Botulism due to type F botulinum neurotoxin (BoNT/F) is rare (<1% of cases), and only a limited number of clostridial strains producing this toxin type have been isolated. As a result, analysis of the diversity of genes encoding BoNT/F has been challenging. In this study, the entire bont/F nucleotide sequences were determined from 33 type F botulinum toxin-producing clostridial strains isolated...

BACKGROUND On 7 and 11 July 2007, health officials in Texas and Indiana, respectively, reported 4 possible cases of type A foodborne botulism to the US Centers for Disease Control and Prevention. Foodborne botulism is a rare and sometimes fatal illness caused by consuming foods containing botulinum neurotoxin. METHODS Investigators reviewed patients' medical charts and food histories. Clinica...

Personal experience is discussed in the use of botulinum neurotoxin injections into both parotids, performed in order to transiently reduce salivation in patients undergoing major ablative and ablative-reconstructive oncologic surgery for head and neck tumours. Overall, 8 adult patients (2 female, 6 male) have been treated. Six cases were affected by pharyngocutaneous fistulas, one by severe si...

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 ...

objective botulism is the acute, descending, flaccid paralysis that results when the neurotoxin of clostridium botulinum blocks neuromuscular transmission. c botulinum toxin is the most poisonous substance that blocks neuromuscular transmission and causes death through airway and respiratory muscle paralysis; all forms of botulism manifest neurologically as asymmetric, descending, flaccid paral...

The clinical eVects of botulinum toxin have been recognised since the end of the 19th century. It is the most potent neurotoxin known and it is produced by the gram negative anaerobic bacterium Clostridium botulinum. The paralytic eVect of the toxin is due to blockade of neuromuscular transmission. Injection into a muscle causes chemodenervation and local paralysis and this eVect has led to the...

Botulinum neurotoxins are natural molecules produced by anaerobic spore-forming bacteria called Clostradium boltulinum. The toxin has a peculiar mechanism of action by preventing the release of acetylcholine from the presynaptic membrane. Consequently, it has been used in the treatment of various neurological conditions related to muscle hyperactivity and/or spasticity. Also, it has an impact o...

Foodborne illnesses represent a substantial cause for disease among the population. The Norwegian fermented fish is traditional way of conserving during winter. If wrongly prepared or stored, contaminated with Clostridium botulinum may be neurotoxin due to favorable conditions anaerobic bacterium. classical form botulism ingestion preformed in food that has been spores.
