Botulinum toxin injection into the pylorus is reported to improve gastric emptying in gastroparesis. Classically, botulinum toxin inhibits ACh release from cholinergic nerves in skeletal muscle. The aim of this study was to determine the effects of botulinum toxin on pyloric smooth muscle. Guinea pig pyloric muscle strips were studied in vitro. Botulinum toxin type A was added; electric field s...

In USA, the potency of commercial vaccines containing Clostridium botulinum type C toxoid is determined by a mink vaccination-challenge assay outlined in the Code of Federal Regulations, Title 9, Part 113.110. A more humane potency test is desired, and this study provides preliminary data in support of a serological assay that correlates post-vaccination antitoxin titers of guinea pigs to vacci...

The genetic relatedness of Clostridium botulinum type E isolates associated with an outbreak of wildlife botulism was studied using random amplification of polymorphic DNA (RAPD). Specimens were collected from November 2000 to December 2008 during a large outbreak of botulism affecting birds and fish living in and around Lake Erie and Lake Ontario. In our present study, a total of 355 wildlife ...
