Botulism is a dangerous neuroparalytic illness caused by a botulinum toxin that is a product of the Clostridium botulinum bacteria. This toxin invades neuromuscular junctions by blocking the release of acetylcholine and results in lack of muscle contraction. According to Centers for Disease Control and Prevention‚ “There are three main kinds of botulism: foodborne botulism‚ infant botulism‚ and wound botulism. Foodborne botulism occurs when a person ingests the toxin within food that leads to illness

Identification and characterization of Pierisin gene in P. napi The strategy was followed to amplify the Pierisin-6 gene was given in the supplementary Fig. 1. The mRNA of pierisin-6 gene was purified from the total RNA of fifth instar larvae of P. napi‚ the conserved region was amplified using gene specific primers (supplementary table-1)‚ cloned into pGEM®-T vector and sequenced. Further‚ 3’ and 5’ untranslated regions of pierisin-6 gene were identified by 3’/5’ RACE-PCR. The amplified cDNA sequence

Botulinum toxin is one of the most deadly substances known to humanity; it is a neurotoxin generated from the bacterium Clostridium botulinum. The toxin interferes with neurotransmission of the brain‚ causing paralysis throughout the body. Botulinum is also used clinically‚ but is very unstable; more information is needed about the toxin in order to move further in
