BACKGROUND Enterohemorrhagic Escherichia coli (EHEC) O157:H7, a food and waterborne pathogen, can be classified into nine phylogenetically distinct lineages, as determined by single nucleotide polymorphism genotyping. One lineage (clade 8) was found to be associated with hemolytic uremic syndrome (HUS), which can lead to kidney failure and death in some(More)
BACKGROUND Global patterns of gene expression of Escherichia coli K-12 during growth transitions have been deeply investigated, however, comparable studies of E. coli O157:H7 have not been explored, particularly with respect to factors regulating virulence genes and genomic islands specific to this pathogen. To examine the impact of growth phase on the(More)
In order to provide a portable and accurate typing system for the unambiguous characterization of pathogenic Escherichia coli isolates to the scientific community, we have constructed an online database for MultiLocus Sequence Typing of pathogenic E. coli (EcMLST) using current internet and open source technology. The system consists of an XML specification(More)
Many poisoned patients may only require a period of observation after their exposure. There are limited data describing the use of observation units for managing poisoned adult and pediatric patients. We performed a retrospective review of all patients reported to the ToxIC Case Registry between January 1, 2012 and December 31, 2013. Eligible patients(More)
