarrhea and associated diseases. This pathogen binds to epithelial cells using sophisticated mechanisms that exploit existing epithelial signal transduction pathways and host cytoskeletal components, ultimately resulting in the bacterium resting upon a pedestal on host cell surfaces. Recent data indicates that ...

Exploitation of host cells by enteropathogenic Escherichia coli.

Microbial pathogens have evolved many ingenious ways to infect their hosts and cause disease, including the subversion and exploitation of target host cells. One such subversive microbe is enteropathogenic Escherichia coli (EPEC). A major cause of infantile diarrhea in developing countries, EPEC poses a significant health threat to children worldwide. Central to EPEC-mediated disease is its col...

Enterohemorrhagic Escherichia coli (EHEC) and enteropathogenic E. coli

Interactions and predicted host membrane topology of the enteropathogenic Escherichia coli translocator protein EspB.

Type 3 secretion systems (T3SSs) are critical for the virulence of numerous deadly Gram-negative pathogens. T3SS translocator proteins are required for effector proteins to traverse the host cell membrane and perturb cell function. Translocator proteins include two hydrophobic proteins, represented in enteropathogenic Escherichia coli (EPEC) by EspB and EspD, which are thought to interact and f...

Enteropathogenic Escherichia coli, Samonella, Shigella and Yersinia: cellular aspects of host-bacteria interactions in enteric diseases

A successful infection of the human intestine by enteropathogenic bacteria depends on the ability of bacteria to attach and colonize the intestinal epithelium and, in some cases, to invade the host cell, survive intracellularly and disseminate from cell to cell. To accomplish these processes bacteria have evolved an arsenal of molecules that are mostly secreted by dedicated type III secretion s...
