Escherichia coli IPT245

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

Escherichia coli BL21 is a laboratory expression host strain widely used in molecular biology for recombinant protein production; it is not a probiotic organism and is not used in human health supplementation.

Escherichia coli MG1655 is a well-characterized, non-pathogenic K-12 laboratory reference strain used extensively as a model organism in microbiology and biotechnology research.

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