Escherichia coli (E. coli) K-12 is rifampicin-resistant
Bonnet et al. 2014 Clinical cancer research 20(4): 859-67

Escherichia coli (E. coli) K-12 belongs to the dopamine-producing strains
Shishov et al. 2009 Prikl Biokhim Mikrobiol. 45(5): 550-4

Enzyme systems similar to those of animals are probably involved in the biosynthesis and degradation of monoamine neuromodulators in bacterial cells.
Shishov et al. 2009 Prikl Biokhim Mikrobiol. 45(5): 550-4

The culture fluid of E. coli contains micromolar concentrations of DOPA and nanomolar concentrations of serotonin, dopamine, and noradrenaline during the late growth phase. These concentrations are sufficient for binding to mammalian receptors
