Clostridium perfringens: The most common etiologic agent of GAS GANGRENE. It is differentiable into several distinct types based on the distribution of twelve different toxins.Clostridium: A genus of motile or nonmotile gram-positive bacteria of the family Clostridiaceae. Many species have been identified with some being pathogenic. They occur in water, soil, and in the intestinal tract of humans and lower animals.Clostridium Infections: Infections with bacteria of the genus CLOSTRIDIUM.Clostridium difficile: A common inhabitant of the colon flora in human infants and sometimes in adults. It produces a toxin that causes pseudomembranous enterocolitis (ENTEROCOLITIS, PSEUDOMEMBRANOUS) in patients receiving antibiotic therapy.Gas Gangrene: A severe condition resulting from bacteria invading healthy muscle from adjacent traumatized muscle or soft tissue. The infection originates in a wound contaminated with bacteria of the genus CLOSTRIDIUM. C. perfringens accounts for the majority of cases (over eighty percent), while C. noyvi, C. septicum, and C. histolyticum cause most of the other cases.Enterotoxemia: Disease caused by the liberation of exotoxins of CLOSTRIDIUM PERFRINGENS in the intestines of sheep, goats, cattle, foals, and piglets. Type B enterotoxemia in lambs is lamb dysentery; type C enterotoxemia in mature sheep produces "struck", and in calves, lambs and piglets it produces hemorrhagic enterotoxemia; type D enterotoxemia in sheep and goats is pulpy-kidney disease or overeating disease.Bacterial Toxins: Toxic substances formed in or elaborated by bacteria; they are usually proteins with high molecular weight and antigenicity; some are used as antibiotics and some to skin test for the presence of or susceptibility to certain diseases.Enterotoxins: Substances that are toxic to the intestinal tract causing vomiting, diarrhea, etc.; most common enterotoxins are produced by bacteria.Clostridium botulinum: A species of anaerobic, gram-positive, rod-shaped bacteria in the family Clostridiaceae that produces proteins with characteristic neurotoxicity. It is the etiologic agent of BOTULISM in humans, wild fowl, HORSES; and CATTLE. Seven subtypes (sometimes called antigenic types, or strains) exist, each producing a different botulinum toxin (BOTULINUM TOXINS). The organism and its spores are widely distributed in nature.Spores, Bacterial: Heat and stain resistant, metabolically inactive bodies formed within the vegetative cells of bacteria of the genera Bacillus and Clostridium.Foodborne Diseases: Acute illnesses, usually affecting the GASTROINTESTINAL TRACT, brought on by consuming contaminated food or beverages. Most of these diseases are infectious, caused by a variety of bacteria, viruses, or parasites that can be foodborne. Sometimes the diseases are caused by harmful toxins from the microbes or other chemicals present in the food. Especially in the latter case, the condition is often called food poisoning.Enteritis: Inflammation of any segment of the SMALL INTESTINE.Claudin-4: A claudin subtype that takes part in maintaining the barrier-forming property of TIGHT JUNCTIONS. Claudin-4 is found associated with CLAUDIN-8 in the KIDNEY COLLECTING DUCT where it may play a role in paracellular chloride ion reabsorption.Clostridium tetani: The cause of TETANUS in humans and domestic animals.

It is commonly associated with antibiotic therapy and CLOSTRIDIUM DIFFICILE colonization.Toxins, Biological: Specific, characterizable, poisonous chemicals, often PROTEINS, with specific biological properties, including immunogenicity, produced by microbes, higher plants (PLANTS, TOXIC), or ANIMALS.Type C Phospholipases: A subclass of phospholipases that hydrolyze the phosphoester bond found in the third position of GLYCEROPHOSPHOLIPIDS. Although the singular term phospholipase C specifically refers to an enzyme that catalyzes the hydrolysis of PHOSPHATIDYLCHOLINE (EC 3.1.4.3), it is commonly used in the literature to refer to broad variety of enzymes that specifically catalyze the hydrolysis of PHOSPHATIDYLINOSITOLS.Claudin-3: A ubiquitously-expressed claudin subtype that acts as a general barrier-forming protein in TIGHT JUNCTIONS. Elevated expression of claudin-3 is found in a variety of tumor cell types, suggesting its role as a therapeutic target for specific ANTINEOPLASTIC AGENTS.Food Microbiology: The presence of bacteria, viruses, and fungi in food and food products. This term is not restricted to pathogenic organisms: the presence of various non-pathogenic bacteria and fungi in cheeses and wines, for example, is included in this concept.Feces: Excrement from the INTESTINES, containing unabsorbed solids, waste products, secretions, and BACTERIA of the DIGESTIVE SYSTEM.Spores: The reproductive elements of lower organisms, such as BACTERIA; FUNGI; and cryptogamic plants.Clostridium acetobutylicum: A species of gram-positive bacteria in the family Clostridiaceae, used for the industrial production of SOLVENTS.ADP Ribose Transferases: Enzymes that transfer the ADP-RIBOSE group of NAD or NADP to proteins or other small molecules. Transfer of ADP-ribose to water (i.e., hydrolysis) is catalyzed by the NADASES. The mono(ADP-ribose)transferases transfer a single ADP-ribose. POLY(ADP-RIBOSE) POLYMERASES transfer multiple units of ADP-ribose to protein targets, building POLY ADENOSINE DIPHOSPHATE RIBOSE in linear or branched chains.Botulinum Toxins: Toxic proteins produced from the species CLOSTRIDIUM BOTULINUM. The toxins are synthesized as a single peptide chain which is processed into a mature protein consisting of a heavy chain and light chain joined via a disulfide bond. The botulinum toxin light chain is a zinc-dependent protease which is released from the heavy chain upon ENDOCYTOSIS into PRESYNAPTIC NERVE ENDINGS. Once inside the cell the botulinum toxin light chain cleaves specific SNARE proteins which are essential for secretion of ACETYLCHOLINE by SYNAPTIC VESICLES. This inhibition of acetylcholine release results in muscular PARALYSIS.Clostridium thermocellum: A species of gram-positive, thermophilic, cellulolytic bacteria in the family Clostridaceae. It degrades and ferments CELLOBIOSE and CELLULOSE to ETHANOL in the CELLULOSOME.Bacterial Proteins: Proteins found in any species of bacterium.Antitoxins: Antisera from immunized animals that is purified and used as a passive immunizing agent against specific BACTERIAL TOXINS.Clostridium septicum: A species of gram-positive bacteria in the family Clostridiaceae.

Sandwich enzyme-linked immunosorbent assay by using monoclonal antibody for detection of Clostridium perfringens enterotoxin. (1/1215)

Sandwich enzyme-linked immunosorbent assay (ELISA) was developed for the quantitative estimation of Clostridium perfringens enterotoxin (CPE) with monoclonal and polyclonal antibodies as capturing and detecting antibodies, respectively. The dose-dependent relationship between absorbance at 405 nm and concentration of purified CPE was obtained over the range of 0.64-400 ng/ml. The sandwich ELISA was fond to detect crude CPE in culture and CPE in 10% fecal extracts. This method is convenient, rapid and sensitive for specific detection of CPE.  (+info)

Hemorrhagic enteritis associated with Clostridium perfringens type A in a dog. (2/1215)

A female Shetland sheep dog died suddenly with hemorrhagic diarrhea and vomitting, and was examined pathologically and microbiologically. Gross pathological change was restricted to the intestinal tract. The intestine contained watery, blood-stained fluid. Histopathologically, the principal intestinal lesion was superficial mucosal hemorrhagic necrosis at the jejunoileum. Many Gram-positive bacilli were found adhering to the necrotic mucosal surface in parts of the intestinal tract. Clostridium perfringens in pure culture were isolated from jejunal contents by anaerobic culture. These results suggested that the typical lesion of this case coincided with canine hemorrhagic enteritis and enterotoxemia due to C. perfringens infection could be the cause of sudden death.  (+info)

Cationic currents induced by Clostridium perfringens type A enterotoxin in human intestinal CaCO-2 cells. (3/1215)

Clostridium perfringens type A produces an enterotoxin that induces diarrhoea experimentally in man and animals. The enterotoxin causes increased membrane permeability in susceptible cells which is thought to be due to pore formation in the host cell membrane. The effect of purified C. perfringens enterotoxin on intact intestinal CaCO-2 monolayers was examined in Ussing chambers and on single cells by whole-cell patch clamp. Mucosal application of C. perfringens enterotoxin resulted in prompt increases in short-circuit current coupled with a reduction in transepithelial resistance consistent with movement of sodium and other cations smaller than diethanolamine from mucosa to serosa. These changes were independent of extracellular calcium. Increases in short-circuit current were also observed in the apical membranes of CaCO-2 monolayers permeabilised across the basolateral membrane with nystatin. Currents were blocked by subsequent exposure to mucosal barium and zinc. Zinc also prevented the development of the current increases in apical membranes. Cationic currents were also observed following exposure of single CaCO-2 cells in whole-cell patch clamp recordings. These data indicate that C. perfringens enterotoxin is able to form cation permeant pores in the apical membrane of human intestinal CaCO-2 epithelia and the increases in short-circuit current can be prevented by pre-exposure to zinc ions.  (+info)

Production of phospholipase C (alpha-toxin), haemolysins and lethal toxins by Clostridium perfringens types A to D. (4/1215)

To obtain high yields of extracellular enzymes and toxins for immunological analysis, type culture collection strains of Clostridium perfringens types A to D and 28 fresh isolates of C. perfringens type A from humans were grown in fermenters under controlled conditions in a pre-reduced proteose peptone medium. The type culture collection strains all showed different characteristics with respect to growth rates and pH optima for growth. Production of phospholipase C (alpha-toxin), haemolysin and lethal activity varied considerably between the different types. Growth and extracellular protein production in fermenters with pH control and static or stirred cultures were compared. Production of all extracellular proteins measured was markedly improved by cultivation in fermenters with pH control. Strain ATCC13124 produced five times more phospholipase C than any of 28 freshly isolated strains of C. perfringens type A, grown under identical conditions. Haemolytic and lethal activities of the ATCC strain were equal or superior to the activities of any of the freshly isolated strains. There were no differences in the bacterial yields and in the production of extracellular toxins between type A strains isolated from clinical cases of gas gangrene and abdominal wounds, and those isolated from faecal samples from healthy persons.  (+info)

Clostridium perfringens beta-toxin is sensitive to thiol-group modification but does not require a thiol group for lethal activity. (5/1215)

The beta-toxin gene isolated from Clostridium perfringens type B was expressed as a glutathione S-transferase (GST) fusion gene in Escherichia coli. The purified GST-beta-toxin fusion protein from the E. coli transformant cells was not lethal. The N-terminal amino acid sequence of the recombinant beta-toxin (r toxin) isolated by thrombin cleavage of the fusion protein was G-S-N-D-I-G-K-T-T-T. Biological activities and molecular mass of r toxin were indistinguishable from those of native beta-toxin (n toxin) purified from C. perfringens type C. Replacement of Cys-265 with alanine or serine by site-directed mutagenesis resulted in little loss of the activity. Treatment of C265A with N-ethylmaleimide (NEM), which inactivated lethal activity of r toxin and n toxin, led to no loss of the activity. The substitution of tyrosine or histidine for Cys-265 significantly diminished lethal activity. In addition, treatment of C265H with ethoxyformic anhydride which specifically modifies histidyl residue resulted in significant decrease in lethal activity, but that of r toxin with the agent did not. These results showed that replacement of the cysteine residue at position 265 with amino acids with large size of side chain or introduction of functional groups in the position resulted in loss of lethal activity of the toxin. Replacement of Tyr-266, Leu-268 or Trp-275 resulted in complete loss of lethal activity. Simultaneous administration of r toxin and W275A led to a decrease in lethal activity of beta-toxin. These observations suggest that the site essential for the activity is close to the cysteine residue.  (+info)

Molecular subtyping of Clostridium perfringens by pulsed-field gel electrophoresis to facilitate food-borne-disease outbreak investigations. (6/1215)

Clostridium perfringens is a common cause of food-borne illness. The illness is characterized by profuse diarrhea and acute abdominal pain. Since the illness is usually self-limiting, many cases are undiagnosed and/or not reported. Investigations are often pursued after an outbreak involving large numbers of people in institutions, at restaurants, or at catered meals. Serotyping has been used in the past to assist epidemiologic investigations of C. perfringens outbreaks. However, serotyping reagents are not widely available, and many isolates are often untypeable with existing reagents. We developed a pulsed-field gel electrophoresis (PFGE) method for molecular subtyping of C. perfringens isolates to aid in epidemiologic investigations of food-borne outbreaks. Six restriction endonucleases (SmaI, ApaI, FspI, MluI, KspI, and XbaI) were evaluated with a select panel of C. perfringens strains. SmaI was chosen for further studies because it produced 11 to 13 well-distributed bands of 40 to approximately 1,100 kb which provided good discrimination between isolates. Seventeen distinct patterns were obtained with 62 isolates from seven outbreak investigations or control strains. In general, multiple isolates from a single individual had indistinguishable PFGE patterns. Epidemiologically unrelated isolates (outbreak or control strains) had unique patterns; isolates from different individuals within an outbreak had similar, if not identical, patterns. PFGE identifies clonal relationships of isolates which will assist epidemiologic investigations of food-borne-disease outbreaks caused by C. perfringens.  (+info)

Promoter upstream bent DNA activates the transcription of the Clostridium perfringens phospholipase C gene in a low temperature-dependent manner. (7/1215)

The phospholipase C gene (plc) of Clostridium perfringens possesses three phased A-tracts forming bent DNA upstream of the promoter. An in vitro transcription assay involving C.perfringens RNA polymerase (RNAP) showed that the phased A-tracts have a stimulatory effect on the plc promoter, and that the effect is proportional to the number of A-tracts, and more prominent at lower temperature. A gel retardation assay and hydroxyl radical footprinting revealed that the phased A-tracts facilitate the formation of the RNAP-plc promoter complex through extension of the contact region. The upstream (UP) element of the Escherichia coli rrnB P1 promoter stimulated the downstream promoter activity temperature independently, differing from the phased A-tracts. When the UP element was placed upstream of the plc promoter, low temperature-dependent stimulation was observed, although this effect was less prominent than that of the phased A-tracts. These results suggest that both the phased A-tracts and UP element cause low temperature-dependent activation of the plc promoter through a similar mechanism, and that the more efficient low temperature-dependent activation by the phased A-tracts may be due to an increase in the bending angle at a lower temperature.  (+info)

Differences in the carboxy-terminal (Putative phospholipid binding) domains of Clostridium perfringens and Clostridium bifermentans phospholipases C influence the hemolytic and lethal properties of these enzymes. (8/1215)

The phospholipases C of C. perfringens (alpha-toxin) and C. bifermentans (Cbp) show >50% amino acid homology but differ in their hemolytic and toxic properties. We report here the purification and characterisation of alpha-toxin and Cbp. The phospholipase C activity of alpha-toxin and Cbp was similar when tested with phosphatidylcholine in egg yolk or in liposomes. However, the hemolytic activity of alpha-toxin was more than 100-fold that of Cbp. To investigate whether differences in the carboxy-terminal domains of these proteins were responsible for differences in the hemolytic and toxic properties, a hybrid protein (NbiCalpha) was constructed comprising the N domain of Cbp and the C domain of alpha-toxin. The hemolytic activity of NbiCalpha was 10-fold that of Cbp, and the hybrid enzyme was toxic. These results confirm that the C-terminal domain of these proteins confers different properties on the enzymatically active N-terminal domain of these proteins.  (+info)

Clostridium perfringens beta toxin is one of the four major lethal toxins produced by Clostridium perfringens Type B and Type C strains. It is a necrotizing agent and it induces hypertension by release of catecholamine. It has been shown to cause necrotic enteritis in mammals and induces necrotizing intestinal lesions in the rabbit ileal loop model. C. perfringens beta toxin is susceptible to breakdown by proteolytic enzymes, particularly trypsin. Beta toxin is therefore highly lethal to infant mammals because of trypsin inhibitors present in the colostrum. Clostridium perfringens beta toxin shows significant genetic homology with several other toxins. C. perfringens beta toxin shows 28% homology with S. aureus alpha toxin and similar homology to S. aureus gamma-toxin and leukocidin. It appears in two forms. The smaller, with a molecular mass of 34 kDa, represents the monomeric gene product. The larger has a molecular mass of 118 kDa and may be an oligomer of smaller units. The first 27 amino ...

Clostridium perfringens type A is a common source of foodborne illness (FBI) in humans. Vegetative cells sporulate in the small intestinal tract and produce the major pathogenic factor C. perfringens enterotoxin. Although sporulation plays a critical role in the pathogenesis of FBI, the mechanisms inducing sporulation remain unclear. Bile salts were shown previously to induce sporulation, and we confirmed deoxycholate (DCA)-induced sporulation in C. perfringens strain NCTC8239 cocultured with human intestinal epithelial Caco-2 cells. In the present study, we performed transcriptome analyses of strain NCTC8239 in order to elucidate the mechanism underlying DCA-induced sporulation. Of the 2,761 genes analyzed, 333 were up- or downregulated during DCA-induced sporulation and included genes for cell division, nutrient metabolism, signal transduction, and defense mechanisms. In contrast, the virulence-associated transcriptional regulators (the VirR/VirS system, the agr system, codY, and abrB) were ...
The entire human body and its many compartments are shielded from their external environments by the barrier function of epithelial cell sheets. The paracellular barrier function of tight junctions (TJs) is critical for maintaining homeostasis in any multicellular organism, especially in the skin and internal organs and at the blood-brain barrier. One of the major components of TJs is a family of adhesive membrane proteins known as claudins. Several members of the claudin family are receptors for the bacterial toxin Clostridium perfringens enterotoxin. This toxin often causes food-borne illness both in humans and animals. Saitoh et al. crystallized a complex between the toxin and a claudin that reveals just how the toxin damages epithelial barriers (see the Perspective by Artursson and Knight)..

The ability of Clostridium perfringens to form spores plays a key role during the transmission of this Gram-positive bacterium to cause disease. Of particular note, the spores produced by food poisoning strains are often exceptionally resistant to food environment stresses such as heat, cold, and preservatives, which likely facilitates their survival in temperature-abused foods. The exceptional resistance properties of spores made by most type A food poisoning strains and some type C foodborne disease strains involve their production of a variant small acid-soluble protein-4 that binds more tightly to spore DNA than to the small acid-soluble protein-4 made by most other C. perfringens strains. Sporulation and germination by C. perfringens and Bacillus spp. share both similarities and differences. Finally, sporulation is essential for production of C. perfringens enterotoxin, which is responsible for the symptoms of C. perfringens type A food poisoning, the second most common bacterial foodborne disease
DESCRIPTION (provided by applicant): C. perfringens epsilon-toxin (ETX) is a potential biological weapon included in the list of category B priority agents. The overall goal of this proposal is to identify and perform in vivo testing of new inhibitors of E TX using a novel approach for the inactivation of pore-forming toxins developed at Innovative Biologics, Inc. It is based on the blocking of the target pore with molecules having the same symmetry as the pore itself. Results from our SBIR Phase I project d emonstrated that beta-cyclodextrin derivatives designed to block the transmembrane channel formed by epsilon-toxin can inhibit its cytotoxicity at low micromolar concentrations. Based on the successful completion of this feasibility study, we propose to de sign, synthesize and screen a library of beta-cyclodextrin derivatives for inhibitors of epsilon-toxins activity and test selected lead compounds in mice. The specific aims of this Phase II study are: (1) Optimize the assay for testing ...
MORRIS, W. E. y FERNANDEZ-MIYAKAWA, M. E.. Toxins of Clostridium perfringens. Rev. argent. microbiol. [online]. 2009, vol.41, n.4, pp. 251-260. ISSN 1851-7617.. Clostridium perfringens is an anaerobic gram-positive spore-forming bacillus. It is one of the pathogens with larger distribution in the environment; it can be isolated from soil and water samples, which also belongs to the intestinal flora of animals and humans. However, on some occasions it can act as an opportunistic pathogen, causing diseases such as gas gangrene, enterotoxemia in sheep and goats and lamb dysentery, among others. In human beings, it is associated to diseases such as food poisoning, necrotic enterocolitis of the infant and necrotic enteritis or pigbel in Papua-New Guinea tribes. The renewed interest existing nowadays in the study of C. perfringens as a veterinarian and human pathogen, together with the advance of molecular biology, had enabled science to have deeper knowledge of the biology and pathology of these ...

The Gram-positive pathogen Clostridium perfringens possesses a family of large conjugative plasmids that is typified by the tetracycline resistance plasmid pCW3. Since these plasmids may carry antibiotic resistance genes or genes encoding extracellular or sporulation-associated toxins, the conjugative transfer of these plasmids appears to be important for the epidemiology of C. perfringens-mediated diseases. Sequence analysis of members of this plasmid family identified a highly conserved 35kb region that encodes proteins with various functions, including plasmid replication and partitioning. The tcp conjugation locus also was identified in this region, initially based on low-level amino acid sequence identity to conjugation proteins from the integrative conjugative element Tn916. Genetic studies confirmed that the tcp locus is required for conjugative transfer and combined with biochemical and structural analyses have led to the development of a functional model of the Tcp conjugation ...
As mentioned in our introduction, the availability of CPE-directed therapeutics could be helpful for ameliorating several CPE-associated medical conditions. A previous study had suggested that the drug mepacrine might be a candidate CPE therapeutic because the presence of this drug interferes with CPE-induced electrophysiologic activity in artificial lipid bilayers (24). However, that study did not distinguish whether mepacrine inactivates the CPE protein or instead interferes with some step in CPE action, i.e., whether this drug affects CPE binding, CPE pore formation, or CPE pore activity. Furthermore, it was specifically important to determine whether mepacrine is not only protective against CPE electrophysiologic activity in artificial membranes but also inhibits CPE-induced cytotoxicity in mammalian cells, where receptors are present and complex phenomena like membrane vesicle release occur (30).. Therefore, a first major contribution of the current study entailed demonstrating that ...
Clostridium perfringens, is an anaerobic, gram-positive, pathogenic and spore-forming bacillus and broadly gave out in our territory. This bacterium has spore formation capability and creating gangrene and gastrointestinal disease, for example food poisoning and necrotic enteritis in human, whilst in other animals, gastrointestinal and enterotoxemic diseases more happening. Prevalence of necrotic enteritis, created by C. perfringens, has been often stated in sheep, chickens and ostrich throughout the world. The most critical problem for epidemiological investigations and vaccines improvement is accurate recognition of C. perfringens variants. Moreover, Small ruminants, especially native breed types, play an important role to the livelihoods of a considerable part of human population in the tropics from socio-economic aspects. Therefore, integrated attempt in terms of management and genetic improvement to enhance production is of crucial importance. Poultry provide humans with companionship, food ...
Necrotic enteritis toxin B (NetB) is a β-pore-forming toxin produced by Clostridium perfringens and has been identified as a key virulence factor in the pathogenesis of avian necrotic enteritis, a disease causing significant economic damage to the poultry industry worldwide. In this study, site-directed mutagenesis was used to identify amino acids that play a role in NetB oligomerisation and pore-formation. NetB K41H showed significantly reduced toxicity towards LMH cells and human red blood cells relative to wild type toxin. NetB K41H was unable to oligomerise and form pores in liposomes. These findings suggest that NetB K41H could be developed as a genetic toxoid vaccine to protect against necrotic enteritis.

Interpretive Summary: Clostridium perfringens is recognized as an enteric bacterial pathogen in humans, poultry, other domestic animals and wildlife. It has been isolated from processed broilers and the processing plant and is reported to be a major cause of human outbreaks from poultry. This study demonstrated that C. perfringens is transmitted between facilities (breeder farm, hatchery, previous grow-out flock) within the integrated commercial broiler operation. Technical Abstract: Clostridium perfringens has been shown to be widespread in the broiler chicken hatchery, grow-out, and processing operations. In a previous study, ribotypes of certain strains of C. perfringens isolated from processed chicken carcasses were shown to match ribotypes isolated from paper pad lining trays used to transport ...

An aerobic biofilter system was studied to assess its effectiveness for reducing enteric microbial indicators in flushed swine wastewater under different seasonal conditions. A laboratory-scale, low-pressure UV collimated beam apparatus was used to investigate the effectiveness of UV irradiation for inactivating enteric bacteria, coliphages, and bacterial spores in treated and untreated swine wastewater having unfiltered absorbances of 5 to 11 cm−1 and total suspended solids concentrations of 500 to 1200 mg/L. Fecal coliforms, Escherichia coli, enterococci, somatic coliphages, and male-specific coliphages were reduced by 97 to 99% in the biofilter system when reactor water temperatures were between 23 and 32 °C. Salmonella were reduced by 95 to 97% when water temperatures were 17 to 32 °C. Of the six microbial indicators studied, Clostridium perfringens spores were typically reduced the least by the biofilter system. At an average absorbed UV irradiation dose of 13 mJ/cm 2 , maximum ...
Infectious diarrhoea in dogs and cats is one of the most common maladies facing small animal veterinarians today, but the role of enteropathogenic bacteria is poorly understood. Clostridium perfringens, C. difficile, Campylobacter spp., and Salmonella spp. are four of the most commonly incriminated enteropathogenic bacteria in canine and feline diarrhoea;1,2,3 however, the clinical documentation of these bacteria in dogs and cats is clouded by their presence as normal constituents of the indigenous intestinal microflora in many animals. The indications for performing faecal enteric panels on diarrhoeic dogs and cats are poorly defined, resulting in indiscriminate testing, and misinterpretation of results.. Clostridium perfringens. Clostridium perfringens is an anaerobic, spore-forming, gram-positive bacillus that has been associated with outbreaks of acute, often severe diarrhoea in humans, horses, dogs, and cats. The elaboration of four major toxins (α, β, ι, and ε) is the basis for typing ...
Clostridium perfringens is a spore-forming bacterium which commonly presents in raw meat and poultry. Outbreaks of Clostridium perfringens often happen when food is prepared in large quantities and kept under inappropriate holding temperature for a prolonged period. Preventive measures include thorough cooking of food and keeping food at the safe temperatures, i.e. above 60˚C or at or below 4˚C.. In June 2014, the CFS was informed of a major food poisoning case involving 93 school children. Epidemiological information revealed that the incriminated lunch boxes suspected to be contaminated with Clostridium perfringens were provided by a food factory. Investigation revealed that improper holding temperature of the lunch box meals during transport from the food factory to school for seven hours or more was suspected to be the contributing factor leading to food poisoning. The CFS instructed the food factory to follow good food safety practices, particularly keeping the lunch boxes at proper ...
Clostridium perfringens is an anaerobic bacterium that causes numerous important human and animal diseases, primarily as a result of its ability to produce many different protein toxins. In chickens, C. perfringens causes necrotic enteritis, a disease of economic importance to the worldwide poultry industry. The secreted pore-forming toxin NetB is a key virulence factor in the pathogenesis of avian necrotic enteritis and is similar to alpha-hemolysin, a beta-barrel pore-forming toxin from Staphylococcus aureus. To address the molecular mechanisms underlying NetB-mediated tissue damage, we determined the crystal structure of the monomeric form of NetB to 1.8 A. Structural comparisons with other members of the alpha-hemolysin family revealed significant differences in the conformation of the membrane binding domain. These data suggested that NetB may recognize different membrane receptors or use a different mechanism for membrane-protein interactions. Consistent with this idea, ...

The protein encoded by this intronless gene belongs to the claudin family. Claudins are integral membrane proteins that are components of the epithelial cell tight junctions, which regulate movement of solutes and ions through the paracellular space. This protein is a high-affinity receptor for Clostridium perfringens enterotoxin (CPE) and may play a role in internal organ development and function during pre- and postnatal life. This gene is deleted in Williams-Beuren syndrome, a neurodevelopmental disorder affecting multiple systems. [provided by RefSeq, Sep 2013 ...

Some pathogenic species of Clostridium employ the classic enzymatic "AB" binary protein toxins for poisoning cells. Clostridium perfringens, C. difficile, C. spiroforme, and C. botulinum all use similar binary toxins (iota toxin (Ia and Ib), CDT (CDTa and CDTb), CST (CSTa and CSTb), and C2 toxin (C2I and C2II), respectively). They consist of the enzymatic A component, an actin-specific ADP-ribosyltransferase and the B component that binds to the host cell and forms a membrane-spanning pore that functions as the translocation channel for each enzymatic component. The B component translocates the A component into the host cell via the membrane in the acidic endosome. In contrast, the Bacillus anthracis species uses a different binary toxin, which consists of two enzymatic proteins: the lethal (LF) and edema (EF) factors, and a protein translocation channel, PA. The PA heptameric pore structure was revealed to have extremely narrow φ-clamp passageway and a long membrane-spanning channel. ...

Clostridium perfringens (formerly known as C. welchii) is a Gram-positive, rod-shaped, anaerobic, spore-forming bacterium of the genus Clostridium. It is always present in nature and is a normal component of decaying vegetation, marine sediment, the intestinal tract of humans, other vertebrates, insects, and soil. It can be a human pathogen and also harmlessly ingested. Commonly it is encountered in infections as a component of the normal flora where it takes a minor role in the disease. Infections show some evidence of tissue necrosis, bacteremia, emphysematous cholecystitis, and gas gangrene, which is also known as clostridial myonecrosis. The toxin in gas gangrene is α-toxin which inserts into the plasma membrane of cells disrupting normal cellular function C. perfringens. Ingestion can lead to bacteria multiplying and leading to colic, diarrhea, and sometimes nausea. C. perfringens bacteria are the third-most-common cause of food-borne illness, with poorly prepared meat and poultry the ...

A coprological survey with detailed clinical observation of naturally occurring haemorrhagic enteritis (HE) cases was conducted to understand the pathophysiology of HE by clarifying the infection status of Eimeria and enteropathogenic bacteria in cattle. Faecal samples from 55 cases of HE and 26 clinically normal animals were collected, and a quantitative examination of Eimeria and potential enteropathogenic bacteria was performed. The number of Eimeria species oocysts per gram of faeces (OPG) exceeded 10,000 in 69.1 per cent of HE cases with a maximum of 1,452,500 OPG and Eimeria zuernii was found to be overwhelmingly dominant. A significant increase in faecal coliform count was observed in HE cases compared with clinically normal animals. Among the animals shedding ,10,000 OPG, 42.9 per cent showed a remarkable increase in Clostridium perfringens abundance (,104 CFU/g) in the faeces. In the cases with C. perfringens detected, its abundance was positively correlated with Eimeria OPG and high C. ...

Spore-forming bacteria are the causative agents of some of the most dramatic life-threatening human and animal infections and toxemias, including diseases such as tetanus, botulism, gas gangrene, pseudomembranous colitis, and anthrax. This chapter reviews the current state of knowledge of virulence plasmids of the Clostridia and the bacilli. Although other pathogens are mentioned, the focus is on the major human pathogens, Clostridium perfringens and Bacillus anthracis, primarily because most is known about virulence plasmids in these species. The major toxins involved in C. perfringens type A-mediated gas gangrene, the α-toxin and perfringolysin O, together with other extracellular toxins such as collagenase and hyaluronidase, are chromosomally encoded. Along with tetanus, botulism, and gas gangrene, anthrax is one of the four classical diseases that are caused by spore-forming bacteria. Expression of the plasmid-determined toxin genes in Bacillus thuringiensis is coordinately regulated with the
Claudin-4 (Clostridium perfringens enterotoxin receptor) is a tight junction protein encoded by the gene CLDN4. Expression of Claudin-4 has been associated with either poor prognosis or a more favorable diagnosis, depending on the type of cancer. Claudin-4 has been shown to distinguish adenocarcinoma from malignant mesothelioma with 99% specificity in malignant effusions (1). Claudin-4 overexpression was able to independently predict survival in a breast cancer multivariate analysis as it was associated with poor prognosis, high tumor grade and Her2 expression and was inversely correlated with estrogen receptor staining (2). In luminal breast cancer, the increase of Claudin-4 protein was correlated with the increase of tumor grade and with Ki-67, and thus demonstrated an overall shorter life survival (3). Basal-like tumors also demonstrated overexpression of Claudin-4 (4). Counter to the above breast cancer subtypes, the presence of Claudin-4 in triple negative breast cancer was a biomarker that

This work was carried out in two phases. The first was to examine the effect that the cereals, wheat and corn and their major components have on the in vitro proliferation and alpha toxin production by Clostridium perfringens type A (CP). The second phase was to determine the prevalence of CP in broiler chickens in Saskatchewan and finally, what factors may be involved for the increased susceptibility of broilers on farms to CP, and what consequences to the production cycle affected flocks may have when infected with CP. In the first experiment, CP was grown in vitro in thioglycollate media (TG) alone, TG plus pancreatin and pepsin (TGE) or TG plus in vitro digested corn (C) or wheat (W) supernatant in a 2:1 ratio. Colony forming units (CFU) were counted and alpha toxin activity (U) was measured from each group using a commercially available kit. There was significantly more proliferation when CPA was grown in W compared to C, TG, or TGE. Alpha toxin production was significantly higher in C ...

An improved method is described for preparing the enzyme which hydrolyzes the polysaccharide acid contained in vitreous humor, umbilical cord, synovial fluid, and the mucoid phase of group A hemolytic streptococci.. Preparations have been obtained from pneumococci, group A hemolytic streptococci, Clostridium welchii, and from splenic tissue, which display the same specific activity.. Evidence is presented to show that the hydrolytic enzyme is not the same as that responsible for the lysis of pneumococci.. In pneumococci and hemolytic streptococci the major portion of the enzyme is bound to the cell structure. The enzyme from Clostridium welchii is associated with other carbohydrate-splitting enzymes in the culture medium and not with the bacterial cells.. It is suggested that the disappearance of the mucoid capsule of group A hemolytic streptococci is due to enzymatic hydrolysis of the acid polysaccharide.. The relation between enzyme activity and the virulence and invasiveness of group A ...

Haemorrhagic enterotoxaemia caused by Cl. perfringens type C is a common disease in raising lambs and the main cause of economic losses during the first few weeks of life. It has been shown that vaccination of newborn lambs is not very effective in conferring protection and seroconversion produced is minimal. However, the transfer of antibodies via colostrum seems to be protective and detectable. The aim of this study was to evaluate the rate of passive immunization via colostrum from animals vaccinated with 2 commercial vaccines for preventing enterotoxaemia using a vaccination and revaccination schedule of ewes ante partum, compared with a control group.. ...
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 ...

INTRODUCTION: The resolution of pouchitis with metronidazole points to an anaerobic aetiology. Pouchitis is mainly seen in patients with ulcerative colitis pouches (UCP). We have recently found that sulphate reducing bacteria (SRB), a species of strict anaerobe, colonize UCP exclusively. Herein, we aimed to correlate levels of different bacterial species (including SRB) with mucosal inflammation and morphology. METHODS: Following ethical approval, fresh faecal samples and mucosal biopsies were taken from 9 patients with UCP and 5 patients with familial adenomatous polyposis pouches (FAPP). For the purposes of comparison, faecal samples and mucosal biopsies were also taken from the stomas of 7 of the 9 patients with UC (UCS). Colonization by four types of strict anaerobes (SRB, Clostridium perfringens, Bifidobacteria and Bacteroides) as well as by three types of facultative anaerobes (Enterococci, Coliforms and Lactobacilli) was evaluated. Inflammatory scores and mucosal morphology were assessed ...

Looking for online definition of clostridial necrotic enteritis in the Medical Dictionary? clostridial necrotic enteritis explanation free. What is clostridial necrotic enteritis? Meaning of clostridial necrotic enteritis medical term. What does clostridial necrotic enteritis mean?
Clostridium perfringens, the third most common cause of foodborne illness in the United States (1), most often causes a self-limited, diarrheal disease lasting 12-24 hours. Fatalities are very rare, occurring in ,0.03% of cases (1). Death usually is caused by dehydration and occurs among the very young, the very old, and persons debilitated by illness (2). On May 7, 2010, 42 residents and 12 staff members at a Louisiana state psychiatric hospital experienced vomiting, abdominal cramps, and diarrhea. Within 24 hours, three patients had died. The three fatalities occurred among patients aged 41-61 years who were receiving medications that had anti-intestinal motility side effects. For two of three decedents, the cause of death found on postmortem examination was necrotizing colitis. Investigation by the Louisiana Office of Public Health (OPH) and CDC found that eating chicken served at dinner on May 6 was associated with illness. The chicken was cooked approximately 24 hours before serving and not ...
Gas gangrene is a condition where anaerobic bacteria release toxins that cause tissue death, and if not treated can be fatal. Gas gangrene is typically an infection of muscle tissue and a characteristic sign of infection is the presence of blisters that bubble with gas near infected areas. There are fewer than 3,000 cases in the United States annually. In this article you will find out more about gas gangrene symptoms and whether there have been historical outbreaks of gas gangrene.
Gas gangrene is caused by exotoxin-producing Clostridium species (most often C. perfringens, and C. novyi,[5] but less commonly C. septicum[6] or C. ramnosum),[7] which are mostly found in soil, but also found as normal gut flora, and other anaerobes (e.g., Bacteroides and anaerobic streptococci). The exotoxin is commonly found in C. perfringens type A strain and is known as alpha toxin. This alpha toxin is a lethal toxin and also known as phospholipase C (lecithinase). It increases vascular permeability and produces necrotizing activity. These environmental bacteria may enter the muscle through a wound and go on to proliferate in necrotic tissue and secrete powerful toxins. These toxins destroy nearby tissue, generating gas at the same time.. Other organisms may occasionally cause gas gangrene (for example, Klebsiella pneumoniae in the context of diabetes).[8]. A gas composition of 5.9% hydrogen, 3.4% carbon dioxide, 74.5% nitrogen, and 16.1% oxygen was reported in one clinical ...
