List of strains of Escherichia coli

Strains

Innocuous:

• K-12 is from a stool sample and does not seem to be pathogenic.

Laboratory:

• E. coli K-12, one of two main laboratory strains (innocuous)
• Clifton's original K-12 and the true "wild type", which is F+ λ+ O16. Still available as ATCC 10798.
• MG1655 "wild type", F- λ-
• DH1
• DH5α
• DH10b
• W3110 "wild type", F- λ-
• Dam dcm strain
• E. coli B, the other of the two main lab strains from which all lab substrains originate
• E. coli REL606
• E. coli BL21
• E. coli BL21(DE3)
• E. coli BL21-AI
• HB101, a hybrid between B and K-12 through recombination

Pathogenic:

• Escherichia coli NC101, a single isolate that acts as an AIEC (see below) in mice with serotype O2:H6/41

Groups of strains

Pathogenic:

• Enterotoxigenic E. coli (ETEC)
• Enteropathogenic E. coli (EPEC)
• Enteroinvasive E. coli (EIEC)
• Shigatoxigenic and verotoxigenic Escherichia coli (STEC/VTEC), which includes:
• Enterohemorrhagic E. coli
• Hemolytic uremic syndrome–associated enterohemorrhagic E. coli (HUSEC)
• (a group of several strains, albeit natural O157:H7 do share a common ancestor)
• 2006 North American E. coli outbreak
• Escherichia coli O121
• And technically: Shigella
• Shigella flexneri
• Shigella dysenteriae
• Shigella boydii
• Shigella sonnei
• Enteroaggregative E. coli (EAEC)
• Uropathogenic E. coli (UPEC)
• Escherichia coli K1 (a serogroup), meningitis
• Adherent-invasive Escherichia coli (AIEC), morbus Crohn
