Quantification des bactéries histaminogènes et maîtrise de la formation d'histamine dans les produits marins par biopréservation ArchiMer
Podeur, Gaetan.
Histamine-producing bacteria were isolated from naturally contaminated seafood, some of responsible for histamine-poisoning. At the same time, lactic acid bacteria were isolated on the same products and clustered according to their inhibitory activity against 4 histamine-producing species. Most of the strains were identified as Lactobacillus fuchuensis or Lactobacillus sakei. Twelve lactic acid bacteria were selected for challenge-test on canned, cooked or smoked tuna. Challenge-test combined with sensory analysis performed on cooked vacuum-packed tuna against Morganella psychrotolerans and Morganella morganii, demonstrated an important inhibitory effect on growth and production of histamine with L. sakei CNCM I-4707. Bacterial count was reduced by 3 to 5...

Development of a real-time PCR method coupled with a selective pre-enrichment step for quantification of Morganella morganii and Morganella psychrotolerans in fish products ArchiMer
Podeur, Gaetan; Dalgaard, Paw; Leroi, Francoise; Prevost, Herve; Ernborg, Jette; Martinussen, Jan; Hansen, Lars Hestbjerg; Filet, Marie-france.
Histamine fish poisoning is common and due to toxic concentrations of histamine often produced by Gram-negative bacteria in fin-fish products with a high content of the free amino acid histidine. The genus Morganella includes two species previously reported to cause incidents of histamine fish poisoning. Morganella morganii and Morganella psychrotolerans are both strong producer of histamine. However, little is known about the occurrence and critical stages for fish contamination with these bacteria. To elucidate contamination routes of Morganella, specific real-time quantitative PCR (RTi qPCR) methods for quantification of M. morganii and M. psychrotolerans have been developed. Selective primers amplified a 110 bp region of the vasD gene for M....
