Improved Detection Methods for Selected Vibrio Species in the Marine Aquatic Environment
<p><em>Vibrio vulnificus</em>, <em>Vibrio cholerae</em>, and <em>Vibrio parahaemolyticus</em> are the three most commonly encountered human pathogens in the <em>Vibrio</em> genus. They are frequent agents of foodborne illness contracted from seafood. The work presented here focuses on three aspects …

Single and dual experimental infection of specific pathogen-free Litopenaeus vannamei shrimp with White Spot Syndrome Virus and Vibrio species
… especially white spot syndrome virus (WSSV) and vibriosis, have caused huge economic loss in shrimp culture in many countries. The availability of specific pathogen-free (SPF) is now facilitating the development of standardized protocols for pathogen challenge, as established recently for WSSV. …

The Genome of Vibrio orientalis : A Luminous Bacterium.
Vibrio orientalis was first isolated from the Yellow Sea in China and described as a luminous bacterium. Since the bacterium was named, a surprisingly sparse amount of information is available. In this study, the genome of V. orientalis was sequenced; the draft genome consists of five contigs. The …

Determinants Influencing Polar Flagellar Biosynthesis and Cell Division in Campylobacter jejuni
… and flagellar placement in some Pseudomonas and Vibrio species. Characterization of FlhF in C. jejuni was accomplished by creating point mutants in C-terminal GTPase domain of FlhF to decrease its GTPase activity. GTPase mutants, unlike mutants that lack FlhF, did not have a significant reduction …

Experimental studies of RctB- initiator of Vibrio cholerae chromosome II replication: genetic engineering, protein purification, and protein crystals
<p>Vibrio cholerae, a member of the Vibrionaceae family, is notorious as the causative agent of acute gastrointestinal disease known as cholera. Genetic information in members of the Vibrionaceae family is distributed between two chromosomes that are distinctively maintained. In V. cholerae, the …

Interactions between calanoid copepod hosts and their associated microbiota
… copepod Eurytemora affinis to two distinct Vibrio species, a free-living (V. ordalii 12B09) and a zooplankton specialist (V. sp. F10 9ZB36), and found that E. affinis distinctly responds to colonizing Vibrios. Finally, we probed how specifically and predictably bacterial communities assemble …

The Presence of Pathogenic Bacteria in Recirculating Aquaculture System Biofilms and their Response to Various Sanitizers
… pathogens were Bacillus cereus, the Shigella species and the Vibrio species. The major piscine pathogens of concern were Photobacterium damsela, the Vibrio species, and Aeromonas hydrophila. The most significant variation in biofilm pathogens was observed between facilities and not …

Symbiotic Associations and Pathogenic Potential of Vibrios In the North Inlet Estuary
… marsh sediment. Bacteria belonging to the genus Vibrio are flagellated gram negative rods or curved rods common throughout marine systems. Vibrios inhabit a range of niches within the water column, attached to sediment particles and in symbiotic associations with marine animals and plants. Most …

Properties of NadV / NatV Proteins in a Pyridine Nucleotide (NAD+) Scavenging System Encoded by Vibriophage KVP40
… KVP40 is a T4-type phage that infects Vibrio species. In the phage 245 kbp dsDNA genome, a set of bacterial-like genes, nadV, natV, pnuC, nadR and sir2 are predicted to be involved in the synthesis and recycling of nicotinamide adenine dinucleotide (NAD+). Comparison with proteins of …

Ecology and population structure of Vibrionaceae in the coastal ocean
… populations of the gamma-proteobacterial family, Vibrionaceae, are ecologically specialized by investigating the distribution across a wide range of environmental categories, such as marine invertebrates or particles in the water column. Additionally, it seeks to determine whether in situ …

The role of enteric bacteria in the Abalone, Haliotis Midae
… tests. The common genera identified were Vibrio, Alcaligenes, Flavobacteria, Pseudomonas and Aeromonas. The bacterial communities in each gut region varied, suggesting that both resident and transient bacterial populations are present in H. midae. Alcaligenes occurred mainly in the crop, …

Functional analysis of the role of alternative sigma factors in Vibrio parahaemolyticus host pathogen interactions
Vibrio parahaemolyticus, a ubiquitous Gram-negative marine bacterium, is the leading cause of bacterial seafood borne gastroenteritis in humans. This organism must adapt to both host and marine environmental stresses. One mechanism bacteria employ to respond to rapid environmental changes is the …

Responses of an Environmental Gram-negative Bacterium to Pollutant Stress
… to classify the pseudomonads and related species at the genetic level. In order to see to what extent the pseudomonads and related species responded to heat shock, cells were initially subjected to temperature upshift from 28 to 37 deegree centegrade then disrupted by sonication or cells …
