Eight strains of Clostridium botulinum type E out of twelve tested showed good growth and normal cell morphology in a synthetic medium containing choline. Growth and toxin production by a representative strain was not influenced by repeated subculturing. In the chemically defined medium, acetylcholine, N,N-dimethylethanolamine, and lecithin could replace choline to get normal cell division and ...

BACKGROUND Injections of botulinum toxin type A in the forehead have never been reported to cause hair side effects. OBJECTIVE The aim of this paper is to report a new type of alopecia, which we have seen in women undergoing periodic injections of botulinum toxin type A for forehead wrinkles, and to differentiate it from other types of hair loss. METHODS We conducted an observational study ...

Hyperhidrosis is an idiopathic condition of exaggerated sweat production resulting in dramatic impairments of daily activities, social interactions and occupational activities. The aim of the present study was to evaluate correlation between a subjective (Dermatology Life Quality Index) and an objective (Minor test) criterion and to assess difference in their levels over time in patients affect...

This is a retrospective case series describing the use of botulinum toxin type A in the treatment of children with congenital muscular torticollis who fail to progress with conservative management. A total of 27 children with congenital muscular torticollis, 6-18 mos of age, received 30 botulinum toxin type A injections into their sternocleidomastoid or upper trapezius muscle, or both, at a ped...

Neurotoxigenic Clostridium butyricum was isolated from the food implicated in an outbreak of clinically diagnosed type E botulism in China. PCR assay showed that the isolate (LCL 155) contained the type E botulinum toxin gene. This appears to be the first report of neurotoxigenic C. butyricum causing food-borne botulism.

Clostridium Botulinum Type E neurotoxin heavy chain consists of two domains: the translocation domain asthe N-terminal half and the binding domain as the Cterminal half (Hc). One effective way to neutralize botulinum neurotoxin is to inhibit binding of this toxin to neuromuscular synapses with antibodies against binding domain. Two synthetic genes, coding for Hc (the full length binding d...

Background: Use of botulinum toxin is becoming a popular way in treatment of some forms of strabismus.To evaluate the morphological changes in the orbital surface layer muscles of the rabbit eye following a single injection of botulinum toxin. Methods: 10 white Dutch rabbits weighing 2–3 kg received either 10 units (group 1; n=5) or 20 units (group 2; n=5) of botulinum toxin into the superior r...
