The protein mass spectrum of flagellin from each strain showed an envelope of multiply charged protein ions from which the reconstructed molecular mass profile was calculated. However, a peptide MS/MS analysis of a tryptic digest of a partially purified S-layer preparation from this strain did identify three flagellin-specific peptides in the sample (T39-50AADDAAGLAISE, T65-89NVQDGISVVQTAEGALEETGNILQR, and T92-107TLSVQSSNETNTAEER), indicating that this strain does produce flagellin protein, although in much smaller amounts. Clostridium: [ klo-strid´e-um ] a genus of gram-positive, obligate anaerobic or microaerophilic, spore-forming, rod-shaped bacteria. 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. Numerous ions were observed in the resulting MS/MS spectrum, including glycan-associated ions at m/z 524.1, 364.1, 204.1, and 161.1. PCR analysis of flagellar glycosylation islands.Chromosomal DNA was prepared from clinical isolates by using the DNeasy blood and tissue kit (Qiagen Inc., Mississauga, ON, Canada). For example, P. aeruginosa can utilize quaternary amin… The precise biological role of the glycosylation process in flagellar assembly has yet to be determined. Where possible, accurate mass measurements were performed for the glycan-related fragment ions in glycopeptide MS/MS spectra, and these were used to determine plausible elemental formulae of unknown glycans. (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). Of significance, neutral losses of 160 Da were observed from the precursor ion, suggesting that the ion observed at m/z 161.1 is glycan related. However, in the study by Stabler et al. The experiment was repeated three times over the period of seventy days, and no microenvironmental shifts were observed in the tumor area (11). Researchers have attempted to overcome this limitation by heat-inactivating C.sporogenes to produce its non-viable derivative before administration to a tumor culture. This kind of motility is a collective behavior accompanied by the production of long and hyperflagellate swarm cells. It should be noted that sequence diversity in the region of this gene which spans one of the primers used in the microarray may be responsible for the results obtained in the analysis of Janvilisri et al. Shape – Clostridium tetani is a slender, rod shape (bacillus) bacterium with a characteristic drumstick appearance due to the presence of spores.. 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). "Anticancer efficacy of systemically delivered anaerobic bacteria as gene therapy vectors targeting tumor hypoxia/necrosis.” Gene therapy 9.4 (2002): 291-296. Further inspection of the m/z 399.1 glycan oxonium ion MS/MS spectrum from a C. difficile 630 flagellin glycopeptide yielded information regarding the glycan composition. After being blotted dry, the grids were negatively stained with ammonium molybdate (1%, wt/vol). Therefore, C. sporogenes is classified as a harmless biosafety level I organism by the American Type Culture Collection (13). A similar pattern of glycan modification was observed for flagellins of other clinical C. difficile isolates. In contrast, analysis of the flagellin extract from the C. difficile 630::0240erm strain revealed a minor amount of a protein of a molecular mass corresponding to unmodified flagellin (Fig. [22] Weickert, M J, G H Chambliss, and H Sugiyama. In young culture discrete colonies are seen but thereafter actively motile cells spread on the surface of the plate in successive waves to form a thin filmy layer in concentric circles. Clostridium sporogenes are rod-shaped bacteria, typically linked in long chains, that are Gram-positive. Strains were grown on brain heart infusion (BHI) agar media supplemented with 0.5 g liter−1 cysteine-HCl, 5 mg liter−1 hemin, 1 mg liter−1 vitamin K1, and 1 mg liter−1 resazurin. Nucleotide sequence accession numbers.The C. difficile fliC DNA sequences have been deposited in GenBank under accession numbers GU048823 to GU048830. Submission, Review, & Publication Processes, Motility and Flagellar Glycosylation in Clostridium difficile, Copyright © 2009 American Society for Microbiology. Immediately downstream of fliC is a putative glycosyltransferase gene (CD0240). Clostridium botulinum strain A consists of a circular chromosome 3.9 Mega-base pairs in length with an overall GC content of 28.2%. This page was last edited on 12 February 2016, at 15:21. Malassezia furfur/Pityriasis Versicolor. Web. 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). From this initial analysis, it is apparent that the glycan present on flagellin from C. difficile BI-1 is quite distinct from that found on C. difficile 630. The elemental formula of the unknown fragment ion of m/z 116.1 suggested a methylated aspartic acid. In the clinical isolates, this locus showed considerable genetic diversity and increased size compared to that of C. difficile 630 (Fig. Infection with C. difficile can lead to severe diarrhea, abdominal pain, and further complications, such as pseudomembranous colitis, inflammation, and ulceration of the lining of the intestinal wall (5, 16). swarming motility. Méd. Further MS/MS spectra of the glycan-associated fragment ions were collected. Mechanically locked flagellar rotation is seen in Swarming growth is due to motility of bacteria. Motility. Initiation of Swarming Motility by Proteus mirabilis Occurs in Response to Specific Cues Present in Urine and Requires Excess ... tidine biosynthesis is specific for swarming (see Fig. Variability of both the motility phenotype and flagellin production among separate batch growths of some isolates is suggestive of a phase-variable phenotype. Of the motile gram-positive bacteria, flagellin from Listeria monocytogenes has been shown to be glycosylated with β-O-linked GlcNAc at up to six sites/flagellin (23). Top-down studies showed the flagellin proteins to have a mass greater than that predicted from the corresponding gene sequence. Top-down experiments were performed as described by Schirm et al. 1996-17-2 34-38) Palabras clave: Clostridium tetani, microbiología de suelos, tétanos, fenómeno de "swarming". Diversity of glycan modifications among C. difficile strains. BphP2 does not detectably regulate swarming motility. Asterisk, protein of a molecular mass corresponding to unmodified flagellin. For example, the peptide T202-212TMVSSLDAAK was observed as a doubly charged ion at m/z 730.8 in C. difficile 630. Bioinformatic analysis of C. difficile flagellar glycosylation locus.The genome of C. difficile 630 was recently published (25), and seven additional shotgun sequences of highly virulent C. difficile isolates from Quebec, Newfoundland, and Ontario, Canada, Minneapolis, MN, and Marne, France, are available through the DOE Joint Genome Institute integrated database (http://img.jgi.doe.gov Web. Thank you for sharing this Journal of Bacteriology article. One particular feature of this type of motility is the formation of dendritic fractal-like patterns formed by migrating swarms moving away from an initial location. Only the protein sample prepared from strain QCD32g58 failed to contain any major protein species corresponding to flagellin. [3] Bergey, D. H., William B. Whitman, Paul De Vos, George M. Garrity, and D. Jones. All C. difficile strains did display a spreading diffuse growth away from the inoculum stab in this assay, suggestive of a motile phenotype (Fig. ... Clostridium tetani - SM. [15] Liu, S. C., et al. "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. In this study, the genome-wide transcriptional response of B. cereus ATCC 14579 during swarming was analyzed. Elongated cells, gliding in the direction of their long axis can also slip past one another to maintain swarm cell flow. Motility is not as easily observed at 35–37 ºC as at room temperature (20–28 ºC). (12). C. sporogenes is considered a neutrophile, thus having an optimal pH range of about 6.0 – 7.6 (3). Accurate mass measurements where glycan-related ions were observed in peptide MS/MS spectra, were performed. (C) C. difficile 630::0240 erm. "Characteristics of Toxicity and Haemorrhagic Toxin Produced by Clostridium Sporogenes in Various Animals and Cultured Cells.” Journal of Medical Microbiology 46.4 (1997): 270-75. They are pleomorphic organi Unlike Clostridium botulinum, C. sporogenes does not carry plasmids that are responsible for neurotoxicity (22). 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 [15]). Features. MORPHOLOGY OF CLOSTRIDIUM TETANI. 6). They are from distinct outbreaks and display unique typing profiles. 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. 5B). 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. Clostridium perfringens usually produces a double zone of beta-hemolysis. In addition, we have identified through mutagenesis a glycosyltransferase gene from the flagellar biosynthesis locus; it is involved in the glycosylation process and, upon inactivation, leads to loss of surface-associated flagellin protein. This gene lies immediately downstream of the fliC gene in all strains. This observation suggested that the glycan biosynthesis assembly machinery in C. difficile is likely to be conserved, at least in part, among all strains. [8] Dang, Long H. et al. Enter multiple addresses on separate lines or separate them with commas. Swarming shares many similarities with biofilm communities, which are notable for their high resistance to antimicrobial agents. Accurate masses of the glycan oxonium and glycan-related fragment ions and most plausible empirical formulaa. "The architecture of the murein (peptidoglycan) in gram-negative bacteria: vertical scaffold or horizontal layer (s)?.” Journal of bacteriology 186.18 (2004): 5978-5987. 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. Molecular masses (in kDa) are shown to the left of the gel. UniProtKB. The complex oligosaccharides are composed of various components, which were identified by their characteristic neutral losses and corresponding glycan oxonium ions. 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. Tryptic peptides that had previously been observed to harbor the 398-Da glycan modification were observed to be unmodified on flagellin prepared from the C. difficile 630::0240erm strain. It is also been suggested that motility is an essential feature in the colonization hence pathogenicity of Helicobacter pylori . Strains of C. difficile were examined by stab inoculation onto standard motility agar plates (0.4% agar). Listeria spp: It is motile with a characteristic tumbling and rotating motility in broth cultures. Of significance, the observed major intact mass peaks were separated by a mass of ∼398 Da (see below). 26 terms. Erm-resistant colonies were examined by PCR using flanking primers for each gene (see Table S1 in the supplemental material) with the EBS universal primer (CGAAATTAGAAACTTGCGTTCAGTAAAC) to confirm integration into each gene of interest. (14), which indicated that the gene was divergent or absent in many isolates. However, a homolog of CD0240 (with >80% identity) which lies proximal to the fliC structural gene is present in all strains (GT1). "Isolation and characterization of bacteriophages active on Clostridium sporogenes.” Journal of bacteriology 87.2 (1964): 408-415. It has been reported that purified C. difficile flagellin monomers from various strains migrate at a molecular weight greater than that predicted from the translated DNA sequence, but flagellin monomers showed no reactivity with standard glycan staining kits (31). 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). Electrospray MS analyses of intact flagellin from strains of C. difficile. The alignment of all FliC protein sequences (see Fig. [12] Karbownik, Małgorzata, et al. However, due to high risk of infection and toxicity after the spore germinated in tumor-bearing animal (8), bacterial treatment is not widely accepted. Some strains are capable of producing bacteriocin-like substances that can inhibit other C. sporogenes strains (4). 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 Is a rapid (2–10 μm/s) and coordinated translocation of a bacterial population across solid or semi-solid surfaces, and is an example of bacterial multicellularit and swarm behaviour. The glycan is linked to the protein via the HexNAc moiety. While prevention through antibiotic stewardship and optimal management of disease is the most obvious strategy currently used, there is a great need for alternate methods of treatment. what is the shape of the calculus that is formed in the kidney secondary to proteus infection. Only strain CM-26 appeared to be nonmotile by this assay. Motility screening of fliC and CD0240 mutant strains.Each strain was grown overnight on supplemented BHI agar containing Erm. Lab 7: Endospore Stain and Bacterial Motility Last updated; Save as PDF Page ID 3446; Contributors and Attributions; A. ENDOSPORE STAIN . China is the leading peanut producer (∼37.5% of total production), followed by India, USA, Argentina and Vietnam (Fabra et al., 2010). We examined the abilities of cells from both broth- and agar-grown cultures in this manner, yet no obvious motility was observed. (B) nLC-MS/MS spectrum of the doubly protonated T135-144 glycopeptide ion 807.42+ from C. difficile BI-1. Primers spanning regions of the glycosylation island from QCD32g58 were used in reactions with chromosomal DNA and the Qiagen long-range PCR kit to determine the genetic content of each strain. (14), primers of approximately 70 bp specific for each of the flagellar glycosylation island genes from the QCD32g58 locus were included in the microarray, in addition to primers specific for CD0240 from C. difficile 630. The sites of glycosylation of flagellin monomers from a diverse number of bacterial species have all been shown to reside within the two surface-exposed domains (denoted D2 and D3) of the flagellin monomer when assembled within the flagellar filament (22). Determination of glycan attachment sites by ETD.Analysis of the sequence of glycopeptides did not reveal any N-linked sequons; therefore, the modification was thought to be O linked. [21] Vollmer, Waldemar, and Joachim-Volker Höltje. x; UniProtKB. 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. 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. If the stimuli is sensed as beneficial, the flagella orient cellular movement towards the stimuli (and visa versa). A number of spectra, however, were derived from peptides that appeared to possess a glycan modification. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. (B) C. difficile QCD32g58. "The stickland reaction.” Bacteriological reviews 18.1 (1954): 16. Flagellin protein purification.Flagellin proteins were isolated using the following procedure. MS analysis of modified tryptic peptides from flagellar proteins of C. difficile strains 630 and BI-1. (24) by using argon collision gas with collision energies ranging from 20 to 30 V. RF lens 1 voltage was increased from 30 to 125 V in order to obtain second-generation-fragment ion spectra. “Combination Bacteriolytic Therapy for the Treatment of Experimental Tumors.” Proceedings of the National Academy of Sciences of the United States of America 98.26 (2001): 15155–15160. Top-down analyses of C. difficile flagellins.Previously, we have shown that examination of intact flagellar proteins by electrospray ionization MS allows the identification of labile-glycoprotein-associated ions, in particular, glycan-related ions (24). In an attempt to increase the sequence coverage, flagellin tryptic peptides from strain BI-1 were separated by HPLC. “Metabolomics Analysis Reveals Large Effects of Gut Microflora on Mammalian Blood Metabolites.” Proceedings of the National Academy of Sciences of the United States of America 106.10 (2009): 3698–3703. Microbiology 1.3 (2003): 237. In this study, we show that flagellins of C. difficile strain 630 as well as those from recent clinical isolates of C. difficile are modified with diverse O-linked glycan moieties. Both swimming and swarming moti… Negative staining of bacterial cells and examination by electron microscopy revealed that, as expected, no flagellar filaments were produced in the fliC mutant strain (Fig. 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. staghorn calculi. Web. Flagellar glycosylation locus genes and similarity of predicted proteins to proteins in the microbial genome database. Analysis of the unusual carbohydrates obtained by nano-electrospray ionization-front-end collision-induced dissociation MS/MS. For sample preparation, grids were floated on a drop of bacterial cells for 5 min. An important distinction between C. sporogenes and its close relative C. botulinum is that C. sporogenes does not produce botulinum neurotoxins. The total mass of the glycopeptide was 3,160.24 Da (predicted peptide mass, 2,364.26 Da), which suggested modifications with two glycans of 398 Da. (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. Help. Each strain has three ORFs lying immediately downstream of the fliC gene which are transcribed in the same orientation and which encode glycosyltransferases (GT1, GT2, and GT3). 2, compare panels A and C). To play back at slow speed, choose 1/2x in QuickTime A/V Controls. The ability to glycosylate the flagellin protein appears to be required for optimal production at the cell surface. Glycopeptide-containing HPLC fractions were infused at 1 μl min−1 into the electrospray ionization source of an LTQ XL linear ion trap MS (Thermo Fisher Scientific, Ottawa, ON, Canada) capable of performing ETD. These were present in various combinations to form glycans of unique chain lengths (Table 1). is ‘b’ i.e., Clostridium tetani Swarming growth . Peptide type y and b fragment ions were observed at very low intensities, with the spectrum dominated by a glycan oxonium ion at m/z 399.1. PMC. “Functional Characterisation of Germinant Receptors in Clostridium Botulinum and Clostridium Sporogenes Presents Novel Insights into Spore Germination Systems.” Ed. In contrast, C. difficile strain 630 showed the lowest degree of flagellin sequence conservation, with 29 amino acid substitutions compared with the other sequences. Minor peaks were clearly visible at 36,208 and 37,166 Da (Fig. Plausible candidates, based upon residue mass for each residue, are HexNAc (203 Da), deoxyhexose (146 Da), and heptose (192 Da). coliswarm Smoke particles in darkfield and cells in phase contrast Swarm overtaking smoke particle Swarm overtaking a second smoke particle Tracking Each avi file is 1 s of video recorded at 30 frames/s. 7B). All strains examined in this study, with the exception of QCD32g58, M7465, and M9349, do not appear to be clonally related. PMC. (30). cystic fibrosis patients or severe burn patients). For example, C. sporogenes spores only release pathogens in tumor-specific vectors, having potential to be beneficial in cancer treatments aiming to reduce damage to non-cancerous cells within the host (20). This multicellular behavior has been mostly observed in controlled laboratory conditions and relies on two critical elements: 1 the nutrient composition and 2 viscosity of culture medium. The complete genome sequence of strain 630 as well as shotgun sequences of eight other strains are now available through the NCBI and DOE databases. 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. Weak fragment ions at m/z 204.1 and 161.1 were also observed. [20] Theys, J et al. The glycan appears to be O linked through the HexNAc residue. The same peptide was identified from the C. difficile 630::0240erm mutant as a doubly charged ion, at m/z 532.3, corresponding to the predicted mass of the unmodified peptide. 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. While the genetic content of this locus is conserved, it is quite distinct from that found in the C. difficile 630 genome. In a related fashion, when strain CM-26 was tested in motility agar, it appeared nonmotile, although when cells were grown for flagellin production, examination by SDS-PAGE demonstrated that flagellin protein could be extracted from the surface of bacterial cells. 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 . SDS-PAGE analysis of flagellin proteins.Flagellin purified from the cell surface of Clostridium difficile strains (listed in Table 1) was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) (Fig. Aliquots of each fraction were screened by nLC-MS/MS using the QTOF2 to confirm the peptide contents of each HPLC fraction. All C. difficile flagellins examined were shown to produce a glycan which is attached to serine and threonine residues in the protein sequence via a linking HexNAc monosaccharide. Swarming motility always involves cells that are long and flexible no matter how they are propelled. 3D). 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. 1983 ): 408-415 high-molecular-weight surface layer protein ( 6 ) strains 630 and BI-1 Clostridium....
