Investigating the amine formation from amino-acids by the strain of Esch. Coli communior isolated by Hirata, the authors intended to elucidate the chemical properties of the histamine-like substance contained in the ileac intestine experimentally induced in rabbits. The amino-acids employed in the present experiments are histidine and arginine to investigate the formations of histamine and putrescine respectively. The following is the conclusion thus obtained.
The strains of Esch. Coli communior isolated from the ileac intestine experimentally induced in rabbits were found to form histamine and putrescine from histidine and arginine respectively.
