BACKGROUND AND OBJECTIVE Photobacterium damselae subsp. damselae is a marine pathogenic bacterium which causes disease in marine animals and human. This bacterium mostly found in coastal shallow seawater. So, the aim of this study was isolation and characterization of Photobacterium damselae subsp. damselae from edible fish of Persian Gulf, Bandar Abbas. MATERIAL AND METHODS Totally 100 fish ...

Bacteria, gamma-subclass of Proteobacteria, Vibrio-Photobacterium, Vibrio vulnificus, Vibrio cholerae-Vibrio mimicus, and Vibrio cincinnatiensis in water samples collected from the Choptank River in Chesapeake Bay from 15 April to 16 December 1996 were enumerated using a fluorescent oligonucleotide direct-counting (FODC) procedure. FODC results obtained using a Bacteria taxon-specific probe ran...

Understanding of processes driving bacterial speciation requires examination of closely related, recently diversified lineages. To gain an insight into diversification of bacteria, we conducted comparative genomic analysis of two lineages of bioluminescent symbionts, Photobacterium leiognathi and 'P. mandapamensis'. The two lineages are evolutionary and ecologically closely related. Based on th...

We describe a case of a urinary tract infection with an unusual pathogen, Photobacterium damsela, in a pregnant female. This pathogen has been described as having a virulent life threatening nature, so a detailed history and prompt treatment is needed.

Histamine-producing bacteria (HPBs) have recently been identified from the marine environment. The identification and characterization of HPBs is important to developing effective mitigation strategies for scombrotoxin fish poisoning. We report here the draft genomes of seven histamine-producing and two non-histamine-producing marine Photobacterium strains.

The virulence regulatory protein ToxR of Vibrio cholerae is unique in that it contains a cytoplasmic DNA-binding-transcriptional activation domain, a transmembrane domain, and a periplasmic domain. Although ToxR and other transmembrane transcriptional activators have been discovered in other bacteria, little is known about their mechanism of activation. Utilizing degenerate oligonucleotides and...

During our search for new natural products from the marine environment, we discovered a wide range of cyclic peptides from a marine Photobacterium, closely related to P. halotolerans. The chemical fingerprint of the bacterium showed primarily non-ribosomal peptide synthetase (NRPS)-like compounds, including the known pyrrothine antibiotic holomycin and a wide range of peptides, from diketopiper...

ipa-43d is a hypothetical gene identified by the Bacillus subtilis genome project (Mol. Microbiol. 10, 371-384 1993; Nature 390, 249-256 1997). The ipa-43d protein overexpressed in E. coli was purified to homogeneity and its properties were analyzed biochemically. The ipa-43d protein was found to be tightly associated with FMN and to be capable of reducing both nitrofurazone and FMN effectively...

Rod-shaped structures have been observed in cells of Pseudomonas, Photobacterium, Proteus, and Saprospira by use of the negative-contrast stain. These structures, referred to as rhapidosomes, appear to be normal components of these cells. Other bacteria including Escherichia, Salmonella, Shigella, Klebsiella, Micrococcus, Bacillus, Mycobacterium, Rhodospirillum, and Hydrogenomonas genera failed...
