Clostridium botulinum strain A consists of a circular chromosome 3.9 Mega-base pairs in length with an overall GC content of 28.2%. These are 2,804 and 2,405 Da larger than that predicted from the translated gene sequence of fliC and correspond to the attachments of six and seven glycan moieties of 398 Da. The cell wall consists of a thick layer of peptidoglycan, a polymer of amino acids and sugar (21). Swarming involves differentiation of vegetative cells into hyper-flagellated swarm cells that undergo rapid and coordinated population migration across solid surfaces. The recent emergence of the hypervirulent NAP1/027 strain in hospitals of North America has resulted in increased mortality rates (18, 19). In addition, PCRs with Erm-specific primers were used to confirm splicing of the retrotransposition-activated selectable marker. "Genome sequence of Clostridium sporogenes DSM 795T, an amino acid-degrading, nontoxic surrogate of neurotoxin-producing Clostridium botulinum.” Standards in genomic sciences 10.1 (2015): 1-12. ASM journals are the most prominent publications in the field, delivering up-to-date and authoritative coverage of both basic and clinical microbiology. Molecular masses (in kDa) are shown to the left of the gel. The mechanism by which MotI inhibits motility through MotA could work inone oftwo different ways. "Selenium Supplementation Improves Antioxidant Capacity in Vitro and in Vivo in Patients with Coronary Artery Disease The Selenium Therapy in Coronary Artery Disease Patients (SETCAP) Study.” National Center for Biotechnology Information 156 (2008). Flagellar structural genes fliC and flgB are colored black; for the flagellar glycosylation locus genes, glycosyltransferase genes are dark gray and precursor glycan biosynthesis genes are light gray. The C. difficile 630::fliCerm and C. difficile 630::0240erm strains no longer displayed a spreading phenotype in this motility agar, in contrast to the parent strain (Fig. In Campylobacter spp., for example, in addition to being required for flagellar assembly, flagellar glycosylation plays a role in autoagglutination properties of cells and subsequent virulence and contributes to antigenic specificity (11). Weak fragment ions at m/z 204.1 and 161.1 were also observed. Intense ions were observed at m/z 399.1, the putative glycan observed to modify FliC from this strain, and glycan-associated fragment ions were observed at m/z 284.1, 214.1, and 116.1 (indicated by an asterisk). This was further confirmed by the presence of a weak ion at m/z 204.1 in several glycopeptide MS/MS spectra and characteristic HexNAc-associated fragment ions (m/z 168.1 and 138.1 ). (30). Elongated cells, gliding in the direction of their long axis can also slip past one another to maintain swarm cell flow. AglZ is structurally similar to a protein important for S motility swarming, FrzS (see below), in that it contains an N-terminal pseudoreceiver domain and a long C-terminal coiled-coil domain (88, 89, 143). Domain Bacteria; Phylum Firmicutes; Class Clostridia; Order Clostridiales; Family Clostridaceae; Genus Clostridium Accurate mass determination of the glycan oxonium and glycan-related fragment ions was achieved using a number of neighboring peptide fragment ions as internal mass standards. Diversity of glycan modifications among C. difficile strains. Other Clostridia produce several different-looking colony types, so the culture appears mixed. It has been recently shown to have a regulatory function during A motility (see below) . Comparison of the observed protein intact mass of C. difficile 630 suggests that it corresponds to the flagellin protein FliC, bearing six or seven residues modified with a glycan of 398 Da. PMC. One hundred microliters of each tryptic digest was separated using a 4.6- by 250-mm Jupiter C18 reverse-phase column with a Phenomenex precolumn (SecurityGuard, Torrance, CA). Swarming motility in other Gram‐positive bacteria, such as Bacillus thuringiensis (Ghelardi et al., 2002) and Clostridium septicum (Macfarlane et al., 2001), is accompanied by dramatic changes in cell morphology, with the cells becoming filamentous and multinucleate as they enter the swarming state. Strains were grown on supplemented BHI plates under anaerobic conditions for 24 h. Bacteria were harvested in 500 μl distilled water and vortexed for 3 min before being centrifuged at 14,000 rpm in a benchtop centrifuge for 5 min. The ETD reaction time was adjusted for optimal fragmentation of each glycopeptide (35 ms).

Two sequential losses of m/z 199.12+ corresponds to the loss of a doubly charged glycan of a residue mass of 398.1 Da (indicated by the arrow). “Complete Genome Sequence of the Nonpathogenic Soil-Dwelling Bacterium Clostridium Sporogenes Strain NCIMB 10696.” Genome Announcements 3.4 (2015): e00942–15. "Development of indole-3-propionic acid (OXIGON™) for alzheimer’s disease.” Journal of Molecular Neuroscience 19.1-2 (2002): 213-217. Intense fragment ions were observed at m/z 284.1 and 214.1, with weaker ions at m/z 204.1 and 116.1. The reconstructed molecular mass profile of strain BI-1 showed a more complex spectrum, with major intact mass peaks at 35,106, 35,473, and 35,841 Da. The top-ranked elemental formula for m/z 204.1 glycan fragment ion was consistent with HexNAc, while the top-ranked elemental formula for m/z 161.1 fragment ion was consistent with a methylated deoxyhexose (Table 2). PLOS Pathogens 10.9 (2014): e1004382. The computer display is an overlay of the phase image where each cell is identified by a line running from its head to tail, colored either by cell identity (e.g., Edge by identity.avi) or by cell heading (Edge by heading.avi). Oxonium ions are visible at m/z 204.1 (HexNAc) and m/z 161.1. C. difficile 630 produces flagellin, which is glycosylated in O linkage at up to seven sites with a HexNAc residue, to which a methylated aspartic acid is linked via a phosphate bond. In addition, appropriate-sized PCR fragments were obtained when primers spanning the genes of the extended glycosylation island were used, demonstrating the conservation of this extended locus among the recent Canadian clinical isolates (data not shown).  ABIS Encyclopedia. This observation suggested that the glycan biosynthesis assembly machinery in C. difficile is likely to be conserved, at least in part, among all strains. Regnum Prokaryote, n.d. This process of flagellar glycosylation has also been shown to be required for motility in a number of other bacterial pathogens, including Campylobacter jejuni, Helicobacter pylori, and Aeromonas caviae, which are all known to colonize the gastrointestinal tract. Top-down studies showed the flagellin proteins to have a mass greater than that predicted from the corresponding gene sequence. Peptides were separated using a linear gradient of 5 to 60% acetonitrile and 0.5% formic acid over 40 min at a flow rate of 1 ml min−1. The ability to glycosylate the flagellin protein appears to be required for optimal production at the cell surface. ETD was then performed using fluoranthene as the anionic reagent and with supplementary activation enabled.

Ogura, Y. Noguchi, and S. Kumagai. While previous reports of C. difficile epidemics were restricted to single institutions or wards, more recently, there appears to be a wider distribution of outbreaks (20), accompanied by increasing severity of disease as well as a significant increase in the numbers of case fatalities reported (21). Although the majority of species can produce tendrils when … MS/MS spectra were acquired automatically on doubly, triply, and quadruply charged ions. Future work will be directed toward defining whether motility or the glycans play a role in colonization and in determining if there is a correlation between glycan structure and virulence of isolates. Flagellar glycosylation locus genes and similarity of predicted proteins to proteins in the microbial genome database. Inoculation of legume crop plants with effective rhizobial strains to increase productivity provides an ‘environmentally friendly’ alternative to chemical fertilization.  Lambin, Philippe, et al. With the recent development of mutagenesis tools for clostridial species, it will now be possible to determine if the glycosylation process is also required for flagellar assembly in C. botulinum . 5C). Clostridium septicum is a gram positive, spore forming, obligate anaerobic bacterium.. Clostridium septicum can cause gas gangrene, but unlike other Clostridium species like Clostridium perfringens, no trauma is necessary at the site of the infection.It is thought that the infection is established by hematogenous spread from the gastrointestinal tract. In contrast, flagellins from a number of C. difficile isolates from more recent outbreaks are modified in O linkage with a heterogeneous glycan containing up to five monosaccharide residues with masses of 204 (HexNAc), 146 (deoxyhexose), 160 (methylated deoxyhexose), and 192 (heptose). Due to its anaerobic nature and sporulation, C. sporogenes colonizes specific hypoxic areas of solid tumor when intravenously delivered into tumor-transplanted mice (16). Accurate masses of the glycan oxonium and glycan-related fragment ions and most plausible empirical formulaa. The diagram shows the region of the chromosome flanked by the fliC and flgB structural genes, which encode flagellin (FliC) and FlgB (rod protein), respectively. Of significance, the observed major intact mass peaks were separated by a mass of ∼398 Da (see below). Negative staining and examination of strain 630 and QCD32g58 cells by transmission electron microscopy revealed that filaments were present in QCD32g58, although in greatly reduced amounts relative to 630 (Fig. DISCUSSION. PCR analysis of flagellar glycosylation islands. No signal corresponding to the unmodified flagellin was observed. Resolution was typically 50,000 (50% valley definition). “Functional Characterisation of Germinant Receptors in Clostridium Botulinum and Clostridium Sporogenes Presents Novel Insights into Spore Germination Systems.” Ed. (B) The reconstructed molecular mass profile of FliC from C. difficile BI-1, showing intense peaks at 35,106, 35,473, and 35,841 Da and less intense peaks at 36,208 and 37,186 Da, all larger than the mass of FliC, which was predicted to be 30,901 Da. Motility was clearly visible in agar stabs for all strains with the exception of CM-26. Bioinformatic analysis of C. difficile genomes revealed diversity with respect to glycan biosynthesis gene content within the flagellar biosynthesis locus, likely reflected by the observed flagellar glycan diversity. (B) C. difficile QCD32g58.  Golovchenko, N. P., B. F. Belokopytov, and V. K. Akimenko. After 5 min, the bacterial cells were removed from the glycine buffer by centrifugation and supernatant retained. While the flagellin of Clostridium botulinum was shown to be glycosylated, the role of the glycosylation process in assembly and motility had not been investigated. Motility screening of fliC and CD0240 mutant strains.Each strain was grown overnight on supplemented BHI agar containing Erm. S6 in the sup- The striking feature of the swarming motility is that unlike the other modes, swarming is a quorum-sensing dependent collective movement of cells in many if not all swarming bacteria. C. difficile is known to express peritrichous flagella, and it has been observed that the level of adherence of flagellated strains to the mouse cecum is 10-fold higher than the level of adherence of nonflagellated strains (29). The available shotgun sequence data for strain QCD32g58 (orf2/GT2 and orf3/GT3) and for CIP107932 (orf1/GT1) likely contain sequencing errors, which result in truncation of the respective ORF. Therefore, C. sporogenes is classified as a harmless biosafety level I organism by the American Type Culture Collection (13). 2, compare panels A and C). As can be seen in Fig. Quizlet Live. "Glucose metabolism in Clostridium sporogenes and Clostridium sticklandii bacteria.” Mikrobiologiia 52.6 (1983): 869. It is important to acknowledge that two recent genomic microarray studies suggest that motility may not be required for virulence due to divergence in content of flagellar coding sequences among strains (14, 26). In the case of strain 630, the reconstructed molecular mass profile showed two major peaks at 33,559 and 33,160 Da (Fig. PCR analysis using primers specific to genes of this glycosylation island with chromosomal DNA from each clinical isolate characterized in this study confirmed the presence of a homolog of the GT1/CD0240 gene in each of these strains. S-layer protein extraction.Partially purified S-layer was obtained from C. difficile cells by resuspending growth from a single BHI plate (24 h) in 500 μl of 0.2 M glycine buffer, pH 2.2. The annotation of each GT into two ORFs is likely due to sequencing errors in these shotgun sequences. what is the shape of the calculus that is formed in the kidney secondary to proteus infection. In the C. difficile 630 locus, the genes annotated as a phosphatase gene (CD0241), sugar nucleotide transferase gene (CD0242), and hypothetical ORF (CD0243) are colored light grey. Collision-induced dissociation MS/MS analysis was performed on the glycopeptide ions to confirm their identity. BphP2 does not detectably regulate swarming motility. C. difficile 630 has the least complex complement of carbohydrate biosynthesis genes in this region. The MS/MS spectrum of this peptide showed a clear sequence of peptide type y and b ions, corresponding to the amino acid sequence T202-212TMVSSLDAALK. Initially, collision-activated dissociation MS/MS analysis was performed on the glycopeptide ions to confirm their identity. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. In Argentina, ∼90% of peanut production occurs in Córdob… In addition, the majority of the peptides in the tryptic digest were readily identified by nLC-MS/MS, giving 62% sequence coverage. It may be required for stability of subunit-subunit interactions within the flagellar filament or alternatively required for efficient secretion of the flagellin monomer through the basal body apparatus. 5A). (B) MS/MS spectrum of glycan fragment ion at m/z 284.1. 7, production of flagellin protein in the fliC mutant was completely abolished in contrast to that of the parent (lane 3). It is also been suggested that motility is an essential feature in the colonization hence pathogenicity of Helicobacter pylori . Selenocysteine has a lower reduction potential than cysteine, therefore, it is preferred over cysteine in proteins involved in antioxidant activity (19). However, due to high risk of infection and toxicity after the spore germinated in tumor-bearing animal (8), bacterial treatment is not widely accepted. These were present in various combinations to form glycans of unique chain lengths (Table 1). There are a variety of ways to determine the motility of a bacterium—biochemical tests as well as microscopic analysis. Although isolated from many infections, the role of C. sporogenes as pathogen has been not yet determined. Triple MS of m/z 284.1 showed a loss of phosphoric acid (98 Da), to give a fragment ion at m/z 186.1 (Fig. Protein knowledgebase. MS of isolated flagellins.Purified flagellin was exchanged into aqueous 0.2% formic acid (vol/vol) by using a Centricon YM-30 membrane filter (Millipore). The latter is shown in … Bacteria were grown under anaerobic conditions at 37°C in anaerobe chambers using Oxoid Anaerobe Paks. The reconstructed molecular mass profiles of C. difficile strains M9349 and M7465 also showed a more complex intact molecular mass profile, which closely resembled that of BI-1, with intact masses listed in Table 1. In addition to containing the three conserved GT ORFs, this extended locus also contains a number of ORFs encoding proteins with predicted enzymatic functions of relevance to glycan biosynthesis pathways. If the stimuli is sensed as beneficial, the flagella orient cellular movement towards the stimuli (and visa versa). We extracted this band from the gel, and peptide MS/MS analysis confirmed that this protein was the product of the fliC gene. (12). Sequencing reactions were run on a 3100 genetic analyzer from Applied Biosystems (Foster City, CA). "Colonisation ofClostridiumin the body is restricted to hypoxic and necrotic areas of tumours.” Anaerobe 4.4 (1998): 183-188. The positions at which flagella are inserted … The swarming motility of P. syringae B728a deletion mutants indicated that LOV-HK positively regulates swarming motility in response to blue light and BphP1 negatively regulates swarming motility in response to red and far-red light. A preliminary BLAST analysis of the flagellin genetic locus revealed that glycan biosynthesis genes were present in all genomes in close proximity to the flagellar structural gene fliC. ETD was performed using fluoranthene as the anionic reagent and with supplementary activation enabled. While the flagellin of Clostridium botulinum was shown to be glycosylated, the role of the glycosylation process in assembly and motility had not been investigated. In the clinical isolates, this locus showed considerable genetic diversity and increased size compared to that of C. difficile 630 (Fig. Determination of glycan linkage sites by ETD.Electron transfer dissociation (ETD) preserves delicate modifications during the fragmentation process and is ideal for identifying the linkage sites of O-glycans (8, 27).  Theys, J et al. Clostridium sporogenes is commonly isolated from soil, marine and fresh lake water sediment, preserved meat and dairy product, human intestines as well as human infections (3). The spectrum is dominated in the high-molecular-m/z region by the sequential loss of two carbohydrate moieties.  Betz, John V., and Kenneth E. Anderson. While nutrition is more commonly supplied by amino acid fermentation, glucose fermentation, where glucose is broken down into ethanol and carbon dioxide, can be utilized as a secondary source of nutrition. In this study, we show that inactivation of CD0240 gene by using the ClosTron mutagenesis system results in cells which are no longer motile and can produce only limited amounts of unglycosylated flagellin. Increasing the voltage of RF lens 1 promoted the formation of labile-protein-associated fragments ions in the orifice/skimmer region of the MS, allowing MS/MS spectra of the ions to be recorded. C. sporogenes exhibit motility using flagella (3). The high-m/z region is dominated by the sequential loss of m/z 160.1, 160.1, and 203.1 from what appears to be a trisaccharide. Accurate mass determination of the glycan oxonium ion and glycan-related fragment ions.Glycopeptide-containing HPLC fractions were infused at 1 μl min−1 into the electrospray ionization source of an LTQ XL Orbitrap MS (Thermo Fisher Scientific, Waltham, MA) and the MS/MS spectrum recorded over a period of 20 min. The flagellins of Clostridium botulinum have also been reported to be glycosylated with legionaminic or hexuronic acid derivatives (32), and preliminary evidence for glycosylation of C. tyrobutyricum flagellin has been reported (4). All C. difficile strains did display a spreading diffuse growth away from the inoculum stab in this assay, suggestive of a motile phenotype (Fig. Six different genes that encode selenocysteine-containing proteins are located within the genome. From these measurements, plausible elemental formulae were calculated for the 523-Da glycan and the m/z 204.1 and 161.1 glycan-related ions. (B) Motility stabs (0.175% agar) show C. difficile 630 (lane 1), C. difficile 630::0240erm (lane 2), and C. difficile 630::fliCerm (lane 3). Similar second-generation ion spectra were recorded for multiply charged protein ions from C. difficile strains M9349 and M7465, with product ion spectra similar to those observed for MS/MS of multiply charged protein ions from strain BI-1 (data not shown). (A) nLC-MS/MS spectrum of the doubly protonated T167-190 glycopeptide ion at 1,581.82+ from C. difficile 630. MS/MS analyses of the HPLC fractions showed glycopeptides with identical amino acid sequence but variable glycan modifications. No fragment ions corresponding to peptide type y or b ions were observed, suggesting that the observed fragment ions were more typical of those observed for glycan fragmentation. HPLC purification of tryptic peptides.Tryptic digests of flagellin were fractionated using an Agilent 1100 series high-pressure liquid chromatograph (HPLC) with a diode array detector (Agilent Technologies, Palo Alto, CA).

Recently, the genome sequences of three strains of Clostridium perfringens have been completed and we identified gene products involved in producing TFP in each strain. In this study, intact flagellin proteins were purified from strains of Clostridium difficile and analyzed using quadrupole time of flight and linear ion trap mass spectrometers. (D) C. difficile 630::fliC erm. These were stab inoculated and grown anaerobically at 37°C for 48 h (30). Single thiamphenicol-resistant colonies were resuspended in phosphate-buffered saline and plated at an appropriate dilution on BHI plates containing 2.5 μg ml−1 erythromycin (Erm) to select for the presence of a spliced erythromycin retrotransposition-activated selectable marker which indicates intron integration.

Proteus spp: P. mirabilis and P. vulgaris are actively motile (swarming motility). After being blotted dry, the grids were negatively stained with ammonium molybdate (1%, wt/vol). The low-m/z region of the spectrum is dominated by the carbohydrate oxonium ion (m/z 399.1) and what could be a fragmentation component (m/z 214.1). Structural characterization of unusual O-linked glycan moieties by MS/MS analyses.One of the challenges in structural elucidation of novel bacterial glycans is the relatively poor sensitivity of nuclear magnetic resonance, which requires milligram quantities of purified material. 7B).  Karbownik, Małgorzata, et al. x; UniProtKB. C. sporogenes are obligate anaerobes, so they can neither utilize nor survive in the presence of oxygen. 16S rDNA sequence analysis shows a 99.7% sequence similarity between Clostridium sporogenes and Clostridium botulinum strain A. Similarity between C. sporogenes and C. botulinum is furthered by the 2,016 orthologous genes shared between the two. Structural characterization of unusual O-linked glycan moieties by MS/MS analyses. Intact mass analysis of C. difficile flagellins.The observed masses of flagellin proteins from C. difficile strains 630, BI-1, M7465, and M9349 were obtained by infusion into a QTOF2 MS (Table 1). 3A), significantly greater than the predicted protein mass of 30,755 Da.
