An ENTEROTOXIN from VIBRIO CHOLERAE. It consists of two major protomers, the heavy (H) or A subunit and the B protomer which consists of 5 light (L) or B subunits. The catalytic A subunit is proteolytically cleaved into fragments A1 and A2. The A1 fragment is a MONO(ADP-RIBOSE) TRANSFERASE. The B protomer binds cholera toxin to intestinal epithelial cells, and facilitates the uptake of the A1 fragment. The A1 catalyzed transfer of ADP-RIBOSE to the alpha subunits of heterotrimeric G PROTEINS activates the production of CYCLIC AMP. Increased levels of cyclic AMP are thought to modulate release of fluid and electrolytes from intestinal crypt cells.

Reassessment of the taxonomic position of Vibrio iliopiscarius (Onarheim et al. 1994) and proposal for Photobacterium iliopiscarium comb. nov. (1/1761)

The phylogenetic position of Vibrio iliopiscarius was inferred by the maximum-likelihood, maximum-parsimony and neighbour-joining methods on the basis of almost complete 16S rRNA gene sequences. The results showed that this species falls into the same cluster as Photobacterium species and is clearly distinct from other Vibrio species. Its nearest phylogenetic neighbour is Photobacterium phosphoreum. From these results, it is concluded that V. iliopiscarius should be reclassified as Photobacterium iliopiscarium comb. nov., the type strain of which is PS1T (= ATCC 51760T).  (+info)

Inhibition of vibrio anguillarum by Pseudomonas fluorescens AH2, a possible probiotic treatment of fish. (2/1761)

To study the possible use of probiotics in fish farming, we evaluated the in vitro and in vivo antagonism of antibacterial strain Pseudomonas fluorescens strain AH2 against the fish-pathogenic bacterium Vibrio anguillarum. As iron is important in virulence and bacterial interactions, the effect of P. fluorescens AH2 was studied under iron-rich and iron-limited conditions. Sterile-filtered culture supernatants from iron-limited P. fluorescens AH2 inhibited the growth of V. anguillarum, whereas sterile-filtered supernatants from iron-replete cultures of P. fluorescens AH2 did not. P. fluorescens AH2 inhibited the growth of V. anguillarum during coculture, independently of the iron concentration, when the initial count of the antagonist was 100 to 1, 000 times greater that of the fish pathogen. These in vitro results were successfully repeated in vivo. A probiotic effect in vivo was tested by exposing rainbow trout (Oncorynchus mykiss Walbaum) to P. fluorescens AH2 at a density of 10(5) CFU/ml for 5 days before a challenge with V. anguillarum at 10(4) to 10(5) CFU/ml for 1 h. Some fish were also exposed to P. fluorescens AH2 at 10(7) CFU/ml during the 1-h infection. The combined probiotic treatment resulted in a 46% reduction of calculated accumulated mortality; accumulated mortality was 25% after 7 days at 12 degrees C in the probiotic-treated fish, whereas mortality was 47% in fish not treated with the probiont.  (+info)

Effects of salinity and temperature on long-term survival of the eel pathogen Vibrio vulnificus biotype 2 (serovar E). (3/1761)

Vibrio vulnificus biotype 2 (serovar E) is a primary eel pathogen. In this study, we performed long-term survival experiments to investigate whether the aquatic ecosystem can be a reservoir for this bacterium. We have used microcosms containing water of different salinities (ranging from 0.3 to 3.8%) maintained at three temperatures (12, 25, and 30 degrees C). Temperature and salinity significantly affected long-term survival: (i) the optimal salinity for survival was 1.5%; (ii) lower salinities reduced survival, although they were nonlethal; and (ii) the optimal temperature for survival was dependent on the salinity (25 degrees C for microcosms at 0.3 and 0.5% and 12 degrees C for microcosms at 1.5 to 3.8%). In the absence of salts, culturability dropped to zero in a few days, without evidence of cellular lysis. Under optimal conditions of salinity and temperature, the bacterium was able to survive in the free-living form for at least 3 years. The presence of a capsule on the bacterial cell seemed to confer an advantage, since the long-term survival rate of opaque variants was significantly higher than that of translucent ones. Long-term-starved cells maintained their infectivity for eels (as determined by both intraperitoneal and immersion challenges) and mice. Examination under the microscope showed that (i) the capsule was maintained, (ii) the cell size decreased, (iii) the rod shape changed to coccuslike along the time of starvation, and (iv) membrane vesicles and extracellular material were occasionally produced. In conclusion, V. vulnificus biotype 2 follows a survival strategy similar to that of biotype 1 of this species in response to starvation conditions in water. Moreover, the aquatic ecosystem is one of its reservoirs.  (+info)

Randomly amplified polymorphic DNA analysis of clinical and environmental isolates of Vibrio vulnificus and other vibrio species. (4/1761)

Vibrio vulnificus is an estuarine bacterium that is capable of causing a rapidly fatal infection in humans. A randomly amplified polymorphic DNA (RAPD) PCR protocol was developed for use in detecting V. vulnificus, as well as other members of the genus Vibrio. The resulting RAPD profiles were analyzed by using RFLPScan software. This RAPD method clearly differentiated between members of the genus Vibrio and between isolates of V. vulnificus. Each V. vulnificus strain produced a unique band pattern, indicating that the members of this species are genetically quite heterogeneous. All of the vibrios were found to have amplification products whose sizes were within four common molecular weight ranges, while the V. vulnificus strains had an additional two molecular weight range bands in common. All of the V. vulnificus strains isolated from clinical specimens produced an additional band that was only occasionally found in environmental strains; this suggests that, as is the case with the Kanagawa hemolysin of Vibrio parahaemolyticus, the presence of this band may be correlated with the ability of a strain to produce an infection in humans. In addition, band pattern differences were observed between encapsulated and nonencapsulated isogenic morphotypes of the same strain of V. vulnificus.  (+info)

Arbitrarily primed PCR to type Vibrio spp. pathogenic for shrimp. (5/1761)

A molecular typing study on Vibrio strains implicated in shrimp disease outbreaks in New Caledonia and Japan was conducted by using AP-PCR (arbitrarily primed PCR). It allowed rapid identification of isolates at the genospecies level and studies of infraspecific population structures of epidemiological interest. Clusters identified within the species Vibrio penaeicida were related to their area of origin, allowing discrimination between Japanese and New Caledonian isolates, as well as between those from two different bays in New Caledonia separated by only 50 km. Other subclusters of New Caledonian V. penaeicida isolates could be identified, but it was not possible to link those differences to accurate epidemiological features. This contribution of AP-PCR to the study of vibriosis in penaeid shrimps demonstrates its high discriminating power and the relevance of the epidemiological information provided. This approach would contribute to better knowledge of the ecology of Vibrio spp. and their implication in shrimp disease in aquaculture.  (+info)

Isolation of Vibrio vulnificus serovar E from aquatic habitats in Taiwan. (6/1761)

The existence of strains of Vibrio vulnificus serovar E that are avirulent for eels is reported in this work. These isolates were recovered from water and oysters and differed from eel virulent strains in (i) fermentation and utilization of mannitol, (ii) ribotyping after HindIII digestion, and (iii) susceptibility to eel serum. Lipopolysaccharide of these strains lacked the highest molecular weight immunoreactive bands, which are probably involved in serum resistance.  (+info)

Mechanosensitive channel functions to alleviate the cell lysis of marine bacterium, Vibrio alginolyticus, by osmotic downshock. (7/1761)

The mechanosensitive channel with large conductance of Escherichia coli is the first to be cloned among stretch-activated channels. Although its activity was characterized by a patch clamp method, a physiological role of the channel has not been proved. The marine bacterium, Vibrio alginolyticus, is sensitive to osmotic stress and cell lysis occurs under osmotic downshock. We introduced an mscL gene into Vibrio alginolyticus, and the mechanosensitive channel with large conductance functions was found to alleviate cell lysis by osmotic downshock. This is the first report to show a physiological role of the mechanosensitive channel with large conductance.  (+info)

The polar flagellar motor of Vibrio cholerae is driven by an Na+ motive force. (8/1761)

Vibrio cholerae is a highly motile bacterium which possesses a single polar flagellum as a locomotion organelle. Motility is thought to be an important factor for the virulence of V. cholerae. The genome sequencing project of this organism is in progress, and the genes that are highly homologous to the essential genes of the Na+-driven polar flagellar motor of Vibrio alginolyticus were found in the genome database of V. cholerae. The energy source of its flagellar motor was investigated. We examined the Na+ dependence and the sensitivity to the Na+ motor-specific inhibitor of the motility of the V. cholerae strains and present the evidence that the polar flagellar motor of V. cholerae is driven by an Na+ motive force.  (+info)

BioAssay record AID 406643 submitted by ChEMBL: Antimicrobial activity against Vibrio anguillarum serotype O2b 04/09/367-5043 isolate containing gyrA position 83 Ser-Ile substitution mutation from Atlantic cod at 30 ug by disc diffusion assay.
Vibrio costicola grown in the presence of different NaCl concentrations contains cell-associated Na+ and K+ ions whose sum is equal to or greater than the external Na+ concentration. In the presence of 0.5 M NaCl, virtually no in vitro protein is synthesized in extracts of cells grown in 1.0 M NaCl. However, we report here that active in vitro protein synthesis occurred in 0.6 M or higher concentrations of Na2SO4, sodium formate, sodium acetate, sodium aspartate, or sodium glutamate, whereas 0.6 M NaF, NaCl, or NaBr completely inhibited protein synthesis as measured by polyuridylic acid-directed incorporation of [14C]phenylalanine. Sodium glutamate, sodium aspartate, and betaine (0.3 M) counteracted the inhibitory action of 0.6 M NaCl. The cell-associated Cl- concentration was 0.22 mol/kg in cells grown in 1.0 M NaCl. Of this, the free intracellular Cl- concentration was only 0.02 mol/kg. Cells contained 0.11 mol of glutamate per kg and small concentrations of other amino acids. All of the ...
In developing countries, the fraction of treated wastewater effluents being discharged into watersheds have increased over the period of time, which have led to the deteriorations of the qualities of major rivers in developing nations. Consequently, high densities of disease causing bacteria in the watersheds are regularly reported including incidences of emerging Vibrio fluvialis. Vibrio fluvialis infection remains among those infectious diseases posing a potentially serious threat to public health. This paper addresses the epidemiology of this pathogen; pathogenesis of its disease; and its clinical manifestations in humans.
Vibrio strains isolated from plankton, sediments, and seawater in two coastal areas south of Valencia, Spain, were genotypically and phenotypically different from other Vibrio species. The guanine-plus-cytosyine content of the strains was 43 mol%. Deoxyribonucleic acid-deoxyribonucleic acid hybridization studies revealed that the strains were genetically homogeneous and exhibited very low levels of genetic relatedness to Vibrio parahaemolyticus ATCC 17802T(T = type strain) (0%), Vibrio harveyi NCMB 1280T(11%), Vibrio vulnificus NCMB 2046T(7%), Vibrio nereis NCMB 1897T(0%), Vibrio natriengens NCMB (9%), and Vibrio splendidus NCMB 1T(0%). Strain CECT 621 of the Colección Española de Cultivos Tipo was designated the type strain of the proposed new species Vibrio mediterranei.
16S rRNA from seven different Vibrio anguillarum strains was partially sequenced and compared. From this sequence information we could design a 25-base-long oligonucleotide and use it as a specific probe for identification of V. anguillarum. This was determined by RNA-DNA colony hybridization and slot-blot hybridization. Strong, specific hybridization to the probe was observed for all V. anguillarum strains tested. Furthermore, no cross-hybridization could be seen against five other bacterial species. The detection limit was 5 x 10(3) bacteria per ml. It was even possible to detect V. anguillarum, by slot-blot hybridization, directly in a homogenized kidney from a fish that had died of vibriosis. The partial sequence information revealed small but significant differences between strains of the same species. These sequence differences are sufficiently significant to allow serotyping on the RNA level. Comparing strains of different serotypes revealed a 10-base and an 11-base difference in V. ...
Numerous prevalence studies of Vibrio spp. infection in fish have been extensively reported worldwide, including Malaysia. Unfortunately, information on the prevalence of Vibrio spp. in groupers (Epinephelus spp.) is limited. In this study, groupers obtained from nine farms located at different geographical regions in Malaysia were sampled for the presence of pathogenic Vibrio spp. and their susceptibility profiles against seven antibiotics. Out of 270 grouper samples, 195 (72%) were detected with the presence of Vibrio spp. Vibrio communis showed highest prevalence in grouper (28%), followed by V. parahaemolyticus (25%), V. alginolyticus (19%), V. vulnificus (14%), V. rotiferianus (3%), Vibrio sp. (3%), V. campbellii (2%), V. mytili (2%), V. furnissii (2%), V. harveyi (1%), V. tubiashii (1%), V. fluvialis (0.3%) and V. diabolicus (0.3%). Assessment on the antibiotic susceptibility profiles of the Vibrio spp. revealed that majority of the isolates were susceptible to tetracycline, streptomycin,
Quorum sensing (QS) is a process enabling a bacterial population to communicate via small molecules called autoinducers (Als). This intercellular communication process allows single cells to synchronize their behavior within a population. The marine bacterium Vibrio harveyi ATCC BAA-1116 channels the information of three Al signals into one QS cascade. Three receptors perceive these Als, the hybrid histidine kinases LuxN, Lux(P)Q and CqsS, to transduce the information to the histidine phosphotransfer (HPt) protein LuxU via phosphorelay, and finally to the response regulator LuxO. Hence, the level of phosphorylated LuxO depends on the Al concentrations. The phosphorylated LuxO (P-LuxO) controls the expression of small regulatory RNAs (sRNAs), which together with the RNA chaperon Hfq, destabilize the transcript of the master regulator luxR. LuxR is responsible for the induction and repression of several genes (e.g., for bioluminescence, exoprotease and siderophore production). In vivo studies with ...
The enzymes for luminescence in Vibrio fischeri are induced by the accumulation of a species-specific metabolite (autoinducer) in the culture medium. Tritium-labeled autoinducer was used to study the mechanism of autoinduction. When 3H-autoinducer was added to suspensions of V. fischeri or Escherichia coli, cellular concentrations equaled external concentrations. For V. fischeri, equilibration of 3H-autoinducer was rapid (within 20 s), and greater than 90% of the cellular tritium remained in unmodified autoinducer. When V. fischeri or E. coli cells containing 3H-autoinducer were transferred to autoinducer-free buffer, 85 to 99.5% of the radiotracer escaped from the cells, depending on the strain. Concentrations of autoinducer as low as 10 nM, which is equivalent to 1 or 2 molecules per cell, were sufficient for induction, and the maximal response to autoinducer occurred at about 200 nM. If external autoinducer concentrations were decreased to below 10 nM after induction had commenced, the ...

Scale drop and muscle necrosis disease with high mortality widely occurred recently in the hybrid grouper (Epinephelus fuscoguttatus ♀ × E. lanceolatus ♂), a crucial cultured marine fish species in China. In this study, 30 Harveyi clade isolates of 27 Vibrio harveyi strains were isolated from diseased hybrid groupers in the south‐east and north‐east coastal areas of China. A total of 22 V. harveyi strains were determined to be pathogenic, and most challenged fish died within 2 days of infection; surviving individuals exhibited scale drop and deep dermal lesions as naturally diseased fish. Although five typical virulence genes, including luxR, toxRVₕ, chiA, serine protease and vhh widely existed in V. harveyi, no obvious correlation was established between virulent strains and virulence genes harboured in them. Furthermore, multiple antibiotic resistance was widely exhibited in Harveyi clade strains, particularly for penicillins, polypeptides, lincomycins, acetylspiramycin, ...
Proteorhodopsin (PR), a ubiquitous membrane photoprotein in marine environments, acts as a light-driven proton pump and can provide energy for bacterial cellular metabolism. However, knowledge of factors that regulate PR gene expression in different bacteria remains strongly limited. Here, experiments with Vibrio sp. AND4 showed that PR phototrophy promoted survival only in cells from stationary phase and not in actively growing cells. PR gene expression was tightly regulated, with very low values in exponential phase, a pronounced peak at the exponential/stationary phase intersection, and a marked decline in stationary phase. Thus, PR gene expression at the entry into stationary phase preceded, and could therefore largely explain, the stationary phase light-induced survival response in AND4. Further experiments revealed nutrient limitation, not light exposure, regulated this differential PR expression. Screening of available marine vibrios showed that the PR gene, and thus the potential for PR ...

Autoinducer-2 (AI-2), a furanosyl borate diester, is a member of a family of signaling molecules used in quorum sensing. AI-2 is one of only a few known biomolecules incorporating boron. First identified in the marine bacterium Vibrio harveyi, AI-2 is produced and recognized by many Gram-negative and Gram-positive bacteria. AI-2 arises by the reaction of 1-deoxy-3-dehydro-D-ribulose, which is produced enzymatically, with boric acid and is recognized by the two-component sensor kinase LuxPQ in Vibrionaceae. AI-2 is actively transported by the Lsr ABC-type transporter into the cell in Enterobacteriaceae and few other bacterial taxa (Pasteurella, Photorhabdus, Haemophilus, Bacillus), where it is phosphorylated by LsrK . Then, Phospho-AI-2 binds the transcriptional repressor protein, LsrR, which subsequently is released from the promoter/operator region of the lsr operon - and transcription of the lsr genes is initiated. AI-2 signalling is also regulated by glucose and cAMP/CRP via the lsr operon. ...

Quorum sensing systems serve as a means of census taking of conspecific and non-conspecific bacteria in the near vicinity. The acylated homoserine lactone (AHL) quorum sensing system has been proposed to be primarily an intra-specific communication system, while the AI-2 autoinducer signalling system is proposed to be an interspecific communication system. Here it is shown that AI-2-like signalling in two marine Vibrio species, Vibrio vulnificus and Vibrio angustum S14, induces the core response phenotypes of starvation adaptation and stress resistance, and that a signal antagonist can competitively inhibit these phenotypes. Furthermore, the signals produced by a range of Vibrio species have the ability to induce these phenotypes in V. vulnificus and V. angustum S14, indicating that, at least in Vibrio species, AI-2-like signalling systems function as interspecies communication systems capable of cross-talk and of regulating environmentally relevant phenotypes.

The genus Vibrio is a metabolically diverse group of facultative anaerobic bacteria, common in aquatic environments and marine hosts. The genus contains several species of importance to human health and aquaculture, including the causative agents of human cholera and fish vibriosis. Vibrios display a wide variety of known life histories, from opportunistic pathogens to long-standing symbionts with individual host species. Studying Vibrio ecology has been challenging as individual species often display a wide range of habitat preferences, and groups of vibrios can act as socially cohesive groups. Although strong associations with salinity, temperature and other environmental variables have been established, the degree of habitat or host specificity at both the individual and community levels is unknown. Here we use oligotyping analyses in combination with a large collection of existing Vibrio 16S ribosomal RNA (rRNA) gene sequence data to reveal patterns of Vibrio ecology across a wide range of ...
Vibrio taxonomy has been based on a polyphasic approach. In this study, we retrieve useful taxonomic information (i.e. data that can be used to distinguish different taxonomic levels, such as species and genera) from 32 genome sequences of different vibrio species. We use a variety of tools to explore the taxonomic relationship between the sequenced genomes, including Multilocus Sequence Analysis (MLSA), supertrees, Average Amino Acid Identity (AAI), genomic signatures, and Genome BLAST atlases. Our aim is to analyse the usefulness of these tools for species identification in vibrios. We have generated four new genome sequences of three Vibrio species, i.e., V. alginolyticus 40B, V. harveyi-like 1DA3, and V. mimicus strains VM573 and VM603, and present a broad analyses of these genomes along with other sequenced Vibrio species. The genome atlas and pangenome plots provide a tantalizing image of the genomic differences that occur between closely related sister species, e.g. V. cholerae and V. mimicus.
The genus Vibrio includes serious human pathogens, such as V. vulnificus (Vv) and V. cholerae (Vc). Some species infect shellfish, such as Vibrio nigripulchritudo (Vn), which is a shrimp pathogen. Vibrio species encode PecS, a member of the multiple antibiotic resistance regulator (MarR) family of transcription factors. PecS is encoded by the pecS gene and expression is auto regulatory. The pecS gene is divergently oriented to pecM, which encodes an efflux pump. Vibrio species feature frequent duplication of pecS-pecM genes, which may facilitate how these species adapt from being free living motile bacteria in water columns to colonizing host tissues as biofilms to evade distinct environmental pressures. Vibrio vulnificus, commonly associated with consumption of undercooked oyster encodes a single pecS-pecM gene pair. Vv PecS was shown to bind two sites within the pecS-pecM (iSM) intergenic region with Kd = 0.3 ± 0.1 nM, a binding that is attenuated by purine ligands xanthine and urate. A unique DNA
Home. Vibrios are Gram-negative bacteria found in aquatic environments. These bacteria show a wide range of niche specialization, from free-living forms to those attached to biotic and abiotic surfaces and from symbionts to pathogens. In addition to human pathogens such as V. cholerae, V. parahemolyticus and V. vulnificus, vibrios have been associated with disease in numerous aquatic organisms, including coral, shrimp and oysters, and infections due to these pathogens have profound environmental and economic consequences. Not surprisingly, the vibrio genus provides models for extremely diverse scientists, including those who study ecology, evolution, genome plasticity and maintenance, gene regulation, bacterial pathogenesis and host microbe interactions, bacterial social behavior and epidemiology. To foster interactions between these diverse communities, we invite all scientists who work on vibrios to participate at the next Vibrio conference at the Marine Biological Station of Roscoff in 2016. ...
The phosphoenolpyruvate (PEP)-dependent phosphotransferase system (PTS) is a major mechanism used by bacteria for uptake of carbohydrates, particularly hexoses, hexitols, and disaccharides, where the source of energy is from PEP. The PTS consists of two general components, enzyme I (EI) and histidine phosphocarrier protein (HPr), and of membrane-bound sugar specific permeases (enzymes II). Each enzyme II (EII) complex consists of one or two hydrophobic integral membrane domains (domains C and D) and two hydrophilic domains (domains A and B). EII complexes may exist as distinct proteins or as a single multidomain protein. The PTS catalyzes the uptake of carbohydrates and their conversion into their respective phosphoesters during transport. There are four successive phosphoryl transfers in the PTS. Initial autophosphorylation of EI, using PEP as a substrate, is followed by transfer of the phosphoryl group from EI to HPr. EIIA catalyzes the self-phosphoryl transfer from HPr after which the ...
Homologous recombination (HR) is essential for the accurate repair of DNA double-strand breaks (DSBs), potentially lethal lesions. HR takes place in the late S-G2 phase of the cell cycle and involves the generation of a single-stranded region of DNA, followed by strand invasion, formation of a Holliday junction, DNA synthesis using the intact strand as a template, branch migration and resolution. It is investigated that RecA/Rad51 family proteins play a central role. The breast cancer susceptibility protein Brca2 and the RecQ helicase BLM (Bloom syndrome mutated) are tumor suppressors that maintain genome integrity, at least in part, through HR ...
Vibrio harveyi is a bioluminescent bacterium and the organism in which quorum sensing was discovered. It was recently found that a class of molecules, cyclic dipeptides, may be a new kind of quorum sensing signal that may affect other species in the genus. The purpose of this study was to determine if V. harveyi produced one of these molecules, cyclo(Phe-Pro) or cFP, and the effects it has on bioluminescence, growth and gene expression. Electrospray Mass Spectrometry was used to detect cFP, and it was found. While growth and gene expression were not significantly affected by cFP, bioluminescence was slightly induced at low concentrations. It appears that V. harveyi does not produce cFP and it does not significantly affect the luminescence quorum sensing controlled genes, and is most likely not a true signal, in V. harveyi.

The membrane lipid composition of living cells generally adjusts to the prevailing environmental and physiological conditions. In this study, membrane activity and lipid composition of the Gram-negative bacterium Vibrio sp. DSM14379, grown aerobically in a peptone-yeast extract medium supplemented with 0.5, 1.76, 3, 5 or 10% (w/v) NaCl, was determined. The ability of the membrane to reduce a spin label was studied by EPR spectroscopy under different salt concentrations in cell suspensions labeled with TEMPON. For lipid composition studies, cells were harvested in a late exponential phase and lipids were extracted with chloroform-methanol-water, 1:2:0.8 (v/v). The lipid polar head group and acyl chain compositions were determined by thin-layer and gas-liquid chromatographies. 31P-NMR spectroscopy was used to study the phase behaviour of the cell lipid extracts with 20 wt.% water contents in a temperature range from −10 to 50 °C. The results indicate that the ability of the membrane to reduce ...

Sailors have long reported miraculous sightings of luminous, glowing seawater. Consider Captain Kingman s report, made in the dead of night in June, 1854, in the ocean south of Java, Indonesia. The whole appearance of the ocean was like a plain covered with snow, Kingman wrote. Ocean-going myth? It turns out that the stories are true.. The milky sea effect of constant light over a wide area comes from the luminous bacteria Vibrio harveyi, living alongside microalgal blooms. In order to create the effect of a milky sea, the populations of these bacteria are, as predicted, phenomenally large. Each contains an estimated 200 times more than the number of background, free-living bacteria spread over the continental shelf waters of all the oceans put together.. Scientists gained the first ever pictures of the milky sea effect in the fall of 2005. The photos, gleaned from images taken by the U.S. Defense Meteorological Satellite Program, show a glowing portion of the ocean that s about the size of ...

Vibrios are facultatively anaerobic bacteria that are metabolically similar to the Enterobacteriaceae. They are ubiquitous to oceans, coastal waters, and estuaries. The best known species is Vibrio cholerae, which can cause severe diarrheal illness in humans.The genus Vibrio consists of Gram-negative straight or curved rods, motile by means of a single polar flagellum. Vibrios are capable of both respiratory and fermentative metabolism.Classic cholera is characterised by an abrupt onset of vomiting and profuse watery diaorrhea. Fluid losses can be significant (up to 20 L/day) and hypovolemic shock and metabolic acidosis can cause death within a few hours of onset, especially in children. Mortality, in untreated cases, is as high as 60%. In the past 180 years, 7 pandemics were reported, usually of Bengali origin, with the latest pandemic originating in Indonesia in 1961 and moving to the Western hemisphere. In 1991, a cholera outbreak in Peru and 20 other countries in the Western hemisphere ...

The original aim of this thesis was to utilise Vibrio harveyi luciferase as a reporter of the expression of cell division genes during the cell cycle. Several plasmids expressing luxAB genes from ftsZ promoters were constructed. To achieve maximal luciferase expression, the ribosome binding site in front of the luxA gene was improved, which led to increased expression of luciferase. The level of expression of the improved luciferase reporter from plasmids was sufficiently high to be detected in single cells, although not high enough to be used in lower copy number constructs. However, luciferase activity showed significant fluctuations that did not appear to be linked to cell cycle events. These fluctuations made the detection of any cell cycle related changes in luciferase expression impossible. Another direction of this thesis is represented by the studies on the topology of the cell shape determining RodA protein. The ampicillin resistance levels were measured in 52 fusions with the topology ...

The Vibrio harveyi cgtA gene product belongs to a subfamily of small GTP-binding proteins, called Obg-like proteins. Members of this subfamily are present in diverse organisms ranging from bacteria to humans. On the other hand, the functions of these proteins in the regulation of cellular processes are largely unknown. Genes coding for these proteins are essential in almost all bacteria investigated thus far. However, a viable V. harveyi insertional mutant in the cgtA gene was described recently. Therefore, this mutant gives a unique opportunity to study functions of a member of the subfamily of Obg-like proteins. Here we demonstrate that the mutant cells often form long filaments with expanded, non-partitioned or rarely partitioned chromosomes. Such a phenotype suggests impairment of the mechanism of chromosome partition. Flow cytometric studies revealed that synchronization of chromosome replication initiation is also significantly disturbed in the cgtA mutant. Moreover, in contrast to ...

article{1079318, abstract = {Facultative anaerobic marine bacteria isolated from cultured clams Ruditapes decussatus and Ruditapes philippinarum were previously investigated using AFLP and 16S rRNA gene sequences analyses. The isolates formed two AFLP clusters and belonged to the genus Vibrio, more precisely to the Splendidus clade. In this study, phylogenetic analyses based on sequences of the housekeeping genes rpoA, rpoD, pyrH, atpA and recA supported their inclusion in that clade forming two well differentiated groups with respect to the rest of the species within the clade, and confirmed they formed two groups, separated from the rest of the species of the clade. DNA-DNA hybridizations demonstrated that the isolates constitute two novel Vibrio species, which can be phenotypically differentiated from their closest relatives.

Farming of Atlantic cod Gadus morhua, has become an important part of Norwegian aquaculture, but disease problems are frequent. Vibriosis caused by Vibrio splendidus has caused problems in aquaculture to early life stages of several marine species. It may also become a problem in cod hatcheries, as the bacterium is widely distributed in marine environments. The aim of the present study was to increase the understanding of V. splendidus infections in cod yolk sac larvae. Cod eggs were randomly selected from a single batch delivered by a commercial hatchery. Single eggs were transferred to wells in multi well dishes. Each well contained 2 ml of 80% aerated and sterile seawater. The eggs were challenged with 7 different strains of V. splendidus the same day as they arrived. The experiment did also include a negative control group consisting of unchallenged larvae and two positive control groups consisting of larvae challenged with two strains of Vibrio anguillarum. For each challenge strain 2 x 3 ...
Whiteleg shrimp (Litopenaeus vannamei)Â is one of the most important aquaculture commodity in Indonesia. However, the luminous disease primarily caused by Vibrio harveyi bacteria still becomes an obstacle in penaeid shrimp farming, especially in shrimp hatchery. This study was aimed to identify the presence of V. harveyi in L. vannamei through nested PCR using haemolysin gene primer. First, initial primers were designed using V. harveyi VIB 391 haemolysin gene sequence (accession number: DQ640264), flanking the position 133 to 756. This primer pairs were used to identify haemolysin gene in both V. harveyi MR5339 and V. harveyi 275 strain. Sequencing results from each sample showed 99% similarity with haemolysin gene sequence in Genebank. Furthermore, the sequence of V. harveyi MR5339 haemolysin gene was used to design the nested PCR primers. The first primer pairs of nested PCR have successfully amplified the haemolysin gene fragment of all V. harveyi strains samples from position 52 to 405. ...
The research was aimed to determine the present status of probiotics (Lactobacillus spp.) and pathogenic bacteria (Vibrio spp.) of culture pond as well as to determine whether the isolated probiotic Lactobacillus spp. can act as a controlling agent on experimentally pathogenic Vibrio spp. infected Penaeus monodon. In In-vitro test of gills and intestinal tracts, the potential antagonistic activity of Lactobacillus spp. toward Vibrio spp. was gradually observed at 4th hour of probiotic treatment. At 12th hour the viable count of Vibrio spp. was drastically reduced in gill from 2.33×105 to 1.03×103 (CFUg-1) and in intestinal tract 2.35×105 to 6.43×102 (CFUg-1). While, in In-vivo test, in case of muscle, gills and intestinal tract antagonistic activity of Lactobacillus spp. toward Vibrio spp. was noticed after 9 hours, 21 hours and 27 hours respectably of probiotic injected shrimps. However, only the result of in-vitro challenge test revealed that, Lactobacillus spp. significantly reduced the ...
lginate is a polysaccharide found within brown seaweeds and has been targeted as a carbon source for biofuel production. Alginate consists of α-L-guluronate (G) and β-D-mannuronate (M) linked in various patterns, which results in either a homo- or heteropolymeric structure. Alginate lyases are enzymes that degrade the linkage between G and M blocks and can have specificity to either polyG, polyM, or polyMG block degradation. The marine bacterium Vibrio splendidus 12B01 contains four putative alginate lyases which were investigated in this study. We identified, purified, and characterized the four PL7 alginates lyases. We found that these lyases have optimal activity between pH 7.5-8.5 and 20-25°C, consistent with use in a marine environment. Additionally, Ca 2+ is necessary for optimal enzyme activity. The binding constant (K m ) of the lyases toward alginate was found to be between 22 and 123 mM alginate and the maximum reaction rate (V max ) was found to be between 0.13 and 0.83 μM s -1 . ...

In aquaculture, vibriosis is known as a major bacterial disease in fish culture systems and can cause considerable loss in terms of production and processing (Toranzo et al. 2005). Many Vibrio species have been recognized as fish pathogens that can cause infection with various symptoms. For example, Vibrio scophthalmi infection results in hemorrhage on fish body surface and inner surface of the abdomen, severe enteritis, and ascites (Qiao et al. 2012); Vibrio ichthyoenteri infection cause opaque intestines and necrotizing fasciitis with high mortality rates (Ishimaru et al. 1996; Lee et al. 2012); Vibrio parahaemolyticus infection causes diseases not only in fish, shrimp, oysters, and mussels, etc. (Montilla et al. 1994; Quintoil et al. 2007), but also is important in public health and causes gastrointestinal disorders in humans who ingest contaminated fish and shellfish (Kubota et al. 2008; Iwamoto et al. 2010); and Vibrio vulnificus has been associated with vibriosis outbreaks in fish and ...

Cells of the marine bacterium, Ant-300, accumulate loosely bound amino acids during amino acid uptake. The fraction of amino acid taken up that exists in the loosely bound state depends on the substrate in question. Shock treatment studies indicate that, in general, the initial binding, uptake, and retention of amino acids are sensitive to reduced osmolarity and salt concentration. Cellular components that bind the amino acids arginine and lysine are released from the cells during shock treatment. Charge interactions appear to be responsible for the reversible formation of the ligand-protein complex. It is proposed that these components, presumably proteins, mediate the capture of the amino acids arginine and lysine at the surface of the cell. Chemotaxis provides the cell the opportunity to migrate from areas of low arginine concentration to areas of high arginine concentration. Arginine transport into the cell is mediated by two high affinity components with kinetic constants of 1.2 x 10⁻⁸ ...
Although turbot is produced in substantial quantities in aquaculture in Europe the major limitation in expansion of the industry is the supply of juvenile fish for on- growing. High mortalities can occur during early life stages during the critical times of transition from yolk sac larvae to feeding on rotifers and Artemia. There is good evidence that microorganisms are the major cause of the problems associated with early-feeding, as improved survival is seen when antibiotics are used or when larvae are reared in bacteria-free conditions. Several studies have shown that the bacterial flora of the larval turbot gut originates from the food. However, high levels of certain bacteria in the gut flora are not harmful, rather it is particular bacterial types that appear to determine larval rearing success. The present study concentrated on determining the virulence mechanisms of Vibrio splendidus DMC-1 (biovar 1), which was isolated from a batch of turbot larvae suffering very high mortality at a ...
Coral microbiomes are known to play important roles in organismal health, response to environmental stress, and resistance to disease. The coral microbiome contains diverse assemblages of resident bacteria, ranging from defensive and metabolic symbionts to opportunistic bacteria that may turn harmful in compromised hosts. However, little is known about how these bacterial interactions influence the mechanism and controls of overall structure, stability, and function of the microbiome. We sought to test how coral microbiome dynamics were affected by interactions between two bacteria: Vibrio coralliilyticus, a known temperature-dependent pathogen of some corals, and Halobacteriovorax, a unique bacterial predator of Vibrio and other gram-negative bacteria. We challenged reef-building coral with V. coralliilyticus in the presence or absence of Halobacteriovorax predators, and monitored microbial community dynamics with 16S rRNA gene profiling time-series. Vibrio coralliilyticus inoculation increased the

Vibrio nigripulchritudo is an emerging pathogen of farmed shrimp in New Caledonia and other regions in the Indo-Pacific. The molecular determinants of V. nigripulchritudo pathogenicity are unknown; however, molecular epidemiological studies have suggested that pathogenicity is linked to particular lineages. Here, we performed high-throughput sequencing-based comparative genome analysis of 16 V. nigripulchritudo strains to explore the genomic diversity and evolutionary history of pathogen-containing lineages and to identify pathogen-specific genetic elements. Our phylogenetic analysis revealed three pathogen-containing V. nigripulchritudo clades, including two clades previously identified from New Caledonia and one novel clade comprising putatively pathogenic isolates from septicemic shrimp in Madagascar. The similar genetic distance between the three clades indicates that they have diverged from an ancestral population roughly at the same time and recombination analysis indicates that these genomes have
Vibrio coralliilyticus is a global marine pathogen that has been found to cause disease in several marine organisms, including corals. This study is the first report of the isolation of V. coralliilyticus from a diseased Caribbean octocoral, Pseudopterogorgia americana. Five sister phylotypes were positively identified using 16S rRNA gene sequencing, recA probes specific for V. coralliilyticus, and rep-PCR fingerprinting. The antimicrobial resistance was compared between pathogenic strains of V. coralliilyticus and the Caribbean strains. First, the antimicrobial resistance of V. coralliilyticus-type strain ATCC BAA-450 was determined using an agar-overlay antimicrobial bioassay at 24°C and 27°C, temperatures which are relevant to its known temperature-dependent virulence.

Vibrio alginolyticus is a Gram-negative marine bacterium. It is medically important since it causes otitis and wound infection. It is also present in the bodies of animals such as pufferfish, where it is responsible for the production of the potent neurotoxin, tetrodotoxin. V. alginolyticus was first identified as a pathogen of humans in 1973. It occasionally causes eye, ear, and wound infections. It is a highly salt-tolerant species and can grow in salt concentrations of 10%. Most clinical isolates come from superinfected wounds that become contaminated at the beach. Tetracycline usually results in cure. V. alginolyticus is rare cause of bacteremia in immunocompromised hosts. Reilly, G D; Reilly, C A; Smith, E G; Baker-Austin, C (2011).

Coloured scanning electron micrograph (SEM) of Vibrio fischeri, Gram-negative, motile, bioluminescent, curved rod-shaped bacterium (prokaryote). Vibrio fischeri is a bioluminescent bacterium that occurs in global ocean environments. V. fischeri is most often found in a symbiotic relationship with certain deep sea marine life, such as the bobtail squid, within special light-organs.. V. fischeri causes the squid to produce a mucus substance that is secreted below the light organ on the squid. Cilia are used to draw more bacteria into this mucus matrix. The bacteria migrate into the light organ and colonize an area within it. They provide a light source for the squid to make it blend in with the ocean floor at night. Thus predators have a hard time seeing the squid. V. fischeri is a key research organism for examination of microbial bioluminescence, quorum sensing, and bacterial-animal symbiosis.

Vibrios are ubiquitous marine bacteria that have long served as models for heterotrophic processes and have received renewed attention because of the discovery of increasing numbers of facultatively pathogenic strains. Because the occurrence of specific vibrios has frequently been linked to the temperature, salinity, and nutrient status of water, we hypothesized that seasonal changes in coastal water bodies lead to distinct vibrio communities and sought to characterize their level of differentiation. A novel technique was used to quantify shifts in 16S rRNA gene abundance in samples from Barnegat Bay, N.J., collected over a 15-month period. Quantitative PCR (QPCR) with primers specific for the genus Vibrio was combined with separation and quantification of amplicons by constant denaturant capillary electrophoresis (CDCE). Vibrio populations identified by QPCR-CDCE varied between summer and winter samples, suggesting distinct warm-water and year-round populations. Identification of the CDCE ...
TY - JOUR. T1 - Functional domains of a zinc metalloprotease from Vibrio vulnificus. AU - Miyoshi, Shin-ichi. AU - Wakae, H.. AU - Tomochika, K. I.. AU - Shinoda, S.. PY - 1997. Y1 - 1997. N2 - Vibrio vulnificus, an opportunistic human pathogen causing wound infection and septicemia, secretes a 45-kDa metalloprotease (V. vulnificus protease; VVP). A plasmid which carries the entire vvp gene subcloned into pBluescriptIIKS+ was transformed into Escherichia coil DH5α for overproduction of the protease. The 45-kDa recombinant protease (rVVP) was isolated from the periplasmic fraction of the transformant by ammonium sulfate precipitation followed by column chromatography on phenyl Sepharose. Biochemical characterization of the isolated rVVP showed that the recombinant protease was identical to that produced by V. vulnificus. When rVVP was incubated at 37°C, a 35-kDa fragment was generated through autoproteolytic removal of the C-terminal peptide. This 35-kDa fragment (rVVP-N) was found to have ...
Vibrio abundance generally displays seasonal patterns. In temperate coastal areas, temperature and salinity influence Vibrio growth, whereas in tropical areas this pattern is not obvious. The present study assessed the dynamics of Vibrio in the Arabian Sea, 1-2 km off Mangalore on the south-west coast of India, during temporally separated periods. The two sampling periods were signified by oligotrophic conditions, and stable temperatures and salinity. Vibrio abundance was estimated by culture-independent techniques in relation to phytoplankton community composition and environmental variables. The results showed that the Vibrio density during December 2007 was 10- to 100-fold higher compared with the February-March 2008 period. High Vibrio abundance in December coincided with a diatom-dominated phytoplankton assemblage. A partial least squares (PLS) regression model indicated that diatom biomass was the primary predictor variable. Low nutrient levels suggested high water column turnover rate, ...
Microbial production is a promising method that can overcome major limitations in conventional methods of lycopene production, such as low yields and variations in product quality. Significant efforts have been made to improve lycopene production by engineering either the 2-C-methyl-D-erythritol 4-phosphate (MEP) pathway or mevalonate (MVA) pathway in microorganisms. To further improve lycopene production, it is critical to utilize metabolic enzymes with high specific activities. Two enzymes, 1-deoxy-D-xylulose-5-phosphate synthase (Dxs) and farnesyl diphosphate synthase (IspA), are required in lycopene production using MEP pathway. Here, we evaluated the activities of Dxs and IspA of Vibrio sp. dhg, a newly isolated and fast-growing microorganism. Considering that the MEP pathway is closely related to the cell membrane and electron transport chain, the activities of the two enzymes of Vibrio sp. dhg were expected to be higher than the enzymes of E. coli. We found that Dxs and IspA in Vibrio sp. dhg

Coloured scanning electron micrograph (SEM) of Vibrio vulnificus, Gram-negative, motile, curved rod-shaped bacteria (prokaryote). It is a human pathogen and causes an infection often after eating seafood, especially oysters. The bacterium occurs in marine environments such as estuaries, brackish ponds or coastal areas and it is highly salt tolerant. It is often present in contaminated waters and heated waters such as thermal or volcanic springs. Vibrio vulnificus can also enter the body through open wounds when swimming or wading, or via puncture wounds from the spines of fish such as tilapia. Symptoms include vomiting, diarrhoea, abdominal pain, decreased blood pressure and a blistering dermatitis. Severe symptoms and even death can occur if the bacterium enters the bloodstream (more common in people with compromised immune systems or liver disease).

The Boivin agent from Vibrio anguillarum was extracted with the use of 0.25M trichloroacetic acid (TCA). Chemical analysis revealed that the endotoxin contained approximately 35.1% protein, 18.1% carbohydrate, 39.3% lipid, 1.8% glucosamine and evidence of ethanolamine. Sixteen different amino acids made up the protein. The aliphatic amino acid concentration was 41.6%. The acidic amino acid content was higher than the basic amino acid content (25.8% vs. 14.4%) and glutamic and aspartic acid were the predominant amino acids. The carbohydrate fraction was composed of fucose (7.3%), arabinose (1.2%), deoxyglucose (tenative identification) (4.2%), galactose (0.8%), glucose (2.1%), and an unidentified sugar (2.5%). Injection of the endotoxin into mice resulted in an LD₅₀ value of 794 μg. When injected intramuscularly into juvenile chinook salmon, the endotoxin caused a zone of hemorrhaging at the site of injection. Upon prolonged storage of the endotoxin, this activity was lost. When incorporated ...

Inhibitory effect of commercial antibiotics and bioactive compounds produced by the isolate W3 against vibrios. Most of the antibiotics used could cause inhibition of all tested strains of V. harveyi (Table 1), Hence antibiotics could be used to control V. harveyi infections that affect aquaculture in Thailand. However, some of them such as chloramphenicol, furazolidone, tetracycline and oxonilic acid are now banned for use in aquaculture as previously mentioned. In general, β-lactam antibiotics such as ampicillin are preferred for use by shrimp farmers to treat luminous vibriosis disease since these groups of antibiotics do not cause significant side effects (Teo et al. 2002). Unfortunately, all tested strains in this study were resistant to ampicillin and this result is in agreement with Teo et al. (2002) who reported that many types of β-lactam antibiotics were no longer able to prevent vibriosis. In Thailand sulphamethoxazole is normally used in hatcheries against Vibrio sp.; however, in ...
Homologs of Toxin-Encoding Genes. Although V. fischeri is not known to be pathogenic, and strain ES114 is a beneficial symbiont, its genome carries homologs of Vibrio genes that may have toxin activity (Table 3, which is published as supporting information on the PNAS web site). As mentioned earlier, these include two CTX phage-encoded genes, zot (zona occludins toxin) and ace (accessory cholera enterotoxin), the latter of which has been found only in the V. cholerae and V. fischeri genome sequences. The proteins coded for by these genes have been shown to contribute to the structure of CTX phage (17), and their possible roles as toxins remain controversial (31, 32). At this time, it is not known whether the V. fischeri homologs of these two genes are expressed in this species, or whether they might play a role in this bacteriums symbiotic associations.. All sequenced Vibrio species carry genes encoding another putative toxin called RTX (repeats in structural toxins). RTX activity in V. ...
Thanks FOSL for getting her interview out……..We are presently looking at all the bacterial angles associated to these health issues being reported. One bacterium that everyone should take notice of is the Vibrio vulnificus (flesh eating strain of Vibrio). Vibrio vulnificus is a proteobacteria and a pathogen of humans. It causes wound infections, gastroenteritis, or primary septicemia (blood poisoning). Vibrio vulnificus causes disease in individuals who eat contaminated seafood (raw or undercooked oysters or have an open wound that is exposed to seawater. There have been several deaths due to this rare bacterial strain of Vibrio in the gulf region over the past couple of months. There are over 100 documented strains of this bacteria Vibrio with the possibility of thousands that have yet to be discovered. Back in June of this year the New York Times was reporting how scientist feared a possible bacterial plague erupting due to the Gulf spill. Are we now seeing a super bug? Is it an ...

Abstract The behavioral pattern of Vibrio parahaemolytics during the winter season (December 1988 to March 1989) in the water column, sediment, plankton and sinking particles was determined in a eutrophic marine environment. A total of 15 environmental parameters and seven microbial characteristics were examined. This halophile was isolated sporadically from bottom water and plankton materials, whereas it was undetectable in the surface water and sediment samples. However, V. parahaemolyticus was isolated from the sinking particles continuously throughout the sampling period with highest counts during February 1989. Out of 195 strains identified, 10 Vibrio spp. and 3 Listonella spp. were observed of which V. alginolyticus was predominantly isolated irrespective of the samples tested. Simple correlation and multiple regression analyses show that the occurrence of V. parahaemolyticus is not governed by any single biotic or abiotic factor of the environment. Possibly, the cumulative effect of all ...

The recent emergence of the human-pathogenic Vibrio vulnificus in Israel was investigated by using multilocus genotype data and modern molecular evolutionary analysis tools. We show that this pathogen is a hybrid organism that evolved by the hybridization of the genomes from 2 distinct and independent populations. These findings provide clear evidence of how hybridization between 2 existing and nonpathogenic forms has apparently led to the emergence of an epidemic infectious disease caused by this pathogenic variant. This novel observation shows yet another way in which epidemic organisms arise ...
