Escherichia coli ATCC 8739 is a non-pathogenic, biosafety level 1 laboratory reference strain used extensively as a negative control or challenge organism in antimicrobial and microbiological assays.

Escherichia coli K12 is a non-pathogenic laboratory reference strain that has been central to molecular biology and genetics research since the mid-20th century.

Escherichia coli is a highly diverse bacterial species found naturally in the human gut, where most strains are commensal, meaning they coexist with their host without causing harm.

Escherichia coli ATCC 25922 is a well-characterized reference strain used as a quality control organism in antimicrobial susceptibility testing and microbiological laboratory work; it is not a probiotic strain.

Escherichia coli K-12 MG1655 is the canonical laboratory reference strain of E.

Escherichia coli AY1 is a designated E. coli strain with no strain-specific published evidence available in the current literature index.
