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.
Subtype of CLOSTRIDIUM BOTULINUM that produces botulinum toxin type E which is neurotoxic to humans and animals.
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)

Differentiation of the gene clusters encoding botulinum neurotoxin type A complexes in Clostridium botulinum type A, Ab, and A(B) strains. (1/23)

We describe a strategy to identify the clusters of genes encoding components of the botulinum toxin type A (boNT/A) complexes in 57 strains of Clostridium botulinum types A, Ab, and A(B) isolated in Italy and in the United States from different sources. Specifically, we combined the results of PCR for detecting the ha33 and/or p47 genes with those of boNT/A PCR-restriction fragment length polymorphism analysis. Three different type A toxin gene clusters were revealed; type A1 was predominant among the strains from the United States, whereas type A2 predominated among the Italian strains, suggesting a geographic distinction between strains. By contrast, no relationship between the toxin gene clusters and the clinical or food source of strains was evident. In two C. botulinum type A isolates from the United States, we recognized a third type A toxin gene cluster (designated type A3) which was similar to that previously described only for C. botulinum type A(B) and Ab strains. Total genomic DNA from the strains was subjected to pulsed-filed gel electrophoresis and randomly amplified polymorphic DNA analyses, and the results were consistent with the boNT/A gene clusters obtained.  (+info)

A novel neurotoxoid vaccine prevents mucosal botulism. (2/23)

The threat posed by botulism, classically a food- and waterborne disease with a high morbidity and mortality, has increased exponentially in an age of bioterrorism. Because botulinum neurotoxin (BoNT) could be easily disseminated by terrorists using an aerosol or could be used to contaminate the food or water supply, the Centers for Disease Control and Prevention and the National Institute of Allergy and Infectious Diseases has classified it as a category A agent. Although clearly the development of a safe and effective mucosal vaccine against this toxin should be a high priority, essentially no studies to date have assessed mucosal immune responses to this disease. To bridge this gap in our knowledge, we immunized mice weekly for 4 wk with nasal doses of BoNT type A toxoid and a mutant of cholera toxin termed E112K. We found elevated levels of BoNT-specific IgG Abs in plasma and of secretory IgA Abs in external secretions (nasal washes, saliva, and fecal extracts). When mice given nasal BoNT vaccine were challenged with 4 x 10(3) LD50 of BoNT type A (BoNT/A) via the i.p. route, complete protection was seen, while naive mice given the same dosage died within 2 h. To further confirm the efficacy of this nasal BoNT vaccine, an oral LD50 was determined. When mice were given an oral challenge of 5 microg (2 x oral LD50) of progenitor BoNT/A, all immunized mice survived beyond 5 days, while nonimmunized mice did not. The fecal extract samples from nasally vaccinated mice were found to contain neutralizing secretory IgA Abs. Taken together, these results show that nasal BoNT/A vaccine effectively prevents mucosal BoNT intoxication.  (+info)

Efficient DNA fingerprinting of Clostridium botulinum types A, B, E, and F by amplified fragment length polymorphism analysis. (3/23)

Amplified fragment length polymorphism (AFLP) analysis was applied to characterize 33 group I and 37 group II Clostridium botulinum strains. Four restriction enzyme and 30 primer combinations were screened to tailor the AFLP technique for optimal characterization of C. botulinum. The enzyme combination HindIII and HpyCH4IV, with primers having one selective nucleotide apiece (Hind-C and Hpy-A), was selected. AFLP clearly differentiated between C. botulinum groups I and II; group-specific clusters showed <10% similarity between proteolytic and nonproteolytic C. botulinum strains. In addition, group-specific fragments were detected in both groups. All strains studied were typeable by AFLP, and a total of 42 AFLP types were identified. Extensive diversity was observed among strains of C. botulinum type E, whereas group I had lower genetic biodiversity. These results indicate that AFLP is a fast, highly discriminating, and reproducible DNA fingerprinting method with excellent typeability, which, in addition to its suitability for typing at strain level, can be used for C. botulinum group identification.  (+info)

Genotyping Clostridium botulinum toxinotype A isolates from patients using amplified rDNA restriction analysis. (4/23)

In this study, the application of amplified rDNA restriction analysis (ARDRA) for characterizing Clostridium botulinum toxinotype A strains isolated from individuals with botulism was evaluated. Ten restriction enzymes were tested for their suitability in ARDRA as a typing method and HhaI was selected for the best outcome. Analysis of HhaI restriction profiles of the amplified products divided C. botulinum isolates into three clusters. Non-toxigenic Clostridium sporogenes strains showed an ARDRA restriction pattern that was distinct from those observed for C. botulinum. The successful use of ARDRA for subdivision of C. botulinum in this study confirmed that this technique is a powerful method for typing of C. botulinum toxinotype A clonal diversity. In addition, it is rapid, sensitive and simple.  (+info)

Expression of botulinum neurotoxins A and E, and associated non-toxin genes, during the transition phase and stability at high temperature: analysis by quantitative reverse transcription-PCR. (5/23)

Production of botulinum neurotoxin A (BoNT/A) and associated non-toxic proteins (ANTPs), which include a non-toxic non-haemagglutinin (NTNH/A) as well as haemagglutinins (HAs), was found previously to be dependent upon an RNA polymerase alternative sigma factor (BotR/A). Expression of the botR/A, bont/A and antp genes, monitored by reverse transcription and real-time PCR analysis, occurred concomitantly at the transition between the exponential and stationary growth phases of Clostridium botulinum A. The botR/A expression level was about 100-fold less than those of the bont/A and antp genes. Therefore, BotR/A is an alternative sigma factor controlling the botulinum A locus genes during the transition phase. The highest toxin concentration was released into the culture supernatant 12 h after maximum expression of the botR/A, bont/A and antp genes, without any apparent bacterial lysis. Toxin levels were then stable over 5 days in cultures at 37 degrees C, whereas a dramatic decrease in lethal activity was observed between 24 and 48 h in cultures at 44 degrees C. High temperature did inhibit transcription, since expression levels of the botR/A, bont/A and antp genes were similar in cultures at 37 and 44 degrees C. However, incubation at 44 degrees C triggered a calcium-dependent protease that degraded BoNT/A and NTNH/A, but not HAs. In C. botulinum E, which contains no gene related to botR, the bont/E and p47 genes were also expressed during the transition phase, and no protease activation at 44 degrees C was evident.  (+info)

Determination of neurotoxin gene expression in Clostridium botulinum type A by quantitative RT-PCR. (6/23)

Real time reverse transcription (RT)-PCR was used to quantify the expression of the botulinum neurotoxin type A (BoNT/A) gene (cntA) by normalization with the expression of 16S rRNA. The method were confirmed by monitoring the mRNA levels of cntA during growth in five type A strains. In all but one of the strains the expression of cntA mRNA was maximal in the late exponential phase, and approximately 35-fold greater than in the early exponential phase. The concentration of the extracellular BoNT/A complex detected by ELISA was highest in stationary phase. Sodium nitrite and sorbic acid completely inhibited growth at 20 ppm and 4 mg ml-1, respectively. CntA expression became lower in proportion to the concentration of sorbic acid, and this reduction was confirmed by mouse bioassay. Our results show that real time RT-PCR can be used to quantify levels of C. botulinum type A neurotoxin transcripts and to assess the effects of food additives on botulinal risk.  (+info)

SYBR green real-time PCR method to detect Clostridium botulinum type A. (7/23)

Botulinum toxins (BoNTs) are classically produced by Clostridium botulinum but rarely also from neurotoxigenic strains of Clostridium baratii and Clostridium butyricum. BoNT type A (BoNT/A), BoNT/B, BoNT/E, and very rarely BoNT/F are mainly responsible for human botulism. Standard microbiological methods take into consideration only the detection of C. botulinum. The presumptive identification of the toxigenic strains together with the typing of BoNT has to be performed by mouse bioassay. The development of PCR-based methods for the detection and typing of BoNT-producing clostridia would be an ideal alternative to the mouse bioassay. The objective of this study was to develop a rapid and robust real-time PCR method for detecting C. botulinum type A. Four different techniques for the extraction and purification of DNA from cultured samples were initially compared. Of the techniques used, Chelex 100, DNeasy tissue kit, InstaGene matrix DNA, and boiling, the boiling technique was significantly less efficient than the other three. These did not give statistically different results, and Chelex 100 was chosen because it was less expensive than the others. In order to eliminate any false-negative results, an internal amplification control was synthesized and included in the amplification mixture according to ISO 22174. The specificity of the method was tested against 75 strains of C. botulinum type A, 4 strains of C. botulinum type Ab, and 101 nontarget strains. The detection limit of the reaction was less than 6 x 10(1) copies of C. botulinum type A DNA. The robustness of the method was confirmed using naturally contaminated stool specimens to evaluate the tolerance of inhibitor substances. SYBR green real-time PCR showed very high specificity for the detection of C. botulinum types A and Ab (inclusivity and exclusivity, 100%).  (+info)

Structures of Clostridium botulinum Neurotoxin Serotype A Light Chain complexed with small-molecule inhibitors highlight active-site flexibility. (8/23)

The potential for the use of Clostridial neurotoxins as bioweapons makes the development of small-molecule inhibitors of these deadly toxins a top priority. Recently, screening of a random hydroxamate library identified a small-molecule inhibitor of C. botulinum Neurotoxin Serotype A Light Chain (BoNT/A-LC), 4-chlorocinnamic hydroxamate, a derivative of which has been shown to have in vivo efficacy in mice and no toxicity. We describe the X-ray crystal structures of BoNT/A-LC in complexes with two potent small-molecule inhibitors. The structures of the enzyme with 4-chlorocinnamic hydroxamate or 2,4-dichlorocinnamic hydroxamate bound are compared to the structure of the enzyme complexed with L-arginine hydroxamate, an inhibitor with modest affinity. Taken together, this suite of structures provides surprising insights into the BoNT/A-LC active site, including unexpected conformational flexibility at the S1' site that changes the electrostatic environment of the binding pocket. Information gained from these structures will inform the design and optimization of more effective small-molecule inhibitors of BoNT/A-LC.  (+info)

Despite being separated by over 7,000 miles, two species of crows that are distinct in appearance and size shed only the species C. jejuni. This was confirmed by using two well-established PCR protocols that targeted different genes. C. jejuni was isolated almost at the same frequency from Kolkata samples (69%) as from samples from the greater Seattle area (61%). Other studies have reported the presence of campylobacters in 21 to 68% of fecal samples from crows (10, 12), and our results are in agreement with those, although Weis et al. also found Campylobacter coli and C. lari isolates, based on 16S rRNA gene sequence analysis (10).. The most unexpected result was that of the CDT gene cluster. In all of the 74 isolates in which the cluster was detected, irrespective of whether their origin was in the United States or Eastern India, PCR amplicons of the same size were obtained, at approximately 1,350 bp instead of the full-length 2,100 bp found in the wild type. The sequencing of 22 ...
The Staphylococcus aureus genome encodes three ferric uptake repressor (Fur) homologues: Fur, PerR, and Zur. To determine the exact role of Fur in S. aureus, we inactivated thefur gene by allelic replacement using a tetracycline resistance cassette, creating strain MJH010 (fur). The mutant had a growth defect in rich medium, and this defect was exacerbated in metal-depleted CL medium. This growth defect was partially suppressed by manganous ion, a metal ion with known antioxidant properties. This suggests that the fur mutation leads to an oxidative stress condition. Indeed, MJH010 (fur) has reduced levels of catalase activity resulting from decreased katA transcription. Using akatA-lacZ fusion we have determined that Fur functions, either directly or indirectly, as an iron-dependent positive regulator of katA expression. Transcription of katA is coregulated by Fur and PerR, since in MJH010 (fur) transcription was still repressed by manganese while transcription in MJH201 (fur perR) was ...

Growth in real (inflation-adjusted) GDP in calendar year 2013 will be just 0.5 percent, CBO expects-with the economy projected to contract at an annual rate of 1.3 percent in the first half of the year and expand at an annual rate of 2.3 percent in the second half. Given the pattern of past recessions as identified by the National Bureau of Economic Research, such a contraction in output in the first half of 2013 would probably be judged to be a recession. ...
Background: Contemporary technologies and assay methods are being explored continuously for rapid and sensitive detection of biologically active BoNTs in food and environmental samples to facilitate enhanced public health response. Previously, FRET based substrates were used to detect the presence of active BoNTs in samples. However their efficacy to screen food samples and identify serotypes associated with unknown samples is largely limited. In this work, we have evaluated the application of cleavage sensitive monoclonal antibodies (CSM) to detect enzymatically active BoNT Type A using Bio-Layer Interferometry (BLI). CSM are developed to recognize only the neo-epitopes that are generated after the cleavage of target substrates by BoNTs. Methods: BLI platform (Pall Fortebio Octet) was used to evaluate the ability of type-A CSM (CSM-A) to specifically detect the catalytic action of BoNT/A, by measuring its binding to the BoNT/A cleaved fragment of SNAP-25. BLI is a powerful, versatile, rapid and ...

Background The dinoflagellate Alexandrium minutum typically produces paralytic shellfish poisoning (PSP) toxins, which are known only from cyanobacteria and dinoflagellates. While a PSP toxin gene cluster has recently been characterized in cyanobacteria, the genetic background of PSP toxin production in dinoflagellates remains elusive. Results We constructed and analysed an expressed sequence tag (EST) library of A. minutum, which contained 15,703 read sequences yielding a total of 4,320 unique expressed clusters. Of these clusters, 72% combined the forward-and reverse reads of at least one bacterial clone. This sequence resource was then used to construct an oligonucleotide microarray. We analysed the expression of all clusters in three different strains. While the cyanobacterial PSP toxin genes were not found among the A. minutum sequences, 192 genes were differentially expressed between toxic and non-toxic strains. Conclusions Based on this study and on the lack of identified PSP synthesis ...
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 federal government will spend 11% less on the Affordable Care Act over the next decade than previously anticipated, according to updated figures released Monday by the Congressional Budget Office, the Washington Posts Wonkblog reports.. Overall, the ACA is expected to cost $1.2 trillion over the next 10 years. By comparison, CBO in March 2010 estimated the ACA would cost $710 billion from 2015 to 2019. However, CBO now estimates that the law will cost about $506 billion, or about 29% less, during that time period (Ehrenfreund, Wonkblog, Washington Post, 3/9).. According to CBO, the decline in the estimated cost is the result of fewer people enrolling in exchange coverage than the office had anticipated, as well as a slowdown in health care spending growth (Ferris, The Hill, 3/9). In addition, fewer individuals signed up for Medicaid coverage and more individuals were enrolled in employer-sponsored health plans and private coverage than had been expected (Wonkblog, Washington Post, ...

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 ...

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 ...
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 ...
Botulinum neurotoxins (BoNTs) are extremely potent toxins that are capable of causing death or respiratory failure leading to long-term intensive care. Treatment includes serotype-specific antitoxins, which must be administered early in the course of the intoxication. Rapidly determining human exposure to BoNT is an important public health goal. In previous work, our laboratory focused on developing Endopep-MS, a mass spectrometry-based endopeptidase method for detecting and differentiating BoNT/A-G serotypes in buffer and BoNT/A, /B, /E, and /F in clinical samples. We have previously reported the effectiveness of antibody-capture to purify and concentrate BoNTs from complex matrices, such as clinical samples. Because some antibodies inhibit or neutralize the activity of BoNT, the choice of antibody with which to extract the toxin is critical. In this work, we evaluated a panel of 16 anti-BoNT/A monoclonal antibodies (mAbs) for their ability to inhibit the in vitro activity of BoNT/A1, /A2, and ...
