Comparative analysis and distribution of pP9014, a novel drug resistance IncP-1 plasmid from Photobacterium damselae subsp. piscicida.

Photobacterium damselae subsp. piscicida, a causative agent of pseudotuberculosis, often harbours resistance plasmids (R plasmids) that facilitate horizontal gene transfer of drug resistance genes. R plasmid pP9014 was isolated from P.

Cloning and sequencing of the histidine decarboxylase gene from Photobacterium phosphoreum and its functional expression in Escherichia coli.

The major causative agent of scombroid poisoning is histamine formed by bacterial decarboxylation of histidine. We reported previously that histamine was exclusively formed by the psychrotrophic halophilic bacteria Photobacterium phosphoreum in scombroid fish during storage at or below 10 degrees C. Moreover, histamine-forming ability was affected by two histidine decarboxylases (HDCs): constitutive and inducible enzymes.

Activity of two histidine decarboxylases from Photobacterium phosphoreum at different temperatures, pHs, and NaCl concentrations.

Cloning and nucleotide sequence analysis of the chloramphenicol resistance gene on conjugative R plasmids from the fish pathogen Photobacterium damselae subsp. piscicida.

Transferable resistance to various drugs was investigated in Photobacterium damselae subsp. piscicida from Japan. Drug resistances were transferred via plasmids of 100, 50, and 40 kb.
