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.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.Botulinum Toxins, Type A: A serotype of botulinum toxins that has specificity for cleavage of SYNAPTOSOMAL-ASSOCIATED PROTEIN 25.Neurotoxins: Toxic substances from microorganisms, plants or animals that interfere with the functions of the nervous system. Most venoms contain neurotoxic substances. Myotoxins are included in this concept.Botulism: A disease caused by potent protein NEUROTOXINS produced by CLOSTRIDIUM BOTULINUM which interfere with the presynaptic release of ACETYLCHOLINE at the NEUROMUSCULAR JUNCTION. Clinical features include abdominal pain, vomiting, acute PARALYSIS (including respiratory paralysis), blurred vision, and DIPLOPIA. Botulism may be classified into several subtypes (e.g., food-borne, infant, wound, and others). (From Adams et al., Principles of Neurology, 6th ed, p1208)Clostridium: A genus of motile or nonmotile gram-positive bacteria of the family Clostridiaceae.

Biodiversity of Clostridium botulinum type E strains isolated from fish and fishery products. (2/657)

The genetic biodiversity of Clostridium botulinum type E strains was studied by pulsed-field gel electrophoresis (PFGE) with two macrorestriction enzymes (SmaI-XmaI and XhoI) and by randomly amplified polymorphic DNA (RAPD) analysis with two primers (OPJ 6 and OPJ 13) to characterize 67 Finnish isolates from fresh fish and fishery products, 15 German isolates from farmed fish, and 10 isolates of North American or North Atlantic origin derived mainly from different types of seafood. The effects of fish species, processing, and geographical origin on the epidemiology of the isolates were evaluated. Cluster analysis based on macrorestriction profiles was performed to study the genetic relationships of the isolates. PFGE and RAPD analyses were combined and resulted in the identification of 62 different subtypes among the 92 type E isolates analyzed. High genetic biodiversity among the isolates was observed regardless of their source. Finnish and North American or North Atlantic isolates did not form distinctly discernible clusters, in contrast with the genetically homogeneous group of German isolates. On the other hand, indistinguishable or closely related genetic profiles among epidemiologically unrelated samples were detected. It was concluded that the high genetic variation was probably a result of a lack of strong selection factors that would influence the evolution of type E. The wide genetic biodiversity observed among type E isolates indicates the value of DNA-based typing methods as a tool in contamination studies in the food industry and in investigations of botulism outbreaks.  (+info)

Growth from spores of nonproteolytic Clostridium botulinum in heat-treated vegetable juice. (3/657)

Unheated spores of nonproteolytic Clostridium botulinum were able to lead to growth in sterile deoxygenated turnip, spring green, helda bean, broccoli, or potato juice, although the probability of growth was low and the time to growth was longer than the time to growth in culture media. With all five vegetable juices tested, the probability of growth increased when spores were inoculated into the juice and then heated for 2 min in a water bath at 80 degrees C. The probability of growth was greater in bean or broccoli juice than in culture media following 10 min of heat treatment in these media. Growth was prevented by heat treatment of spores in vegetable juices or culture media at 80 degrees C for 100 min. We show for the first time that adding heat-treated vegetable juice to culture media can increase the number of heat-damaged spores of C. botulinum that can lead to colony formation.  (+info)

Inhibition of Rho at different stages of thymocyte development gives different perspectives on Rho function. (4/657)

Development of thymocytes can be staged according to the levels of expression of the cell-surface markers CD4, CD8, CD44, CD25 and CD2. Thymocyte development is regulated by a complex signalling network [1], one component of which is the GTPase Rho. The bacterial enzyme C3 transferase from Clostridium botulinum selectively ADP-ribosylates Rho in its effector-binding domain and thereby abolishes its biological function [2,3]. To explore the function of Rho in thymocyte development, we previously used the proximal promoter of the gene encoding the Src-family kinase p56lck to make transgenic mice that selectively express C3 transferase in the thymus [4,6]. In these mice, which lack Rho function from the earliest thymocyte stages, thymocyte numbers are reduced by approximately 50- to 100-fold. Here, we describe transgenic mice that express C3 transferase under the control of the locus control region (LCR) of the CD2 gene; this regulatory element drives expression at a later stage of thymocyte development than the lck proximal promoter [7]. In these mice, thymocyte numbers were also reduced by 50- to 100-fold, but unlike the lck-C3 mice, in which the reduction predominantly results from defects in cell survival of CD25(+) thymocyte progenitors, the CD2-C3 transgenic mice had a pre-T-cell differentiation block at the CD25(+) stage after rearrangement of the T-cell receptor (TCR) beta chains. Analysis of CD2-C3 mice demonstrated that Rho acts as an intracellular switch for TCR beta selection, the critical thymic-differentiation checkpoint. These results show that Rho-mediated survival signals for CD25(+) pre-T cells are generated by the extracellular signals that act on earlier thymocyte precursors and also that temporal cell-type-specific elimination of Rho can reveal different functions of this GTPase in vivo.  (+info)

In situ detection of the Clostridium botulinum type C1 toxin gene in wetland sediments with a nested PCR assay. (5/657)

A nested PCR was developed for detection of the Clostridium botulinum type C1 toxin gene in sediments collected from wetlands where avian botulism outbreaks had or had not occurred. The C1 toxin gene was detected in 16 of 18 sites, demonstrating both the ubiquitous distribution of C. botulinum type C in wetland sediments and the sensitivity of the detection assay.  (+info)

A predictive model that describes the effect of prolonged heating at 70 to 90 degrees C and subsequent incubation at refrigeration temperatures on growth from spores and toxigenesis by nonproteolytic Clostridium botulinum in the presence of lysozyme. (6/657)

Refrigerated processed foods of extended durability such as cook-chill and sous-vide foods rely on a minimal heat treatment at 70 to 95 degrees C and then storage at a refrigeration temperature for safety and preservation. These foods are not sterile and are intended to have an extended shelf life, often up to 42 days. The principal microbiological hazard in foods of this type is growth of and toxin production by nonproteolytic Clostridium botulinum. Lysozyme has been shown to increase the measured heat resistance of nonproteolytic C. botulinum spores. However, the heat treatment guidelines for prevention of risk of botulism in these products have not taken into consideration the effect of lysozyme, which can be present in many foods. In order to assess the botulism hazard, the effect of heat treatments at 70, 75, 80, 85, and 90 degrees C combined with refrigerated storage for up to 90 days on growth from 10(6) spores of nonproteolytic C. botulinum (types B, E, and F) in an anaerobic meat medium containing 2,400 U of lysozyme per ml (50 microg per ml) was studied. Provided that the storage temperature was no higher than 8 degrees C, the following heat treatments each prevented growth and toxin production during 90 days; 70 degrees C for >/=2,545 min, 75 degrees C for >/=463 min, 80 degrees C for >/=230 min, 85 degrees C for >/=84 min, and 90 degrees C for >/=33.5 min. A factorial experimental design allowed development of a predictive model that described the incubation time required before the first sample showed growth, as a function of heating temperature (70 to 90 degrees C), period of heat treatment (up to 2,545 min), and incubation temperature (5 to 25 degrees C). Predictions from the model provided a valid description of the data used to generate the model and agreed with observations made previously.  (+info)

Pure botulinum neurotoxin is absorbed from the stomach and small intestine and produces peripheral neuromuscular blockade. (7/657)

Clostridium botulinum serotype A produces a neurotoxin composed of a 100-kDa heavy chain and a 50-kDa light chain linked by a disulfide bond. This neurotoxin is part of a ca. 900-kDa complex, formed by noncovalent association with a single nontoxin, nonhemagglutinin subunit and a family of hemagglutinating proteins. Previous work has suggested, although never conclusively demonstrated, that neurotoxin alone cannot survive passage through the stomach and/or cannot be absorbed from the gut without the involvement of auxiliary proteins in the complex. Therefore, this study compared the relative absorption and toxicity of three preparations of neurotoxin in an in vivo mouse model. Equimolar amounts of serotype A complex with hemagglutinins, complex without hemagglutinins, and purified neurotoxin were surgically introduced into the stomach or into the small intestine. In some experiments, movement of neurotoxin from the site of administration was restricted by ligation of the pylorus. Comparison of relative toxicities demonstrated that at adequate doses, complex with hemagglutinins, complex without hemagglutinins, and pure neurotoxin can be absorbed from the stomach. The potency of neurotoxin in complex was greater than that of pure neurotoxin, but the magnitude of this difference diminished as the dosage of neurotoxin increased. Qualitatively similar results were obtained when complex with hemagglutinins, complex without hemagglutinins, and pure neurotoxin were placed directly into the intestine. This work establishes that pure botulinum neurotoxin serotype A is toxic when administered orally. This means that pure neurotoxin does not require hemagglutinins or other auxiliary proteins for absorption from the gastrointestinal system into the general circulation.  (+info)

Development of an in vitro bioassay for Clostridium botulinum type B neurotoxin in foods that is more sensitive than the mouse bioassay. (8/657)

A novel, in vitro bioassay for detection of the botulinum type B neurotoxin in a range of media was developed. The assay is amplified by the enzymic activity of the neurotoxin's light chain and includes the following three stages: first, a small, monoclonal antibody-based immunoaffinity column captures the toxin; second, a peptide substrate is cleaved by using the endopeptidase activity of the type B neurotoxin; and finally, a modified enzyme-linked immunoassay system detects the peptide cleavage products. The assay is highly specific for type B neurotoxin and is capable of detecting type B toxin at a concentration of 5 pg ml(-1) (0.5 mouse 50% lethal dose ml(-1)) in approximately 5 h. The format of the test was found to be suitable for detecting botulinum type B toxin in a range of foodstuffs with a sensitivity that exceeds the sensitivity of the mouse assay. Using highly specific monoclonal antibodies as the capture phase, we found that the endopeptidase assay was capable of differentiating between the type B neurotoxins produced by proteolytic and nonproteolytic strains of Clostridium botulinum type B.  (+info)

The purpose of this study was to compare and test the efficiency of the leading kinds of media being used for the isolation and identification of Clostridium botulinum type E strains, and to develop a more reliable method and media for the differentiation of this organism based on the "pearly layer" characteristic. The production of "pearly layer" around the colonies of the different types of C. botulinum on egg yolk enriched media has been used as an aid in differentiation and isolation of this group of bacteria. In this investigation a comparative study was conducted to test the efficiency of the "pearly layer" formation on liver veal agar egg yolk media (LVA) and trypticase agar egg yolk media (TA). Liver veal agar egg yolk media was not entirely satisfactory in that strains of C. botulinum type E and most non-toxic "type E-like" clostridia did not always give a typical reaction. These organisms in many cases produced a faint "pearly layer" or, in some cases, no "pearly layer" on the LVA egg ...
Grass sickness is an often fatal disease affecting horses especially in the springtime and leading to different signs of neurotoxicity. The pathogenesis still remains unclear, but there seems be a toxicoinfection with the neurotoxin-producing bacterium clostridium botulinum and the disease.
A newly published research study by scientists at the UK Institute of Food Research (IFR) has identified part of the mechanism by which the resistant endospores of the dangerous foodborne pathogen Clostridium botulinum (the cause of botulism) are able to germinate.. It is known that spore germination is initiated when certain small molecules (germinants) are recognised by a specific germinant receptors (GR) located in the inner membrane of the spore. The IFR researchers were able to identify two active GRs in the spores of Cl. botulinum, which respond to amino acid germinants and act in synergy, but are unable to function alone. Other GRs form a complex that seems to play a role in controlling the speed of germination.. The authors of the study say that understanding the germination mechanism of Cl. botulinum spores is essential if new control measures to prevent germination and subsequent toxin production by vegetative cells in food are to be developed. They suggest that it may be possible to ...

Formula Products Contaminated with Clostridium Botulinum - FAQ What is Clostridium botulinum? C. botulinum is an anaerobic, gram-positive, spore-forming rod that commonly found in the soil. Although the toxin is destroyed by boiling for 10 minutes or longer; inactivation of spores requires much higher temperature. What is the cause of botulism? Foodborne botulism results from ingestion of preformed toxin present in contaminated foods. Since C. botulinum can only grow in the absence of oxygen, foodborne botulism occurs in products with low oxygen content (e.g. in airtight packaging) as well as with right combination of storage and preservative parameters. The bacterium will grow and produce toxin in these products which are then eaten without sufficient heating or post-production cooking to inactivate the toxin. This is the case in lightly preserved foods such as fermented, salted, or smoked fish and meat products and in inadequately processed home-canned or home-bottled low acid foods. On the ...

The carboxy-terminal domain of the heavy chain recognizes a specific binding site, while the nitrogen-terminus transports the lighter chain into the nerve cytosol (Peck et al. 2010). The lighter chain contains metalloproteases that target specific proteins involved in controlling the exocytosis machinery (Verderio et al. 2006). The inhibition of this integral machinery stops the release of acetylcholine and the neuron fails to send an important signal throughout the body. The lighter chain also decreases the stability of the binding complex, further preventing acetylcholine from being able to bind to the synaptic vesicles (Peck et al. 2010). In addition to releasing neurotoxins when exposed to varying environmental conditions, Clostridium botulinum also increases production of proteases that are secreted from the cell to breakdown polypeptides to contribute to contaminating food and therefore increasing its own toxicity. A large proportion of the bacterias genome encodes for several different ...

The FDA Food Code Annex 3 explains the rationale for FDA Food Code Section 3-502.12 that "using ROP methods in food establishments has the advantage of providing extended shelf life to many foods because it inhibits spoilage organisms that are typically aerobic1." For this reason, ROP has become a very popular method of packaging in retail food establishments. Most raw animal foods require a HACCP Plan only, and not a variance, because high levels of competing microorganisms help to control hazards of concern, mainly Listeria monocytogenes. However, ROP of raw fish has additional requirements for storage because of the presence of non-proteolytic Clostridium botulinum type E in marine environments. This type of Clostridium botulinum can grow at temperatures as low as 37-38F2. Given the potency of the toxin that would be created, food products where C. botulinum type E is reasonably likely to occur must be stored at frozen temperatures.. The Fish and Fisheries Products Hazard Controls Guidance ...

There are three main types of botulism, categorized by the way the disease is acquired. Food-borne botulism is caused by eating food contaminated with botulinum toxin. This typically occurs when a stored food item contains Clostridium botulinum spores which begin to grow and produce the toxin within the food item, if environmental conditions are favorable.. Wound botulism occurs when the Clostridium botulinum bacteria infects a wound and then produces the toxin.. Infant botulism occurs when an infant consumes the spores of the botulinum bacteria which are commonly found in the environment. Once the bacteria enter an infants immature intestines, the spores can grow produce and release the toxins.. Adult intestinal botulism is the rarest form of botulism. Like infant botulism, it is caused when Clostridium botulinum spores are eaten in food. If environmental conditions are favorable in the intestinal tract, the bacteria may grow in that location and produce botulinum toxin, which is then absorbed ...

Botulism is a severe neurological disease caused by the complex family of botulinum neurotoxins (BoNT). Based on the different serotypes known today, a classification of serotype variants termed subtypes has been proposed according to sequence diversity and immunological properties. However, the relevance of BoNT subtypes is currently not well understood. Here we describe the isolation of a novel Clostridium botulinum strain from a food-borne botulism outbreak near Chemnitz, Germany. Comparison of its botulinum neurotoxin gene sequence with published sequences identified it to be a novel subtype within the BoNT/A serotype designated BoNT/A8. The neurotoxin gene is located within an ha-orfX+ cluster and showed highest homology to BoNT/A1, A2, A5, and A6. Unexpectedly, we found an arginine insertion located in the HC domain of the heavy chain, which is unique compared to all other BoNT/A subtypes known so far. Functional characterization revealed that the binding characteristics to its main ...
Although the worldwide incidence of infant botulism is rare, the majority of cases are diagnosed in the United States. An infant can acquire botulism by ingesting Clostridium botulinum spores, which are found in soil or honey products. The spores germinate into bacteria that colonize the bowel and synthesize toxin. As the toxin is absorbed, it irreversibly binds to acetylcholine receptors on motor nerve terminals at neuromuscular junctions. The infant with botulism becomes progressively weak, hypotonic and hyporeflexic, showing bulbar and spinal nerve abnormalities. Presenting symptoms include constipation, lethargy, a weak cry, poor feeding and dehydration. A high index of suspicion is important for the diagnosis and prompt treatment of infant botulism, because this disease can quickly progress to respiratory failure. Diagnosis is confirmed by isolating the organism or toxin in the stool and finding a classic electromyogram pattern. Treatment consists of nutritional and respiratory support until new

Two other forms of botulism also have occurred. Adult intestinal botulism is very rare and occurs among adults by the same route as infant botulism. Iatrogenic botulism is also very rare and can occur as a complication from injecting botulism toxin for cosmetic or medical purposes.. Who gets botulism?. Anyone can get botulism with about 200 cases reported in the United States each year. Most cases involve infant botulism which occurs in babies younger than 12 months old. Infant botulism has been associated with honey, a natural product that can contain botulism spores. Foodborne botulism can occur after eating home-canned, preserved or fermented foods that are contaminated with toxin. Foods with low acid content (e.g., asparagus, green beans, beets, corn, and potatoes) are the most common sources of home-canning related botulism. Wound botulism can occur more often in people who inject drugs or who have open wounds that are exposed to soil or gravel. Iatrogenic botulism is rare but can occur ...
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. ...
Three outbreaks of botulism type E occurring in waterbirds on Lake Michigan since autumn 1976 are discussed. Natural ingestion of food containing type E toxin by Ring-billed Gulls (Larus delawarensis) and the presence of type E toxin in the blood from moribund gulls were demonstrated. Concurrent presence of type C and type E botulinal toxins was found in a die-off of Common Loons (Gavia immer). In combination with previous reported outbreaks, these incidents suggest that this disease is geographically widespread in Lake Michigan, and that environmental conditions conducive to type E botulinal toxin production and consumption occur in both summer and autumn....
Abstract: The paper presents the more important data on the bacteria Clostridium botulinum, the appearance of botulism, hazard analysis and the possibilities for preventing botulism. Proteolytic strains of C.botulinum Group I, whose spores are resistant to heat, create toxins predominantly in cans containing slightly sour food items, in the event that the spores are not inactivated in the course of sterilization. Non-proteolytic strains of Group II are more sensitive to high temperatures, but they have the ability to grow and create toxins at low temperatures. Type E most often creates a toxin in vacuum-packed smoked fish, and the non-proteolytic strain type B in dried hams and certain pasteurized meat products. The following plays an important role in the prevention of botulism: reducing to a minimum meat contamination with spores of clostridia, implementing good hygiene measures and production practice during the slaughter of animals, the inactivation of spores of C. botulinum during ...

The citrate cycle (TCA cycle, Krebs cycle) is an important aerobic pathway for the final steps of the oxidation of carbohydrates and fatty acids. The cycle starts with acetyl-CoA, the activated form of acetate, derived from glycolysis and pyruvate oxidation for carbohydrates and from beta oxidation of fatty acids. The two-carbon acetyl group in acetyl-CoA is transferred to the four-carbon compound of oxaloacetate to form the six-carbon compound of citrate. In a series of reactions two carbons in citrate are oxidized to CO2 and the reaction pathway supplies NADH for use in the oxidative phosphorylation and other metabolic processes. The pathway also supplies important precursor metabolites including 2-oxoglutarate. At the end of the cycle the remaining four-carbon part is transformed back to oxaloacetate. According to the genome sequence data, many organisms seem to lack genes for the full cycle [MD:M00009], but contain genes for specific segments [MD:M00010 M00011 ...
Terpenoids, also known as isoprenoids, are a large class of natural products consisting of isoprene (C5) units. There are two biosynthetic pathways, the mevalonate pathway [MD:M00095] and the non-mevalonate pathway or the MEP/DOXP pathway [MD:M00096], for the terpenoid building blocks: isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). The action of prenyltransferases then generates higher-order building blocks: geranyl diphosphate (GPP), farsenyl diphosphate (FPP), and geranylgeranyl diphosphate (GGPP), which are the precursors of monoterpenoids (C10), sesquiterpenoids (C15), and diterpenoids (C20), respectively. Condensation of these building blocks gives rise to the precursors of sterols (C30) and carotenoids (C40). The MEP/DOXP pathway is absent in higher animals and fungi, but in green plants the MEP/DOXP and mevalonate pathways co-exist in separate cellular compartments. The MEP/DOXP pathway, operating in the plastids, is responsible for the formation of essential oil ...

I was always skeptical when it came to sushi because of hands constantly touching the rice, fish, and other ingredients that go in the roll. Rice is notorious for harbouring bacteria such as Bacillus cereus, a nasty little germ that is capable of forming a spore and can cause one to seriously embark on a journey of barfing. One of the critical control points in controlling the growth of this bacterium is to acidify the rice, that is, attain a pH of ,4.6. Synder1 reports that a pH of less than 4.6 will retard the growth of this bacterium and others such as Clostridium botulinum. I remember when I attempted to make sushi at home, I added enough vinegar to the rice that one bite would have given you an instant gastric ulcer, so I stopped. But are food operators testing their product to ensure the rice is at a pH of ,4.6?. The Arizona Daily Star reports that Sushi Ten was reported in having 11 critical health violations.. Sushi Ten, a midtown eatery specializing in raw seafood, failed its first ...

Clostridium botulinum is a taxonomic designation for at least four diverse species that are defined by the expression of one (monovalent) or two (bivalent) of seven different C. botulinum neurotoxins (BoNTs, A-G). The four species have been classified as C. botulinum Groups I-IV. The presence of bont genes in strains representing the different Groups is probably the result of horizontal transfer of the toxin operons between the species. Chromosome and plasmid sequences of several C. botulinum strains representing A, B, E and F serotypes and a C. butyricum type E strain were compared to examine their genomic organization, or synteny, and the location of the botulinum toxin complex genes. These comparisons identified synteny among proteolytic (Group I) strains or nonproteolytic (Group II) strains but not between the two Groups. The bont complex genes within the strains examined were not randomly located but found within three regions of the chromosome or in two specific sites within plasmids. A
National Wildlife Refuges and State Wildlife Sanctuaries in the subtropical Hawaiian Islands have experienced severe die-off events from avian botulism with increasing frequency. In the wetlands of Hanalei National Wildlife Refuge (Kauai, Hawaii) and elsewhere, avian botulism is fatal and is caused by food poisoning from the bacteria Clostridium botulinum (strain C). The impact of avian botulism may increase globally as the bacteria Clostridium botulinum (strain C) favors warmer water temperatures. Hawaiis non-migratory endemic waterbirds are especially vulnerable to avian botulism (type C) with epizootics causing mortality of thousands of endangered waterbirds in recent years. Migratory waterfowl and shorebirds are also affected. The endangered koloa maoli (Hawaiian duck; Anas wyvilliana) and critically-endangered Laysan duck (Laysan teal; A. laysanensis) have particularly high exposure because of their feeding behavior, limited wetland habitat, and small geographic ranges. Hawaiis endemic ...
0038]Botulinum toxin type A can be obtained by establishing and growing cultures of Clostridium botulinum in a fermenter and then harvesting and purifying the fermented mixture in accordance with known procedures. All the botulinum toxin serotypes are initially synthesized as inactive single chain proteins which must be cleaved or nicked by proteases to become neuroactive. The bacterial strains that make botulinum toxin serotypes A and G possess endogenous proteases and serotypes A and G can therefore be recovered from bacterial cultures in predominantly their active form. In contrast, botulinum toxin serotypes C1, D and E are synthesized by nonproteolytic strains and are therefore typically unactivated when recovered from culture. Serotypes B and F are produced by both proteolytic and nonproteolytic strains and therefore can be recovered in either the active or inactive form. However, even the proteolytic strains that produce, for example, the botulinum toxin type B serotype, only cleave a ...

Botulinum neurotoxins (BoNTs) produced by Clostridium botulinum are the most poisonous substances known to humankind. It is essential to have a simple, quick, and sensitive method for the detection and quantification of botulinum toxin in various media, including complex biological matrices. Our laboratory has developed a mass spectrometry-based Endopep-MS assay that is able to rapidly detect and differentiate all types of BoNTs by extracting the toxin with specific antibodies and detecting the unique cleavage products of peptide substrates. Botulinum neurotoxin type E (BoNT/E) is a member of a family of seven distinctive BoNT serotypes (A-G) and is the causative agent of botulism in both humans and animals. To improve the sensitivity of the Endopep-MS assay, we report here the development of novel peptide substrates for the detection of BoNT/E activity through systematic and comprehensive approaches. Our data demonstrate that several optimal peptides could accomplish 500-fold improvement in ...

Foodborne botulism, a potentially lethal neuroparalytic disease, is caused by ingesting preformed Clostridium botulinum neurotoxin. We reviewed surveillance data and reports from 1990 to 2000. Of 263 cases from 160 foodborne botulism events (episode of one or more related cases) in the United States, 103 (39%) cases and 58 events occurred in Alaska. Patients median age was 48 years; 154 (59%) were female; the case-fatality rate was 4%. The median number of cases per event was 1 (range 1-17). Toxin type A caused 51% of all cases; toxin type E caused 90% of Alaska cases. A particular food was implicated in 126 (79%) events. In the lower 49 states, a noncommercial food item was implicated in 70 (91%) events, most commonly, home-canned vegetables (44%). Two restaurant-associated outbreaks affected 25 persons. All Alaska cases were attributable to traditional Alaska Native foods. Botulism prevention efforts should be focused on those who preserve food at home, Alaska Natives, and restaurant workers.
Botulism is caused by a neurotoxin produced from the anaerobic, spore-forming bacterium Clostridium botulinum. Botulism in humans is usually caused by toxin types A, B, and E. Since 1973, a median of 24 cases of foodborne botulism, 3 cases of wound botulism, and 71 cases of infant botulism have been reported annually to the Centers for Disease Control and Prevention (CDC). New vehicles for transmission have emerged in recent decades, and wound botulism associated with black tar heroin has increased dramatically since 1994. Recently, the potential terrorist use of botulinum toxin has become an important concern.. Botulism is characterized by symmetric, descending, flaccid paralysis of motor and autonomic nerves, usually beginning with the cranial nerves.Blurred vision, dysphagia, and dysarthria are common initial complaints. The diagnosis of botulism is based on compatible clinical findings; history of exposure to suspect foods; and supportive ancillary testing to rule out other causes of ...

What is food-borne botulism? Food-borne botulism is a rare but serious type of food poisoning that can result in paralysis. It is caused by the Clostridium botulinum ( C. botulinum) bacterium. The bacteria produce a nerve toxin that can cause paralysis. Food-borne botulism can be fatal and is considered a medical emergency. What causes food-borne botulism? Food-borne botulism can be caused ...
Botulism is a serious illness that causes flaccid paralysis of muscles. It is caused by a neurotoxin, generically called botulinum toxin, that is produced by the bacterium Clostridium botulinum. There are seven distinct neurotoxins (types A-G) that Clostridium botulinum produce, but types A, B, and E (rarely F) are the most common that produce the flaccid paralysis in humans. The other types mainly cause disease in animals. Most Clostridium species produce only one type of neurotoxin.. ...
Food borne botulism is a severe intoxication caused by eating the preformed toxin present in contaminated food.. Food borne botulism occurs when the bacterium Clostridium botulinum is allowed to grow and produce toxin in food that is later eaten without sufficient heating or cooking to inactivate the toxin. Botulinum toxin is one of the most potent neurotoxins known.. Typically in a few hours to several days after you eat the contaminated food you will start to show the classic symptoms; blurred vision, dry mouth, and difficulty in swallowing. Gastrointestinal symptoms may or may not occur. If untreated, the paralysis always descends through the body starting at the shoulders and working its way down.. Celebrate Christmas and New Years Eve in Rome!. The most serious complication of botulism is respiratory failure where it is fatal in up to 10% of people. It may take months before recovery is complete.. If the disease is caught early enough it can be treated with antitoxin. If paralysis and ...
University of Georgia. For safetys sake, generations of babies have missed out on the sweet taste and healthy benefits of honey. But a new sterilization process may erase the risk and allow future toddlers to enjoy the sweet treat.. "Honey isnt recommended for babies because their immune systems are not developed," said Romeo Toledo, a food scientist with the University of Georgia College of Agricultural and Environmental Sciences.. Spores can survive. "The normal process for pasteurization of honey doesnt kill any (bacterial) spores present and could be a potential hazard for infant botulism," he said.. Eating honey poses no risk to adults with normal immune systems. But Clostridium botulinum spores found at very low levels in 5 percent to 10 percent of commercial honey samples can be deadly to infants.. For this reason, makers of childrens medicines like cough syrups normally use sugar and corn syrup instead of honey as sweeteners, Toledo said. Why is it so hard to kill the spores? "Spores ...
Journal of Pediatric Ophthalmology and Strabismus | Infant botulism is an exceedingly rare disease. Because confirmatory laboratory testing is not available for several days after time of presentation, infant botulism remains a clinical diagnosis. The authors demonstrate how raised intraocular pressure may provide an additional clinical clue to making the diagnosis.
Clostridium is a genus of Gram-positive bacteria, which includes several significant human pathogens, including the causative agent of botulism and an important cause of diarrhea, Clostridium difficile. They are obligate anaerobes capable of producing endospores. The normal, reproducing cells of Clostridium, called the vegetative form, are rod-shaped, which gives them their name, from the Greek κλωστήρ or spindle. Clostridium endospores have a distinct bowling pin or bottle shape, distinguishing them from other bacterial endospores, which are usually ovoid in shape. Clostridium species inhabit soils and the intestinal tract of animals, including humans. Clostridium is a normal inhabitant of the healthy lower reproductive tract of women. Clostridium contains around 100 species that include common free-living bacteria, as well as important pathogens. The main species responsible for disease in humans are: Clostridium botulinum can produce botulinum toxin in food or wounds and can cause ...
Read about outbreaks of botulism poisoning, causes (Clostridium botulinum toxin), symptoms (muscle paralysis, dry mouth, constipation), history, treatment, and types (foodborne, infant, wound). The botulinum toxin is one of the most lethal known substances.
A 6-month-old infant was admitted to the intensive care unit of our centre with a 2-day history of poor feeding, decreased movement of all limbs and respiratory distress. The patient was hypotonic and cold peripherally with a metabolic acidosis. Treatment for presumed sepsis was commenced. On day 4 of illness the child became unconscious and bradycardic, necessitating ventilation.. Cranial MRI was normal. Electromyography (EMG) was suggestive of Guillian-Barre syndrome but there was no improvement despite intravenous immunoglobulin therapy. Infantile botulism was queried, and a faecal sample sent for analysis to the regional Health Protection Laboratory confirmed the presence of toxin A producing Clostridium botulinum on PCR. Botulism immune globulin (BabyBIG) was given on day 16 of the illness. Improvement was notable but still slow, requiring continued ventilation for 6 weeks through a tracheostomy ...

Background: Two decades ago, botulinum neurotoxin (BoNT) type A was introduced to the commercial market. Subsequently, the toxin was approved by the FDA to address several neurological syndromes, involving muscle, nerve, and gland hyperactivity. These syndromes have typically been associated with abnormalities in cholinergic transmission. Despite the multiplicity of botulinal serotypes (designated as types A through G), therapeutic preparations are currently only available for BoNT types A and B. However, other BoNT serotypes are under study for possible clinical use and new clinical indications; Objective: To review the current research on botulinum neurotoxin serotypes A-G, and to analyze potential applications within basic science and clinical settings; Conclusions: The increasing understanding of botulinal neurotoxin pathophysiology, including the neurotoxins effects on specific neuronal populations, will help us in tailoring treatments for specific diagnoses, symptoms and patients.

First lets get an overview of what botulism is. Botulism is an illness that causes varying degrees of paralysis in the body from a toxin produced by the bacteria Clostridium botulinum. C. botulinum is practically everywhere - just about anything thats touched soil will contain spores. So why dont we get sick from it all the time? Most of the time this bacteria is dormant, and its only when conditions are right that it grows and makes this toxin. C. botulinum prefers an anaerobic (oxygen-free) environment thats not too acidic, not too salty, not too crowded with other bacteria, and it does especially well at warm temperatures. A unique characteristic of C. botulinum is its ability to survive high temperatures for relatively long periods of time ...
Botulism is a neuromuscular (paralytic) disease cause by a bacterial toxin acting in the intestine (enterotoxin) and causing neuromuscular poisoning (resulting from clostridium botulinum toxin).
The Botulinum neurotoxin serotype A (BoNT/A), a byproduct of the Clostridium botulinum bacteria, is responsible for causing the paralytic disease, Botulism. BoNT/A has a lethal dose (LD50) of 1.3 ng/kg of body weight in humans, making it the worlds most lethal toxin. Its potency, ease of extraction, and reproducibility raises concern the toxin may be weaponized and used in bioterrorism. The therapeutics currently available to treat the disease are not viable for large scale infections, resulting in mass casualties in the case of an attack. Therefore, efforts to develop alternative therapeutics are essential. The toxin is a dimer composed of a heavy chain (HC) and a light chain (LC). The HC binds to neuronal cells and aids the LC into the cytosol of the cell. Once in the cytosol the LC, a zinc metalloprotease, terminates neurotransmission by cleaving SNARE proteins. Our laboratory focuses on the development and synthesis of small molecules as a therapeutic countermeasure against BoNT/A LC. Previously,
Botulism is a rare but very serious type of food poisoning caused by toxins produced by bacteria ( Clostridium botulinum ) that are commonly found in soil. Botulism is often caused by food that is not home-canned properly, such as home-canned beans and corn. In children younger than 1 year, botulism may be caused by...
Botulism Definition Botulism is an acute, progressive condition caused by botulinum toxin, a natural poison produced by the spore-forming bacteria Clostridium botulinum.
Mass spectrometry has recently become a powerful technique for bacterial identification. Mass spectrometry approaches generally rely upon introduction of the bacteria into a matrix-assisted laser-desorption time-of-flight (MALDI-TOF) mass spectrometer with mass spectrometric recognition of proteins specific to that organism that form a reliable fingerprint. With some bacteria, such as Bacillus anthracis and Clostridium botulinum, the health threat posed by these organisms is not the organism itself, but rather the protein toxins produced by the organisms. One such example is botulinum neurotoxin (BoNT), a potent neurotoxin produced by C. botulinum. There are seven known serotypes of BoNT, A-G, and many of the serotypes can be further differentiated into toxin variants, which are up to 99.9% identical in some cases. Mass spectrometric proteomic techniques have been established to differentiate the serotype or toxin variant of BoNT produced by varied strains of C. botulinum. Detection of potent ...
0003]These patents concentrate on how to define the honey, such as the amount of hydrogen peroxide it produces and other parameters. Also in NL 1016398, it is specifically stated that honey must be irradiated for the treatment of wounds. Honey contains a number of bacteria, yeasts and fungi. Some of those bacteria are anaerobic such as Clostridium Botulinum strains. These can usually be found in raw honey and can, when used on wounds, develop and cause gas gangrene. For instance in 270 samples of unprocessed honey from seven different countries, 8.5% carried up to 40-80 spores per gram of honey (Postmes T., van den Bogaard A. E., Hazen M., The sterilization of honey with cobalt 60 gamma radiation: a study of honey spiked with spores of Clostridium Botilinum and Bacillus Subtilis, Experientia 51 (1995), p. 986-989). Therefore, honey that is used to make a wound care ointment or gel is irradiated with an average dose of 15 -30 kGry. The irradiation of honey with such high doses is only done for ...

Botulinum Toxin Therapy for Chronic Migraine What is botulinum toxin? Botulinum toxin (Onabotulinum Toxin A) is made from a toxin produced by the bacterium Clostridium botulinum. In high doses it can produce muscle paralysis. In low doses, it is used to treat many conditions. Botulinum toxin is a medicine approved by the FDA to prevent chronic migraines. How does it work? It is unclear how botulinum toxin treats chronic migraine. Botulinum toxin injections can cause relaxation of muscles and can block nerve signal transmission. The effects last about 12 weeks. It works best if treatment is done every 12 weeks. It may take more than one treatment to feel the full effect of botulinum toxin therapy. How do I know it will help me? Botulinum toxin treatments are expensive and come with some risk. Both your provider and insurance consider this treatment when less invasive treatments have not worked for you. Botulinum toxin has been found to work well for chronic migraine. Most people (up to 70%) feel ...

The bottom line?. The authors concluded: "This study suggests a potentially meaningful role for zinc and/or phytase supplementation in increasing the degree and duration of botulinum toxin effect in the treatment of cosmetic facial rhytids, benign essential blepharospasm, and hemifacial spasm.". When a skeletal muscle nerve ending is stimulated it releases acetylcholine, which triggers an impulse to the muscle. Botulinum toxin blocks release of acetylcholine at the neuromuscular junction. As shown in the photo above, zinc is part of the botulinum toxin structure. A more detailed explanation is here.. Phytases are enzymes that increase zinc absorption from the intestines, making more available in the circulation and at the botulinum toxin site of action.. This study is important because it shows that taking more zinc may increase the response and duration of effect of "Botox" type drugs. This may be particularly useful for patients who experience a decline in response over time.. 4/10/13 9:28 ...
The botulinum toxin as a therapeutic agent: molecular and pharmacological insights Roshan Kukreja,1 Bal Ram Singh2 1Department of Chemistry and Biochemistry, University of Massachusetts, 2Botulinum Research Center, Institute of Advanced Sciences, Dartmouth, MA, USA Abstract: Botulinum neurotoxins (BoNTs), the most potent toxins known to mankind, are metalloproteases that act on nerve–muscle junctions to block exocytosis through a very specific and exclusive endopeptidase activity against soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins of presynaptic vesicle fusion machinery. This very ability of the toxins to produce flaccid muscle paralysis through chemical denervation has been put to good use, and these potentially lethal toxins have been licensed to treat an ever expanding list of medical disorders and more popularly in the field of esthetic medicine. In most cases, therapeutic BoNT preparations are high-molecular-weight protein complexes consisting of
