Classification of intestinomotor drugs by means of type D botulinum toxin

Botulinum toxin type B micromechanosensor.

Botulinum neurotoxin (BoNT) types A, B, E, and F are toxic to humans; early and rapid detection is essential for adequate medical treatment. Presently available tests for detection of BoNTs, although sensitive, require hours to days. We report a BoNT-B sensor whose properties allow detection of BoNT-B within minutes. The technique relies on the detection of an agarose bead detachment from the t...

Activation of Clostridium botulinum type E toxin by trypsin.

Since 1936, when the type E strain of Clostridium botulinum was first established as a result of the work of Gunnison et al. (1936), 17 outbreaks of Type E botulism have been reported, involving 69 persons, of whom 21 died (Dolman and Chang, 1953; Dolman et al., 1955). Although the large proportion of fatalities suggests that this organism is highly toxigenic, published reports indicate that in...

Transdermal Delivery of Clostridium Botulinum Toxin Type a by Iontophoresis

Molecular weight of type a botulinum toxin.

Clostridium botulinum type A does not produce a 12,000 molecular weight toxin. The reported isolation of such a material by Gerwing et al. could not be confirmed.

Botulinum toxin type B for dynamic glabellar rhytides refractory to botulinum toxin type A.

BACKGROUND Botulinum toxin type B (BTX-B; Myobloc) has recently been introduced for the treatment of dynamic rhytides. This serotype is structurally similar to botulinum toxin type A (BTX-A; Botox) and appears to produce equivalent muscular paralysis. Because of the fact that some patients may become resistant to the effects of BTX-A with its continued use or may require large doses of type A t...
