A glycolipid that specifically binds shigella toxin was isolated from both HeLa cells and rabbit jejunal mucosa and identified as globotriaosylceramide (Gb3) by its identical mobility on HPTLC to(More)
Infection with Escherichia coli O157:H7 can lead to hemolytic uremic syndrome (HUS) in some children. Epidemiologic data suggest that Shiga toxin (Stx) 2-producing strains are more frequently(More)
We reported previously that mutation of the chromosomal gene eaeA from enterohemorrhagic Escherichia coli (EHEC) serotype O157:H7 prevented bacterial attachment in vivo. Attachment was restored when(More)
A simple purification scheme for shigella cytotoxin was devised, resulting in high yields (approximately 50%) and a 1,300-fold increase in specific activity compared with the initial crude bacterial(More)
Shiga toxin from Shigella dysenteriae 60R was purified to homogeneity by a novel one-step receptor analog affinity chromatography method. The method was based on the binding affinity of Shiga toxin(More)
