A novel mesophilic bacterium, strain SS33, was isolated from a deep-sea hydrothermal vent chimney at Suiyo Seamount, Izu-Bonin Arc, Western Pacific Ocean. The cells of strain SS33 were motile short rods with a single polar flagellum. The growth of strain SS33 was observed at the temperature range between 33 and 55 °C (optimum growth at 45 °C), at the pH range between 5.

A molecular network reconstructed on the basis of nucleotide sequences of four phylogenetic maker protein genes revealed that the strains FE4, FE10, and LA51 were closely related to Pseudoalteromonas shioyasakiensis, Vibrio lentus, and Marinobacter similis, respectively. Average nucleotide identity (ANI) comparisons against phylogenetically related species to FE4, FE10, and LA51 demonstrated that each newly described strain could not be identified as any previously described species within each genus showing < 95% ANI: 91.

Cells of ISO32 were rods, being motile by means of a single polar flagellum. The isolate grew at a temperature range between 30 and 55 °C (optimum, 43 °C), at a pH range between 5.

Bacteriophages can be effectively used to reduce the incidence of foodborne pathogens. The host recognition systems of phages are highly specific, with the host range of a common phage being limited to the species or strain level.

View Article and Find Full Text PDFHistamine (scombroid) poisoning is a foodborne illness caused by ingestion of histamine-contaminated seafood; therefore, inhibition of the growth of histamine-producing bacteria is key for it prevention. Infection of pathogenic bacteria by bacteriophages (phages) is being developed to prevent multiple foodborne illnesses. Here, we describe the inhibitory effect of a phage mixture on growth and histamine accumulation of Morganella morganii subsp.

Morganella morganii has been identified as a causative agent of opportunistic infections and histamine poisoning. Bacteriophage is a virus and has recently been considered an alternative agent to antibiotics for the control of bacteria that have developed antibiotic resistance. In this study, a novel M.
