Escherichia Coli
Reports outline Escherichia coli study results from Osaka University
March 17th, 2009
According to a study from Suita, Japan, "Enterohemorrhagic Escherichia coli (EHEC) delivers virulence factors into host cells through the type III secretion system (T3SS) to exert the bacterial pathogenicity. EHEC encodes more than 20 type III secretion system-delivered families of effectors that have different functions at different infectious stages and enable a successful infection." "One of them, EspL2, is encoded on the SpLE3 phage-like element in EHEC O157:H7 Sakai and is well conserved among various EHEC strains. Here we show that, after delivery into host cells, EspL2 accumulated under adherent bacteria, as did polymerized F-actin. EspL2-expressing EHEC formed...
