title: Capnophilic Enterobacteriaceae.
abstract: Bacteria use bicarbonate as substrate for crucial metabolic reactions. We report the first case of bacteremia by capnophilic E. coli without the YadF gene (also known as CynT2 or Can2) that needs high concentrations of CO2to non-enzymatically produce bicarbonate. This lack may also apply to previously reported capnophilic Enterobacteriaceae.
