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 ...

Botulinum neurotoxin (BoNT) is a protein toxin (approximately 150 kDa), which possesses a metalloprotease activity. Food-borne botulism is manifested when BoNT is absorbed from the digestive tract to the blood stream and enters the peripheral nerves, where the toxin cleaves core proteins of the neuroexocytosis apparatus and elicits the inhibition of neurotransmitter release. The initial obstacl...

Many emerging and reemerging bacterial pathogens synthesize toxins that serve as primary virulence factors. We highlight seven bacterial toxins produced by well-established or newly emergent pathogenic microbes. These toxins, which affect eukaryotic cells by a variety of means, include Staphylococcus aureus alpha-toxin, Shiga toxin, cytotoxic necrotizing factor type 1, Escherichia coli heat-sta...

The Botulinum Neurotoxins are produced by the anaerobic bacterium Clostridium botulinum and are considered the most potent toxins known and its application has become useful and significant in the treatment of oral and maxillofacial injuries. The aim of this study was to review the literature showing the possible therapeutic uses of botulinum toxin in dentistry. There were used articles, that d...

Clostridum species produce seven serotypes (A-G) of botulinum toxin, four of which (A, B, E, and F) are normally associated with human illness. To date, the most reliable test for botulinum toxin is the mouse bioassay. The authors' laboratory has been exploring the use of an antibody-based assay similar to an enzyme-linked immunoabsorbant assay (ELISA) but utilizing electrochemiluminescent tech...

BACKGROUND The frontiers of clinical medicine constantly expand as a result of the innovative efforts of visionary researchers and keen observations of seasoned clinicians. In medicine, rarely has a therapeutic agent been found efficacious in the management of so many symptoms and in such a relatively short time as botulinum toxin. One of the most notable contributions of botulinum toxin therap...
