Escherichia /ˌɛʃəˈrɪkiə/ is a genus of Gram-negative, non-spore forming, facultatively anaerobic, rod-shaped bacteria from the family Enterobacteriaceae.^[1] In those species which are inhabitants of the gastrointestinal tracts of warm-blooded animals, Escherichia species provide a portion of the microbially derived vitamin K for their host. A number of the species of Escherichia are pathogenic.^[2] The genus is named after Theodor Escherich, the discoverer of Escherichia coli.

Pathogenesis

While many Escherichia are commensal gut flora, particular strains of some species are human pathogens,^[3] and are known as the most common cause of urinary tract infections,^[4] significant sources of gastrointestinal disease, ranging from simple diarrhea to dysentery-like conditions,^[1] as well as a wide range of other pathogenic states.^[5] While E. coli is responsible for the vast majority of Escherichia-related pathogenesis, other members of the genus have also been implicated in human disease.^[6]^[7]

Human transferrin receptor, referred as hTfR1, is ubiquitously expressed at low levels in most normal human tissues; however, the expression level of hTfR1 at the blood-brain barrier (BBB) and in tumor tissues is relatively higher. hTfR1 is a type II homodimeric transmembrane protein.
