white shrimp (litopenaeus vannamei) recombinant lysozyme has antibacterial activity against gram negative bacteria: vibrio alginolyticus, vibrio parahemolyticus and vibrio cholerae.c-type lysozyme has been described as an antibacterial component of the shrimp innate defence system. we determined quantitatively the antibacterial activity of white shrimp (litopenaeus vannamei) recombinant lysozyme against three gram negative bacteria: vibrio alginolyticus, vibrio parahemolyticus and vibrio cholerae, using a turbidimetric assay with live bacteria and differential bacterial viable count after interaction with the protein. in conclusion, the antibacterial activity of recombinan ...200616098764
multiplex real-time pcr detection of vibrio cholerae.cholera is an important enteric disease, which is endemic to different regions of the world and has historically been the cause of severe pandemics. vibrio cholerae is a natural inhabitant of the aquatic environment and the toxigenic strains are causative agents of potentially life-threatening diarrhoea. a multiplex, real-time detection assay was developed targeting four genes characteristic of potentially toxigenic strains of v. cholerae, encoding: repeat in toxin (rtxa), extracellular secretor ...200616153727
incidence of class 1 integrons in multiple antibiotic-resistant gram-negative copiotrophic bacteria from the river torsa in india.the presence of class 1 integrons in multiple-antibiotic-resistant (mar) gram-negative copiotrophic bacteria from the river torsa in india was detected using a polymerase chain reaction (pcr)-based screening method. among 100 isolates that were resistant to at least five of the twelve antibiotics tested, 40 carried class 1 integrons, with inserted dna regions of 0.7-3.2 kb. carriage of integrons in strains of higher mar index was found to be statistically significant. dna sequencing was used to ...200616239097
conserved role of the linker alpha-helix of the bacterial disulfide isomerase dsbc in the avoidance of misoxidation by dsbb.in the bacterial periplasm the co-existence of a catalyst of disulfide bond formation (dsba) that is maintained in an oxidized state and of a reduced enzyme that catalyzes the rearrangement of mispaired cysteine residues (dsbc) is important for the folding of proteins containing multiple disulfide bonds. the kinetic partitioning of the dsba/dsbb and dsbc/dsbd pathways partly depends on the ability of dsbb to oxidize dsba at rates >1000 times greater than dsbc. we show that the resistance of dsbc ...200616280324
characterization of the ectoine biosynthesis genes of haloalkalotolerant obligate methanotroph "methylomicrobium alcaliphilum 20z".the genes involved in biosynthesis of the major compatible solute ectoine (1,4,5,6-tetrahydro-2-methylpyrimidine carboxylic acid) in halotolerant obligate methanotroph "methylomicrobium alcaliphilum 20z" were studied. the complete nucleotide sequences of the structural genes encoding l: -aspartokinase (ask), l-2,4-diaminobutyric acid transaminase (ectb), l-2,4-diaminobutyric acid acetyltransferase (ecta), and l-ectoine synthase (ectc) were defined and shown to be transcribed as a single operon e ...200616283251
sialylation regulates peripheral tolerance in cd4+ t cells.decreased binding by the 6c10 auto-antibody serves as a unique marker for cd4+ t cell unresponsiveness after the induction of t cell tolerance in vbeta8.1 tcr transgenic mice. we further define the nature of the epitope recognized by the 6c10 antibody to be a subset of thy-1 bearing incompletely sialylated n-linked glycans, and furthermore, we demonstrate that tolerant cd4+ t cells have an increased degree of cell-surface sialylation. to test the significance of the altered glycosylation state i ...200616291658
antimicrobial potentiality of the thioxanthene flupenthixol through extensive in vitro and in vivo experiments.the antipsychotic thioxanthene flupenthixol, possessing a trifluoromethyl substituent at position 2, exhibited a distinct antibacterial property against 352 strains of bacteria from 3 gram-positive and 13 gram-negative genera. the minimum inhibitory concentration (mic) of flupenthixol was determined by the national committee for clinical laboratory standards agar dilution method. mics ranged from 10-100 microg/ml in most of the strains, whilst some strains were inhibited at even lower concentrat ...200616316745
hyperinfectivity: a critical element in the ability of v. cholerae to cause epidemics?cholera is an ancient disease that continues to cause epidemic and pandemic disease despite ongoing efforts to limit its spread. mathematical models provide one means of assessing the utility of various proposed interventions. however, cholera models that have been developed to date have had limitations, suggesting that there are basic elements of cholera transmission that we still do not understand.200616318414
modelling, synthesis and biological evaluation of novel glucuronide-based probes of vibrio cholerae sialidase.the development of sialidase inhibitors is an area of continuing interest due to their potential use as therapeutic agents to combat viral and bacterial infections. herein, we report our studies involving the sialidase from the pathogen vibrio cholerae, through the modelling, synthesis and biological evaluation of mimetics of 5-acetamido-2,6-anhydro-3,5-dideoxy-d-glycero-d-galacto-non-2-enonic acid (neu5ac2en, 1), a naturally occurring sialidase inhibitor. these mimetics are o- and s-glycosides ...200616275104
chemotaxis between vibrio cholerae o1 and a blue-green alga, anabaena sp.the chemotactic response of vibrio cholerae o1 towards the mucilaginous sheath of anabaena sp. was investigated by capillary tube method using a virulent strain of v. cholerae o1, el tor, ogawa (3083-t) and its isogenic mutant (hap-1-t) that lacks the hap gene, which codes for mucinase (ha/protease). homogenates of anabaena sp. and purified mucin were used in this study as chemoattractants. results showed 5.7% bacterial accumulation of wild-type v. cholerae o1 towards 4% homogenates of anabaena ...200616207388
construction and evaluation of a o139 vibrio cholerae vaccine candidate based on a hema gene mutation.in this paper, we describe the development of vcusm2, a live metabolic auxotroph of vibrio cholerae o139. auxotrophy was achieved by mutating a house keeping gene, hema, that encodes for glutamyl-trna reductase, an important enzyme in the c5 pathway for delta-aminolevulenic acid (ala) biosynthesis, which renders this strain dependent on exogenous ala for survival. experiments using the infant mouse and adult rabbit models show that vcusm2 is a good colonizer of the small intestine and elicits gr ...200616102875
process development for a cuban cholera vaccine based on the attenuated strain vibrio cholerae 638.genetically modified vibrio cholerae strain 638 (biotype el tor, serotype ogawa) has previously been shown to be immunogenic in animal models and in human trials. our objective in the work reported herein was to describe the process development methods for the production of the 638 attenuated cholera vaccine. cell seed bank, culture of biomass, lyophilization and final formulation were processes were developed. the results show kinetics of culture that fulfils a logistical model. the microbiolog ...200616085342
determination of endotoxin by the measurement of the acetylated methyl glycoside derivative of kdo with gas-liquid chromatography-mass spectrometry.a gas-liquid chromatographic-mass spectrometric (glc-ms) method was applied to the detection of 3-deoxy-d-manno-2-octulosonic acid (kdo), a constituent of bacterial lipopolysaccharide (lps, endotoxin). samples containing lps were dried, methanolyzed with 2 m hcl in methanol at 60 degrees c for 1 h and acetylated with acetic anhydride and pyridine (1:1, v/v) solution at 100 degrees c for 30 min, then the products were analyzed by glc-ms or glc-msms. four acetylated methylglycoside methyl ester de ...200615932775
trophic regulation of vibrio cholerae in coastal marine waters.cholera disease, caused by the bacterium vibrio cholerae, afflicts hundreds of thousands worldwide each year. endemic to aquatic environments, v. cholerae's proliferation and dynamics in marine systems are not well understood. here, we show that under a variety of coastal seawater conditions v. cholerae remained primarily in a free-living state as opposed to attaching to particles. growth rates of free-living v. cholerae (micro: 0.6-2.9 day(-1)) were high (similar to reported values for the bact ...200616343318
resistance of the cholera vaccine candidate iem108 against ctxphi infection.the cholera toxin (ct) genes ctxab are carried on a lysogenic phage of vibrio cholerae, ctxphi, which can transfer ctxab between toxigenic and nontoxigenic strains of bacteria. this transfer may pose a problem when live oral cholera vaccine is given to people in epidemic areas, because the toxin genes can be reacquired by the vaccine strains. to address this problem, we have constructed a live vaccine candidate, iem108, which carries an el tor-derived rstr gene. this gene encodes a repressor and ...200616343705
immunosensor for the detection of vibrio cholerae o1 using surface plasmon resonance.an immunosensor for the detection of vibrio cholerae o1 was developed on the basis of surface plasmon resonance (spr). a protein g layer was fabricated by means of the chemical coupling between the free amine (-nh2) groups of protein g and the activated carboxyl groups present on a self-assembled monolayer (sam) consisting of a mixture of 11-mercaptoundecanoic acid (mua) and hexanethiol (molar ratio of 1:2). a monoclonal antibody, which was confirmed to be specific to v. cholera o1 by the wester ...200616326089
the regulatory roles of cell surface sialylation and n-glycans in human b cell lymphoma cell adhesion to galectin-1.surface sialylation and glycosylation of tumor cells is known to affect various biological phenomena. in the present study, we analyzed the regulatory roles of cell surface sialylation in cell adhesion to galectin-1 in the human diffuse large b cell lymphoma (dlbcl) cell line, hbl-2, and burkitt's lymphoma cell line, hbl-8. vibrio cholerae neuraminidase treatment enhanced hbl-2 cell adhesion to galectin-1, suggesting that sialic acid inhibits hbl-2 cell adhesion to galectin-1. the data from empl ...200616327992
a molecular model of the vibrio cholerae cytolysin transmembrane pore.the cytotoxic activity of some of the most pathogenic strains of vibrio cholerae is associated with a cytolysin protein (vcc), which forms oligomeric transmembrane pores and changes the permeability of intestinal cells. we present here a model structure of the transmembrane pore of vcc based on sequence comparison with other pore-forming toxins. vcc is suggested to form a transmembrane beta-barrel pore with a relatively large trans vestibule region. calculations of the electrostatic profile with ...200616330061
bile acids stimulate biofilm formation in vibrio cholerae.vibrio cholerae is a gram-negative bacterium that causes the acute diarrhoeal disease cholera. after the bacterium is ingested, it passes through the digestive tract, encountering various environmental stresses including the acidic milieu of the stomach and the toxic effects of bile in the duodenum. while these stresses serve as part of a host defence system, v. cholerae has evolved resistance mechanisms that allow it to evade these defences and establish infection. we examined the expression pr ...200616359328
territorial waters of the baltic sea as a source of infections caused by vibrio cholerae non-o1, non-o139: report of 3 hospitalized cases.a fatal infection with temporal relation to 2 other febrile infections caused by vibrio cholerae non-o1, non-o139 (ncv) occurred in finland in 2003. all infections were associated with contact with seawater. the patient who died had also eaten home-salted whitefish, tested positive for ncv, preceding his symptoms. all patients had compromising factors, and all strains were distinguishable by pulsed-field gel electrophoresis and negative for the ctx gene. these 3 cases illustrate that, despite be ...200616368474
identification of a constitutively active variant of luxo that affects production of ha/protease and biofilm development in a non-o1, non-o139 vibrio cholerae o110.pathogenesis of vibrio cholerae depends on the concerted action of numerous virulence factors that includes a secreted hemagglutinin (ha) protease. recent studies have evidenced that the expression of these virulence factors as well as the genes responsible for biofilm development is subject to control by quorum sensing in this organism. at low cell density, luxo, the pivotal regulator of quorum-sensing circuit, has been shown to be phosphorylated at aspartate-47. working in concert with sigma-5 ...200616376028
helicobacter pylori-associated chronic atrophic gastritis involving the gastric body and severe disease by vibrio cholerae.evidence has associated chronic infection by helicobacter pylori with chronic gastritis, low gastric acid production and an increased risk of life-threatening cholera. however, the relationship of specific patterns of histological damage in the gastric mucosa associated with h. pylori infection and the occurrence of cholera has not been described. the purpose of this study was to compare the gastric ph and histopathological findings in gastric biopsies taken from patients with severe diarrhoeal ...200616376396
recent progress in vaccines for amebiasis.the persistence of amebiasis as a global health problem, despite the availability of effective treatment, has led to the search for vaccines to prevent this deadly disease. recent clinical studies suggest that mucosal immunity could provide some protection against recurrent intestinal infection with e. histolytica, but there is contradictory evidence about protective immunity after amebic liver abscess. progress in vaccine development has been facilitated by new animal models that allow better t ...200616380333
autorepression of rctb, an initiator of vibrio cholerae chromosome ii replication.the rctb protein binds to the origin of replication of vibrio cholerae chromosome ii (chrii) and is required for oriciivc-based replication. here, we found that rctb acts as an autorepressor, inhibiting rctb transcription. integration host factor promotes rctb transcription, while dam and dnaa, factors required for replication of both v. cholerae chromosomes, influence rctb autorepression. thus, rctb appears to regulate chrii replication as both an initiator and a transcription repressor, and it ...200616385068
a vibrio cholerae relaxed (rela) mutant expresses major virulence factors, exhibits biofilm formation and motility, and colonizes the suckling mouse intestine.we have constructed a relaxed mutant of el tor biotype vibrio cholerae strain c7258 by disruption of the rela catalytic domain. the ability of the v. cholerae relaxed mutant to biosynthesize guanosine tetraphosphate and pentaphosphate was severely affected; the mutant showed a reduced growth rate in minimal medium that could be reversed by the addition of casamino acids, and it was thermosensitive. contrary to published findings, the new rela mutant still produced significant cholera toxin and t ...200616385069
fluoroquinolone-resistant vibrio cholerae isolated during a cholera outbreak in india.during the cholera epidemic of 2002 in and around hubli, south india, vibrio cholerae strains resistant to fluoroquinolones were isolated. among the isolates of v. cholerae non-o1, non-o139 serogroups, 55.9% and 47.1% were resistant to norfloxacin and ciprofloxacin, respectively. however, only 12.5% of the o1 serogroup strains were resistant to both norfloxacin and ciprofloxacin. though the o139 serogroup strains were susceptible to these antibiotics, they exhibited multidrug resistance. emergen ...200616246383
slyd proteins from different species exhibit high prolyl isomerase and chaperone activities.slyd is a putative folding helper protein from the escherichia coli cytosol, which consists of an n-terminal prolyl isomerase domain of the fkbp type and a presumably unstructured c-terminal tail. we produced truncated versions without this tail (slyd) for slyd from e. coli, as well as for the slyd orthologues from yersinia pestis, treponema pallidum, pasteurella multocida, and vibrio cholerae. they are monomeric in solution and unfold reversibly. all slyd variants catalyze the proline-limited r ...200616388577
antidiarrhoeal evaluation of aegle marmelos (correa) linn. root extract.a study was undertaken to evaluate the in vitro and in vivo antidiarrhoeal potential of chloroform extract of the root of aegle marmelos (correa) linn. the in vitro activity was determined by agar dilution and disc diffusion techniques. the extract was studied in vivo in rats. of the 35 tested pathogenic diarrhoea causing strains, the extract was found to be mostly active against the strains of vibrio cholerae, followed by escherichia coli and shigella spp. the in vitro activity was found to be ...200616397850

comparison of methods for recovering vibrio cholerae o1 from ice.alkaline peptone water (1% peptone, 1% nacl, ph 8.5) and trypticase soy yeast extract broth (tsyb) supplemented with 2.5% nacl (ph 8.5) or 1% nacl (ph 7.5) were evaluated as enrichment broths for the isolation of vibrio cholerae o1 from ice. thirty samples of sterile and nonsterile mineral water were inoculated with cell suspensions of this bacterium, quickly frozen, and stored for 3 days at--18 degrees c. after thawing, samples were analyzed by a three-tube most-probable-number technique. incub ...200616416923
dependent population dynamics between chironomids (nonbiting midges) and vibrio cholerae.vibrio cholerae, the causative agent of cholera, is a natural inhabitant of the aquatic ecosystem. chironomid (nonbiting midges) egg masses were recently found to harbour v. cholerae non-o1 and non-o139, providing a natural reservoir for the cholera bacterium. chironomid populations and the presence of v. cholerae in chironomid egg masses were monitored. all v. cholerae isolates were able to degrade chironomid egg masses. the following virulence associated genes were detected in the bacterial is ...200616420618
