Although botulism can cause severe and prolonged symptoms, most people recover completely from the illness. Scott A.B.

BoNT/EA was also found to block the release of the capsaicin-evoked pro-inflammatory calcitonin gene-related peptide (CGRP) [54] and thus a potential treatment for migraine type headache [62]. + Nm 1980, Alan B Scott s dng botulinum type A trn ngi iu tr bnh l mt. We analyzed time-to-onset and duration of BoNT efficacy in 186 consecutive patients treated with BoNT for blepharospasm, cervical dystonia, facial hemispasm, oromandibular dystonia, limb dystonia, and sialorrhea due to Parkinsonism. discovered a novel eighth serotype of BoNT, which is isolated from the C. botulinum strain 111 through a bioinformatics approach [57]. Botulism is caused by a toxin that attacks the body's nerves and causes difficulty breathing, muscle paralysis, and even death. Among these, BoNT/E has rapid onset but a short duration of action (24 weeks) [36]. Interestingly, the size of the toxin complex also varies across formulations. y l 1 xt nghim chuyn su ca chuyn ngnh thn kinh, rt quan trng trong chn on tn thng sm ca ng c botulinum cng nh chn on phn bit nhng bnh l c biu hin bnh tng t. ) Gip chn on sm nht c th (ghi in c) & kim sot tnh trng suy h hp sm.

These developments are important not only from the perspective of quality assurance but because of the potential to produce designer drugs; by altering genetic sequences, it is theoretically possible to change the toxo-pharmacological properties of the toxins, and thus, non-toxic BoNTs could be engineered to produce vaccines or toxoids [36].
