Title: Development of a histidine decarboxylase medium and its application to detect other amino acid decarboxylases
Abstract: A liquid medium is described which can be used to detect histidine decarboxylase activity in bacterial pure cultures within 24 h. It can also be used to detect the presence of histamine-producing Enterobacteriaceae in mixed cultures, e.g. in environmental swab specimens by colour change within 48 h. A limited number of tests with tuna fish meat show that this medium may also be used for a semi-quantitative detection of histamine producers, for example by utilizing the MPN technique. Comparative examinations with Møller's decarboxylase medium using 122 Enterobacteriaceae strains demonstrated that the medium can also be used to prove the decarboxylation of lysine, ornithine and arginine. The advantage of the new medium is the faster indication of positive reactions.
