Clostridium glycolicum ATCC ® 14880D™ Designation: Genomic DNA from Clostridium glycolicum TypeStrain=True Application:
Clostridium novyi (oedematiens) a Gram-positive, endospore- forming, obligate anaerobic bacteria of the class clostridia. It is ubiquitous, being found in the soil and faeces. It is pathogenic, causing a wide variety of diseases in man and animals. It comes in three types, labelled A, B, and a non-pathogenic type C distinguished by the range of toxins they produce. Some authors include Clostridium haemolyticum as Clostridium novyi type D. C novyi is closely related to Clostridium botulinum types C and D as Yoshimasa Sasaki et al. have demonstrated by 16S rDNA sequence analysis. Growth in culture proceeds through 3 stages: Initial growth wherein no toxin is produced; vigorous growth wherein toxin is produced; and spore formation wherein endospores are formed and toxin production decreases. It is suggested that type C may be type B that forms spores more readily so does not go through the toxin-production stage. Isolating and identifying C novyi is difficult due to its extreme anaerobic nature. ...
Clostridium innocuum (CLOIN) is an anaerobic, non-motile, gram-positive bacterium that reproduces by sporulation. While there are over 130 species of Clostridia, C. innocuum is the third most commonly isolated. Although it is not normally considered an aggressive human pathogen, it has been isolated in some disease processes. C. innocuum and other Clostrida line the oropharynx and gastrointestinal tract, and are considered normal gut flora. Anaerobic gram-positive bacilli affecting human beings are generally divided into two distinct groups, those that form spores (Clostridium spp) and those that do not form spores. Within the spore-forming group of Clostridium species, some are very pathogenic or toxigenic (C. perfringens) while others are rarely pathogenic. Identification and differentiation between anaerobic gram-positive bacteria in a clinical laboratory can be a very difficult task. C. innocuum forms white, glossy, raised colonies and exhibits a chartreuse fluorescence. It is a small, ...

Abstract: A group-specific PCR-based denaturing gradient gel electrophoresis (DGGE) method was developed and combined with group-specific clone library analysis to investigate the diversity of the Clostridium leptum subgroup in human feces. PCR products (length, 239 bp) were amplified using C. leptum cluster-specific primers and were well separated by DGGE. The DGGE patterns of fecal amplicons from 11 human individuals revealed host-specific profiles; the patterns for fecal samples collected from a child for 3 years demonstrated the structural succession of the population in the first 2 years and its stability in the third year. A clone library was constructed with 100 clones consisting of 1,143-bp inserts of 16S rRNA gene fragments that were amplified from one adult fecal DNA with one forward universal bacterial primer and one reverse group-specific primer. Eighty-six of the clones produced the 239-bp C. leptum cluster-specific amplicons, and the remaining 14 clones did not produce these ...

The transport of 99MoO42- into dinitrogen-fixing cells of Clostridium pasteurianum was investigated. Transport of molybdate in this organism is energy dependent; sucrose is required in the minimal media, and the system is inhibited by the glycolysis inhibitors, NaF, iodoacetic acid, and arsenate. The cells accumulate molybdate against a concentration gradient, and the uptake shows a marked dependence on temperature (optimum 37 C) and pH (optimum 6.0). The rate of molybdate uptake with increasing molybdate concentrations shows saturation kinetics with an apparent Km and Vmax of 4.8 X 10(-5) M and 55 nmol/g of dry cells per min, respectively. Inhibition studies with the anions SO42-, S2O32-, WO42-, and VO32- show that SO42- and WO42- competitively inhibit MoO42- uptake (apparent Ki [SO42-] is 3.0 X 10(-5) M; apparent Ki [WO42-] is 2.4 X 10(-5), whereas S2O32- and VO32- have no inhibitory effect. Exchange experiments with MoO42- show that only a small percentage of the 99MoO42- taken up by the ...
Conference Comment: The contributor provides a good summary of C. piliforme, an atypical member of the genus Clostridium. Other members of the clostridia are large, Gram positive spore forming bacteria with straight or slightly curved morphology, in contrast the filamentous, Gram negative spore forming C. piliforme.(2) Further differentiating C. piliforme from other clostridia is the fact that it does not possess characteristics that allow its inclusion into one of the three general categories of the other pathogenic members of the genus. These categories of clostridia are neurotoxic (C. tetani, C. botulinum types A-G), histotoxic (C. chauvoei, C. septicum, C. novyi types A and B, C. perfringens type A, C. sordellii, C. hemolyticum), and enteropathogenic/enterotoxemia-producing (C. perfringens types A-E, C. difficile, C. colinum, C. spiroforme).(2 ...
Some pathogenic spore-forming bacilli employ a binary protein mechanism for intoxicating the intestinal tracts of insects, animals, and humans. These Gram-positive bacteria and their toxins include Clostridium botulinum (C2 toxin), Clostridium difficile (C. difficile toxin or CDT), Clostridium perfringens (ι-toxin and binary enterotoxin, or BEC), Clostridium spiroforme (C. spiroforme toxin or CST), as well as Bacillus cereus (vegetative insecticidal protein or VIP). These gut-acting proteins form an AB complex composed of ADP-ribosyl transferase (A) and cell-binding (B) components that intoxicate cells via receptor-mediated endocytosis and endosomal trafficking. Once inside the cytosol, the A components inhibit normal cell functions by mono-ADP-ribosylation of globular actin, which induces cytoskeletal disarray and death. Important aspects of each bacterium and binary enterotoxin will be highlighted in this review, with particular focus upon the disease process involving the biochemistry and modes of

Clostridium pasteurianum is emerging as a prospective host for the production of biofuels and chemicals, and has recently been shown to directly consume electric current. Despite this growing biotechnological appeal, the organisms genetics and central metabolism remain poorly understood. Here we present a concurrent genome sequence for the C. pasteurianum type strain and provide extensive genomic analysis of the organisms defence mechanisms and central fermentative metabolism. Next generation genome sequencing produced reads corresponding to spontaneous excision of a novel phage, designated φ6013, which could be induced using mitomycin C and detected using PCR and transmission electron microscopy. Methylome analysis of sequencing reads provided a near-complete glimpse into the organisms restriction-modification systems. We also unveiled the chief C. pasteurianum Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) locus, which was found to exemplify a Type I-B system. Finally, we show

SunEthanol, a company that is developing microbes to produce cellulosic ethanol, announced on Nov. 18 that has raised $25 million in Series B financing and that it is changing its name to Qteros Inc. The funding will allow the company to scale up its process from the pilot plant to commercial operations, and hire additional engineers and scientists, company officials said. Plans call for a demonstration plant by 2010 and commercial production in 2011. The two year old Hadley, MA company is developing the Q Microbe™ (Clostridium phytofermentans), a lollipop-shaped microscopic organism that the company claims has unique properties that make it ideally suited to the production of cellulosic ethanol from a variety of non-food plant materials. Dr. Susan Leschine, Qteros Chief Scientist and co-founder, is the University of Massachusetts, Amherst microbiology professor who, nearly 10 years ago, first collected a sample of the Q Microbe™ near the Quabbin Reservoir in Massachusetts.

Sampling frequency. Both rivers were sampled once a month for 42 months (September 2007 to March 2011). The sampling was done on Mondays between 08:00 and 08:30, according to the SANS 5667-6 (SANS, 2006) guideline. The samples were transported on ice and analysed in duplicate.. Microbiological analysis. The aerobic colony count (ACC) was used to give an indication of the size of the microbial population in the water. The aerobic and anaerobic spore formers were used to establish the presence of Bacillus and Clostridium strains. Total coliforms, faecal coliforms, E. coli and intestinal enterococci were used as indicator organisms for faecal contamination (Busta et al., 2003). The index organisms (Staphylococcus, Salmonella and Listeria) were used as indicators of the possible presence of related pathogens, i.e., Clostridium, Campylobacter, Giardia, Cryptosporidium, and other Gram-negative species (Busta et al., 2003)..

General Information: Solvent-producing bacterium. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive clostridia-like ancestors with a low GC content in DNA. Some species are capable of producing organic solvents (acetone, ethanol, etc,), molecular hydrogen and other useful compounds. There are also species that can fix molecular nitrogen and thus are important participants in ...

Reduction of fully oxidized Clostridium pasteurianum 8-Feox.,ox. ferredoxin by using pulse-radiolysis techniques yields the half-reduced species 8-Feox.,red. ferredoxin. The subsequent oxidation of 8-Feox.,red. ferredoxin with Co(NH3)5Cl2+ was studied. From a comparison with stopped-flow studies on the 2:1 Co(NH3)5Cl2+ oxidation of 8-Fered.,red. ferredoxin to the 8-Feox.,ox. form it is concluded that there is no redox co-operativity between the two 4-Fe centres in these reactions. ...

The increase in glycerol obtained as a byproduct of biodiesel has encouraged the production of new industrial products, such as 1,3-propanediol (PDO), using biotechnological transformation via bacteria like Clostridium butyricum. However, despite the increasing role of Clostridium butyricum as a bio-production platform, its metabolism remains poorly modeled. We reconstructed iCbu641, the first genome-scale metabolic (GSM) model of a PDO producer Clostridium strain, which included 641 genes, 365 enzymes, 891 reactions, and 701 metabolites. We found an enzyme expression prediction of nearly 84% after comparison of proteomic data with flux distribution estimation using flux balance analysis (FBA). The remaining 16% corresponded to enzymes directionally coupled to growth, according to flux coupling findings (FCF). The fermentation data validation also revealed different phenotype states that depended on culture media conditions; for example, Clostridium maximizes its biomass yield per enzyme usage under
The nucleotide sequence of the celY gene coding for the thermostable exo-1,4-β-glucanase Avicelase II of Clostridium stercorarium was determined. The gene consists of an ORF of 2742 bp which encodes a preprotein of 914 amino acids with a molecular mass of 103 kDa. The signal-peptide cleavage site was identified by comparison with the N-terminal amino acid sequence of Avicelase II purified from C. stercorarium. The celY gene is located in close vicinity to the celZ gene coding for the endo-1,4-β-glucanase Avicelase I. The CelY-encoding sequence was isolated from genomic DNA of C. stercorarium with the PCR technique. The recombinant enzyme produced in Escherichia coli as a LacZ'-CelY fusion protein could be purified using a simple two-step procedure. The properties of CelY proved to be consistent with those of Avicelase II purified from C. stercorarium. Sequence comparison revealed that CelY consists of an N-terminal catalytic domain flanked by a domain of 95 amino acids with unknown function
Increasing demand for the production of renewable fuels has recently generated a particular interest in microbial production of butanol. Anaerobic bacteria, such as Clostridium spp., can naturally convert carbohydrates into a variety of primary products, including alcohols like butanol. The genetics of microorganisms like Clostridium acetobutylicum have been well studied and their solvent-producing metabolic pathways characterized. In contrast, less is known about the genetics of Clostridium spp. capable of converting syngas or its individual components into solvents. In this study, the type of strain of a new solventogenic Clostridium species, C. carboxidivorans, was genetically characterized by genome sequencing. C. carboxidivorans strain P7T possessed a complete Wood-Ljungdahl pathway gene cluster, involving CO and CO2 fixation and conversion to acetyl-CoA. Moreover, with the exception of an acetone production pathway, all the genetic determinants of canonical ABE metabolic pathways for acetate,
Lethal Toxin from Clostridium sordellii (TcsL), which is casually involved in the toxic shock syndrome and in gas gangrene, enters its target cells by receptor-mediated endocytosis. Inside the cell, TcsL mono-O-glucosylates and thereby inactivates Rac/Cdc42 and Ras subtype GTPases, resulting in actin reorganization and an activation of p38 MAP kinase. While a role of p38 MAP kinase in TcsL-induced cell death is well established, data on a role of p38 MAP kinase in TcsL-induced actin reorganization are not available. In this study, TcsL-induced Rac/Cdc42 glucosylation and actin reorganization are differentially analyzed in p38alpha−/− MSCV empty vector MEFs and the corresponding cell line with reconstituted p38alpha expression (p38alpha−/− MSCV p38alpha MEFs). Genetic deletion of p38alpha results in reduced susceptibility of cells to TcsL-induced Rac/Cdc42 glucosylation and actin reorganization. Furthermore, SB203580, a pyridinyl imidazole inhibitor of p38alpha/beta MAP kinase, also protects
CRISPR/Cas-based genetic engineering has revolutionised molecular biology in both eukaryotes and prokaryotes. Several tools dedicated to the genomic transformation of the Clostridium genus of Gram-positive bacteria have been described in the literature; however, the integration of large DNA fragments still remains relatively limited. In this study, a CRISPR/Cas9 genome editing tool using a two-plasmid strategy was developed for the solventogenic strain Clostridium acetobutylicum ATCC 824. Codon-optimised cas9 from Streptococcus pyogenes was placed under the control of an anhydrotetracycline-inducible promoter on one plasmid, while the gRNA expression cassettes and editing templates were located on a second plasmid. Through the sequential introduction of these vectors into the cell, we achieved highly accurate genome modifications, including nucleotide substitution, gene deletion and cassette insertion up to 3.6 kb. To demonstrate its potential, this genome editing tool was used to generate a marker-free

Iron reduction in Gram-positive bacteria is not well understood yet, even if it has been investigated in some extent for Gram-positive bacteria. The mechanisms involved in the delivery of electrons to a solid terminal electron acceptor like iron oxides have not been defined. Clostridium acetobutylicum is an appropriate Gram-positive bacterium to study those mechanisms as genetic tools have been developed due to its industrial interest, allowing easy targeted and random mutagenesis. In this Masters project, phenotype of two mutants, whose dihydroorotate dehydrogenase 1B (pyrD) or ferredoxin hydrogenase (hydA) gene have been knocked out through ClosTron mutagenesis, have been characterized and no phenotype diverging from the wild strain has been detected. However, evidences of flavin presence in the spent growth medium have been observed during experiment. An attempt to measure their redox state, either by direct measurement or through the addition of AQDS, has been done but results are ...

Preliminary work has been done on the formulation of a new solventogenic clostridial fermentation medium based on the use of corn steep liquor (CSL). CSL is a by-product of the corn wet-milling industry, and has been used primarily as a feed supplement in the livestock industry. This nutrient-rich medium is an ideal base for use in a bacterial fermentation medium. A medium developed from CSL has been found to support good bacterial growth while allowing a level of solvent production approaching that of complex, more expensive clostridial growth media. When used in combination with C. beijerinckii, BA101, this newly developed medium holds promise to increase the cost-effectiveness of the ABE fermentation. (Abstract shortened by UMI ...
Pure bacterial strains give better yields when producing H2 than mixed, natural communities. However the main drawback with the pure cultures is the need to perform the fermentations under sterile conditions. Therefore, H2 production using artificial co-cultures, composed of well characterized strains, is one of the directions currently undertaken in the field of biohydrogen research. Four pure Clostridium cultures, including C. butyricum CWBI1009, C. pasteurianum DSM525, C. beijerinckii DSM1820 and C. felsineum DSM749, and three different co-cultures composed of (1) C. pasteurianum and C. felsineum, (2) C. butyricum and C. felsineum, (3) C. butyricum and C. pasteurianum, were grown in 20 L batch bioreactors. In the first part of the study a strategy composed of three-culture sequences was developed to determine the optimal pH for H2 production (sequence 1); and the H2-producing potential of each pure strain and co-culture, during glucose (sequence 2) and starch (sequence 3) fermentations at the optimal

Good call!. I believe you are most likely correct in your assumption. People his age are prone to an infection of the digestive track called "C-Diff"(Clostridium difficile) which is often contracted from a previous stay in the hospital, although a small portion of the population has this bacterium naturally present in their colon..

In the last few years the spoilage of vacuum-packed, refrigerated beef due to psychrophilic and psychrotolerant clostridia, including production of gas inside the pack, has gained in importance. In addition to C. estertheticum and C. gasigenes, further psychrophilic clostridia have been described, which are able to cause Blown Pack Spoilage. Because there are divergent descriptions of these spoilage-causing bacteria, the phenotypic characteristics of the reference strains of six psychrotolerant clostridia were examined and the results were compared. In doing so, dissent results have been detected especially concerning hemolysis on blood agar plates as well as size of the vegeta- tive cells. The examination of C. gasigenes showed that there are distinct transverse pro- cesses in the last third of the rods of C. gasigenes, which, at present state of knowledge, have not been mentioned in the literature yet. The intention of this study was, to get more findings about the occurrence and the ...

Over 200 years ago, a surgeon in New York City, named Dr. William Coley, discovered that he could fight the tumors of cancer patients by injecting them with live Streptococcus bacteria. After some trial and error, he switched to using dead bacteria, and ultimately treated over 1000 patients with what were eventually dubbed "Coley toxins." The advent of current cancer treatments such as radiation, chemotherapy and surgery pushed Coleys methods into the background. Interestingly, though, it was discovered in 1999 that his success rates were similar to those for modern cancer therapies.. For over a decade, Bert Vogelstein, a cancer geneticist at Johns Hopkins University in Baltimore, Maryland, has been using the soil-dweller bacterium, Clostridium novyi. This bacterium thrives in areas of low oxygen, which is typical of tumors. While initial results were promising in rats, the researchers then extended the study to 16 pet dogs, and found that the tumors shrank or disappeared in six of the dogs, ...

Clostridium perfringens is found in soil and in the intestines of humans and animals. In contaminated food, it produces a toxin that causes a form of food poisoning.
Infections with bacterium Clostridium difficile have rapidly become a significant medical problem in hospitals and long-term care facilities. The bacteria cause diarrhea and life-threatening inflammation of the colon by producing toxins that kill the endothelial cells that form the lining of the gut. Although a natural inhibitor of these toxins, called InsP6, works in the…

Clostridium butyricum phosphatidyltransferase: from Clostridium butyricum; catalyzes transfer of the phosphatidyl moiety of phosphatidylethanolamine, phosphatidylglycerol or phosphatidylserine to primary alcohols such as glycerol, serine and ethanolamine; catalyze transfer of both the diacyl and alkenyl acyl forms of glycerophospholipids, but the diacyl forms are used preferentially
Cultures of Clostridium formicoaceticum and C. thermoaceticum growing on fructose and glucose, respectively, were shown to rapidly oxidize CO to CO2. Rates up to 0.4 μmol min−1 mg of wet cells−1 were observed. Carbon monoxide oxidation by cell suspensions was found (i) to be dependent on pyruvate, (ii) to be inhibited by alkyl halides and arsenate, and (iii) to stimulate CO2 reduction to acetate. Cell extracts catalyzed the oxidation of carbon monoxide with methyl viologen at specific rates up to 10 μmol min−1 mg of protein−1 (35°C, pH 7.2). Nicotinamide adenine dinucleotide, nicotinamide adenine dinucleotide phosphate and ferredoxin from C. pasteurianum were ineffective as electron acceptors. The catalytic mechanism of carbon monoxide oxidation was "ping-pong," indicating that the enzyme catalyzing carbon monoxide oxidation can be present in an oxidized and a reduced form. The oxidized form was shown to react reversibly with cyanide, and the reduced form was shown to react reversibly ...
Gas gangrene or C. myonecrosis is a rare life-threatening illness that results in necrotising soft tissue injury. Early recognition and diagnosis is imperative as the disease course is rapid. Risk factors for developing fulminant soft tissue infections include trauma, immunosupression, diabetes and vascular disease. More specifically, gas gangrene is commonly associated with patients post surgery or trauma due to the presence of Clostridium perfringes. Only 16% of cases occur spontaneously and the organisms responsible is usually the more virulent C. septicum.1 2 Clostridium is an anaerobic, spore-forming, positive rod.2 It constitutes part of the normal flora of the gastrointestinal tract. There are over 100 different strains of Clostridium of varying clinical significance. C. septicum infection resulting in bacteraemia is extremely rare. Larson et al 3 reviewed all cases of Clostridium infection at their institution from 1966 to 1993. Among 241 cases of Clostridium, 32 cases were C. septicum ...

Thiolase of Clostridium acetobutylicum is an important enzyme involved in both, acid and solvent fermentation. Two thiolase genes (thlA and thlB) have been cloned and sequenced from Clostridium acetobutylicum DSM 792, showing high homology to each other and to thiolases of PHA-synthesizing bacteria. The thlA gene is identical to the gene already cloned and sequenced from strain ATCC 824 (Stim- Herndon et al., 1995, Gene 154: 81-85). Using primer extension and S1 nuclease analysis a transcriptional start site was identified 102 bp upstream of the thlA start codon. This site was preceded by a region that exhibits high similarity to the s70 consensus promoter sequences of Gram-positive and -negative bacteria. Regulation of thlA and thlB was studied at the transcriptional level to elucidate the specific function of each gene. Non-radioactive primer extension analysis using fluorescein-labelled oligonucleotides and Northern blot analysis revealed high levels of thlA transcripts in acid- and ...
Production and application of bio-based industrial products are increasingly important to the nations economic development. The goal of this work was to develop a novel bioprocess to economically produce butyric acid from low-value agricultural commodities. Butyric acid has many important applications in chemical, food, and pharmaceutical industries. Conventional fermentation technologies for butyric acid production are limited by low reactor productivity, product concentration, and yield. In this study, novel metabolic engineering approaches, at both molecular biology and process engineering levels, were developed for enhanced butyric acid production by Clostridium tyrobutyricum. First, a novel fibrous-bed bioreactor (FBB) was developed for fermentation of glucose and xylose to produce butyrate with high reactor productivity (>2.5 g/L/h), high butyrate concentration (58 g/L), and a butyrate yield of 0.47 g/g. Cells in the FBB were able to grow into high density (>70 g/L) and tolerate high ...

Clostridium difficile is the most prevalent pathogen among all healthcare-associated infections. This anaerobic bacterium can colonize the human gut, typically following agents that disrupt the normal gut microbiota, like antibiotics. In the gut, C. difficile is subjected to oxygen, which it has to eliminate for survival. Its genome encodes for two flavodiiron proteins, capable to reduce oxygen to water. Besides, some FDPs also reduce NO to N2O, an important feature as a resistance mechanism towards the human innate immune system [1,2]. Flavodiiron enzymes are constituted by a minimal core of two domains: a metallo-β-lactamase-like one, harboring the catalytic center, followed by a short-chain flavodoxin [1,2]. More complex FDPs exist, with multiple extra domains and redox centers [1,2]. C. difficile contains a classical FDP, and a very complex one, with an extra short-type rubredoxin domain followed by an NADH:rubredoxin oxidoreductase-like one [3]. The biochemical, redox and spectroscopic studies

Production of Acetone, Butanol, and Ethanol (ABE) by Clostridium acetobutylicum YM1 from Pretreated Palm Kernel Cake in Batch Culture Fermentation
The first crystal structures of a two-domain, prokaryotic glucoamylase were determined to high resolution from the clostridial species Thermoanaerobacterium thermosaccharolyticum with and without acarbose. The N-terminal domain has 18 antiparallel strands arranged in beta-sheets of a super-beta-sandwich. The C-terminal domain is an (alpha/alpha)(6) barrel, lacking the peripheral subdomain of eukaryotic glucoamylases. Interdomain contacts are common to all prokaryotic Family GH15 proteins. Domains similar to those of prokaryotic glucoamylases in maltose phosphorylases (Family GH65) and glycoaminoglycan lyases (Family PL8) suggest evolution from a common ancestor. Eukaryotic glucoamylases may have evolved from prokaryotic glucoamylases by the substitution of the N-terminal domain with the peripheral subdomain and by the addition of a starch-binding domain.

In order to get basic results which allow the phylogenetic localisation and identification of Clostridium chauvoei and the closely related species Clostridium septicum, we cloned and sequenced the rrs genes encoding the 16SrRNA for these species and determined their phylogenetic position in Clostridium cluster I (C. carnis, C. perfringens, C. botulinum, C. tetani). Based on DNA sequence data, we developed an identification system for C. chauvoei, using specific PCR amplification of the rrs gene with specific oligonucleotids. ... The developed identification system was evaluated on clinical material during a recent outbreak of blackleg. Thereby C. chauvoei was identified as the etiological agent of the outbreak either directly from clinical samples of muscle, liver spleen and kidney or from primary cultures made with this material ...
Looks like there is more than one fount for male steroid hormones in the body. In a paper recently out in the Journal of Lipid Research, researchers show that a bacterial species converts glucocorticoids into androgens, a group of male steroid hormones. The implication is that the host endocrine system may not be the only source of androgens and other regulatory molecules: The gut microbiome may be another.. Phillip Hylemon at the Virginia Commonwealth University explains that there has been evidence since the 1960s that secondary bile acids, which are microbial products made from the primary bile acids secreted by the gallbladder, are associated with gastrointestinal diseases, such as colon cancer and cholesterol gallstones. "A small number of microbes inhabiting the (gastrointestinal) tract are the sole source of these molecules," he explains.. His group and others have worked out how the bacterium Clostridium scindens carries out the primary to secondary bile acid transformation. But it turns ...

In the UK and Netherlands scientists have genetically engineered an enzyme into the Clostridium sporogenes bacteria to deliver a cancer drug into anaerobic brain tumors. If their work continues to demonstrate success, this bacteria will be used to transport anti-cancer agents into previously inaccessible forms of cancer. The findings of this group will be presented at the annual meeting of the Society of Microbiology at the UKs University of York. Key to the findings of the group is that the use of this bacteria as a drug delivery system appears to leave healthy tissue surrounding tumors unharmed, in contrast to both chemotherapy and radiation treatment. This in and of itself is a milestone in cancer therapy.. Meanwhile, according to findings reported in the American Chemical Society (ACS), a compound called chlorotoxin from the highly poisonous venom of the deathstalker scorpion Leiurus quinquestriatus may also help to deliver anti-cancer genes to glioma, the most common and serious form of ...

Clostridium difficile is a Gram-positive spore-forming anaerobic bacillus found in the environment. Its spores are part of the colonic flora in about 2 to 3% of healthy adults, with colonization rates increasing during hospitalization to 20 to 40%. Disease occurs when the organism shifts to its replicating vegetative form with toxin (A and B) production, this typically happening when there is inhibition of the competing colonic flora by antibiotics. ...
