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.
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.
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.
A disease caused by potent protein NEUROTOXINS produced by CLOSTRIDIUM BOTULINUM which interfere with the presynaptic release of ACETYLCHOLINE at the NEUROMUSCULAR JUNCTION.

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)

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)

Clostridium botulinum strains that produce botulinum neurotoxin type E (BoNT/E) are most commonly isolated from botulism cases, marine environments, and animals in regions of high latitude in the Northern hemisphere. A strain of C. botulinum type E (CDC66177) was isolated from soil in Chubut, Argentina. Previous studies showed that the amino acid sequences of BoNT/E produced by various strains differ by | 6% and that the type E neurotoxin gene cluster inserts into the rarA operon. Genetic and mass spectral analysis demonstrated that the BoNT/E produced by CDC66177 is a novel toxin subtype (E9). Toxin gene sequencing indicated that BoNT/E9 differed by nearly 11% at the amino acid level compared to BoNT/E1. Mass spectrometric analysis of BoNT/E9 revealed that its endopeptidase substrate cleavage site was identical to other BoNT/E subtypes. Further analysis of this strain demonstrated that its 16S rRNA sequence clustered with other Group II C. botulinum (producing BoNT types B, E, and F) strains. Genomic

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 ...

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 ...

A previous version of draft guidelines for cannabis testing in Florida listed Clostridium botulinum as a target for microbial testing. On the surface, this seems like a prudent action. After all, C. botulinum is a nasty organism that is responsible for a life-threatening disease called botulism. However, because it is so dangerous, the CDC/USDA has placed it on the FEDERAL SELECT AGENTS AND TOXINS LIST. This makes it very difficult for labs to acquire C. botulinum organisms to validate their tests. It requires BL3 storage and BL2 CO2 glove boxes to culture because its an obligate anaerobe. We dont know of a single cannabis testing lab that has a BL3 lab. There are also no attenuated strains available.. We know how hard it can be to test for C. botulinum. In a 2016 study, we detected C. botulinum DNA on a cannabis sample using 16S sequencing of short amplicons. Those results should always be verified with a species-specific confirmation assay, which we have designed. Our qPCR assay detects the ...
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 ...

The hemagglutinating protein HA33 from Clostridium botulinum is associated with the large botulinum neurotoxin secreted complexes and is critical in toxin protection, internalization, and possibly activation. We report the crystal structure of serotype A HA33 (HA33/A) at 1.5 A resolution that contains a unique domain organization and a carbohydrate recognition site. In addition, sequence alignments of the other toxin complex components, including the neurotoxin BoNT/A, hemagglutinating protein HA17/A, and non-toxic non-hemagglutinating protein NTNHA/A, suggests that most of the toxin complex consists of a reoccurring beta-trefoil fold ...
A description is given of a food intoxication in 1895 at Ellezelles, a village in Belgium. As a result 3 persons died within a few days and others became seriously ill.

Clostridium botulinum is bacteria which is present in untreated water, soil and dust all over the world and can also be found on a number of food items, for example, anything which has been grown in soil may have had contact with the bacteria. The bacteria in its natural state is not harmful but, as an obligate anaerobe, if it is deprived of oxygen, its spores start to produce toxins which can, in very rare cases, be fatal. It is no exaggeration to say that it is probably the most dangerous of food borne illnesses that can be contracted. The toxins attack the nervous system, disabling the neurotransmitters which carry instructions from the brain to our muscles, thus causing paralysis. Symptoms include nausea, dizziness, vomiting, double vision, drooping eyelids and paralysis amongst others. It can be treated with antitoxins which prevent the toxins from travelling round the body so an immediate visit to the doctor or hospital is absolutely imperative.. Foodborne botulism is generally ...

Background: The C3bot1 protein (~23 kDa) from Clostridium botulinum ADP-ribosylates and thereby inactivates Rho. C3bot1 is selectively taken up into the cytosol of monocytes/macrophages but not of other cell types such as epithelial cells or fibroblasts. Most likely, the internalization occurs by a specific endocytotic pathway via acidified endosomes. Methodology/Principal Findings: Here, we tested whether enzymatic inactive C3bot1E174Q serves as a macrophage-selective transport system for delivery of enzymatic active proteins into the cytosol of such cells. Having confirmed that C3bot1E174Q does not induce macrophage activation, we used the actin ADP-ribosylating C2I (~50 kDa) from Clostridium botulinum as a reporter enzyme for C3bot1E174Q-mediated delivery into macrophages. The recombinant C3bot1E174Q-C2I fusion toxin was cloned and expressed as GST-protein in Escherichia coli. Purified C3bot1E174Q-C2I was recognized by antibodies against C2I and C3bot and showed C2I-specific enzyme activity ...

Botulism is caused by intoxication with the any of the seven distinct neurotoxins produced by the bacillus, |I|Clostridium botulinum.|/I| The toxins are proteins with molecular weights of approximately 150,000, which bind to the presynaptic membrane of neurons at peripheral cholinergic synapses to prevent release of acetylcholine and block neurotransmission.
General Information: Clostridium botulinum A strain Hall was received at Fort Detrick from Harvard University in 1947. The strain is presumably one from Dr. Ivan Halls collection, but the exact strain number has been lost. This strain produces high amounts of type A toxin. Produces botulinum, one of the most potent toxins known. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive ...

Tumor endothelial marker (TEM) 5 is an adhesion G-protein-coupled receptor upregulated in endothelial cells during tumor and physiologic angiogenesis. So far, the mechanisms leading to upregulation of TEM5 and its function during angiogenesis have not been identified. Here, we report that TEM5 expression in endothelial cells is induced during capillary-like network formation on Matrigel, during capillary morphogenesis in a three-dimensional collagen I matrix, and upon confluence on a two-dimensional matrix. TEM5 expression was not induced by a variety of soluble angiogenic factors, including VEGF and bFGF, in subconfluent endothelial cells. TEM5 upregulation was blocked by toxin B from Clostridium difficile, an inhibitor of the small GTPases Rho, Rac, and Cdc42. The Rho inhibitor C3 transferase from Clostridium botulinum did not affect TEM5 expression, whereas the Rac inhibitor NSC23766 suppressed TEM5 upregulation. An excess of the soluble TEM5 extracellular domain or an inhibitory monoclonal ...
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 ...
TY - JOUR. T1 - Structural and biochemical characterization of botulinum neurotoxin subtype b2 binding to its receptors. AU - Davies, Jonathan R.. AU - Masuyer, Geoffrey. AU - Stenmark, Pål. PY - 2020/9/17. Y1 - 2020/9/17. N2 - Botulinum neurotoxins (BoNTs) can be used therapeutically to treat a wide range of neuromuscular and neurological conditions. A collection of natural BoNT variants exists which can be classified into serologically distinct serotypes (BoNT/B), and further divided into subtypes (BoNT/B1, B2,...). BoNT subtypes share a high degree of sequence identity within the same serotype yet can display large variation in toxicity. One such example is BoNT/B2, which was isolated from Clostridium botulinum strain 111 in a clinical case of botulism, and presents a 10-fold lower toxicity than BoNT/B1. In an effort to understand the molecular mechanisms behind this difference in potency, we here present the crystal structures of BoNT/B2 in complex with the ganglioside receptor GD1a, and ...
The objective of the project is the development of in vitro detection methods for the different toxins (A, B, C, D, E and F) of Clostridium botulinum by optimizing both a competitive immuno-PCR test (icqPCR) and a quantitative immuno-PCR (iqPCR) and by comparing one to another with regard to the obtained specificity and sensitivity of detection for each type of botulinum toxin as well as to compare them to the reference method for detection of botulinum toxins being the mice toxicity test ...

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 ...

In a news release, the Canadian Food Inspection Agency (CFIA) said three people are ill after eating fesikh from Lotus Catering and Fine Food in Toronto. The CFIA said the fish has been recalled because it may be contaminated with Clostridium botulinum, the bacterium that produces toxins which can cause botulism.. Fesikh is a traditional Egyptian fish dish made from mullet, which is dried in the sun until it putrefies and then salted and left to pickle for at least 40 days. Despite annual warnings by health officials against the dangers of fesikh, most Egyptians eat it during the Sham al-Nessim spring celebration.. Cases of food poisoning from incorrectly prepared fesikh are reported each year.. Food contaminated with Clostridium botulinum toxin may not look or smell spoiled. Consumption of food contaminated with the toxin may cause nausea, vomiting, fatigue, dizziness, headache, double vision, dry throat, respiratory failure and paralysis. In severe cases of illness, people may die.. For more ...
In previous eras, conditions conducive to the survival of C. botulinum spores and their subsequent germination in food were much more common. Nevertheless, enduring methods of preparing certain homemade foods, new ways of packaging commercial foods, new food preferences, or new techniques for preparing familiar foods that support the growth of C. botulinum render it likely that foodborne botulism will afflict humans for the foreseeable future.. From 1990 to 2000, home-canned foods remained a leading cause of foodborne botulism in the United States. New interventions should be explored to ensure that methods of home canning vegetables incorporate adequate barriers to prevent C. botulinum germination. Possible areas of research may include development of practical dye indicators for pH and temperatures above those of refrigeration. Botulism associated with Alaska Native foods is likely an age-old problem, compounded in recent decades by altering traditional practices in an unsafe manner, in ...

D & M Smoked Fish, Inc. located in Queens, New York, is recalling Haifa brand vacuum packaged Schmaltz Herring with the lot number 168, because the product was found to be uneviscerated.. The lot being recalled is a product of Norway, individually vacuum-packed in clear plastic pouches with lot # 168 & Sell by date of 7/20/10 indicated on the label and distributed through food retailers in the NY area.. The Schmaltz Herring was sampled by a New York State Agriculture and Markets Food Inspector during a routine inspection. Analysis of the product by New York State Food Laboratory personnel confirmed that Schmaltz Herring was improperly eviscerated prior to processing.. The sale of uneviscerated fish is prohibited under New York State Agriculture and Markets regulations because of Clostridium Botulinum spores are more likely to be concentrated in the viscera than any other portion of the fish. Uneviscerated fish has been linked to outbreaks of botulism poisoning.. Botulism is a serious and ...
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 ...

General Information: Clostridium botulinum B str. Eklund 17B is a nonproteolytic botulism neurotoxin B strain. This strain was isolated from marine sediments taken off the coast of Washington, USA and was not associated with botulism. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive clostridia-like ancestors with a low GC content in DNA.

1]Chinese regulators have asked an American firm to pull two products from the market[2].. On Tuesday, the General Administration of Quality Supervision, Inspection and Quarantine requested that Abbott Laboratories (ABT[3]) recall two batches infant formula after New Zealands embassy warned that some of the formula could contain a harmful bacteria, the Wall Street Journal notes.. The regulator said that formula, which use ingredients from New Zealands Fonterra Co-Operative Group, a diary farm, may have been contaminated by Clostridium botulinum, which causes botulism, a potentially debilitating and fatal disease.. Chinese regulators are also recalling a number of other food and beverage products containing potentially contaminated Fonterra ingredients across China..

Hepatitis A and other viral diseases may be passed through the hands of infected people onto the hands of food handlers or into sewage. Shellfish and other foods which may have been exposed to sewage-contaminated water can transmit these viral diseases.. Botulism is a rare but deadly form of food poisoning caused by Clostridium botulinum, which is found almost everywhere, including in soil and water. Low acid foods, such as meat, fish, poultry, or vegetables, that are improperly canned or improperly preserved may be breeding grounds for this bacteria. Raw honey and corn syrup can also cause botulism in infants. Babies under the age of 1 year old should never be given honey or corn syrup for this reason.. ...
Botulinum toxin is a protein derived from a bacterium called Clostridium botulinum, having undergone a proven safe and highly effective purification process. It is therefore organic and completely safe. Since the early 1970s it has been used in treating conditions in many fields of medicine including neurology and ophthalmology and it has been used in aesthetic medicine for over 20 years.. In over 30 years of use in medicine, there have never been any reported serious allergic reactions and with such longevity we can say with certainty that there are no long term side effects. The most important thing to remember is that this treatment is non-permanent and very safe. The is metabolised at the injection site and it does not spread to any other parts of the body.. ...

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 ...
