An Expert Meeting on The Current Scientific and Legal Status of Alternative Methods to the LD50 Test for Botulinum Neurotoxin (BoNT) Potency Testing was organised by the Centre for Documentation and Evaluation of Alternatives to Animal Experiments (ZEBET) at the Federal Institute for Risk Assessment (BfR), and took place on 27–28 April 2009, in Berlin, Germany. The goal of ZEBET is to promote p...
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 nov...
J Rehabil Med Suppl 41, 2003 DOI 10.1080/16501960310010151 Botulinum toxin is a potent neurotoxin produced by the bacterium Clostridium botulinum. There are seven serotypes, all of which block the release of acetylcholine from nerve endings, which gives the compound its theoretical base for reducing spasticity. Initial studies of the use of botulinum toxin in the management of spasticity were p...
BACKGROUND Since the first comprehensive description of the physiologic effects of botulism toxicity in the 1820s, specific formulations of botulinum neurotoxin type A (BoNT-A) have been developed. Now, a new botulinum neurotoxin type A formulation (BoNTA-ABO; Dysport [abobotulinumtoxinA]; Medicis Aesthetics, Scottsdale, AZ) has been made available in the United States and these same physiologi...
Botulinum neurotoxins (BoNTs) are some of the most poisonous natural toxins. Botulinum neurotoxins associate with neurotoxin-associated proteins (NAPs) forming large complexes that are protected from the harsh environment of the gastrointestinal tract. However, it is still unclear how BoNT complexes as large as 900 kDa traverse the epithelial barrier and what role NAPs play in toxin translocati...

Masseter muscle hypertrophy is a rare condition of unknown cause which is important in the differential diagnosis of head and neck masses, located in the cheek. Several treatment options reported for masseter hypertrophy, which range from simple pharmacotherapy to more invasive surgical reduction. Botulinum toxin type A is a powerful neurotoxin which is produced by the anaerobic organism Clostr...
botulism is a serious paralytic disease caused by clostridium botulinum toxin in foods. there are seven recognized serotypes of botulinum neurotoxins among which the principal prevalent types in humans include a, b and e. infant botulism results from intestinal colonization and toxin production by c. botulinum spores in babies less than 1 year old. honey is the most important food discriminated...
Introduction and purpose: Masticatory muscles hyperactivity is currently a very common problem among adult population. The ignorance of the symptoms lack or unsuccessful treatment may lead to serious health complications, which major focus on improvement standard therapy for bruxism. aim study was provide broad review promising bruxism with botulinum neurotoxin injections. Material method: cond...
BACKGROUND Botulinum neurotoxins are produced by Clostridium botulinum bacteria. There are eight serologically distinct botulinum neurotoxin isoforms (serotypes A-H). Currently, botulinum neurotoxin serotype A (BoNT⁄A) is commonly used for the treatment of many disorders, such as hyperactive musculoskeletal disorders, dystonia, and pain. However, the effectiveness of BoNT⁄A for pain alleviation...
