[The amine-forming ability of Aeromonas spp].
Motile Aeromonas (A.) species are considered international more and more as potential food poisoning organisms. Their ability to produce biogenic amines, products of metabolism, which in case can cause a disease, was only searched insufficiently till now. 50 strains of the species A.hydrophila, A.sobria, A.caviae and the non-motile species A.salmonicida were included in the tests for amine producing potency. Qualitative investigations to the formation of histamine, tryptamine, and tyramine were ensued by the help of thin layer chromatography. Quantitative investigations were only done in respect of the production of tyramine, which had been proved qualitatively in several strains, while histamine and tryptamine were not produced. Concentrations of tyramine with foodhygienic relevance were found out partially.
