Escherichia /ˌɛʃəˈrɪkiə/ is a genus of Gram-negative non-spore forming facultatively anaerobic rod-shaped bacteria from the family Enterobacteriaceae. 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. The genus is named after Theodor Escherich the discoverer of Escherichia coli.
