May 28, 2007 Botulism toxin is the deadliest poison on the planet. 2kg of it is enough to kill every person on the planet - although this doesn't stop the rich and tasteless from injecting it into their faces as Botox, where it stops nerves from working and has a slight smoothing effect on wrinkles. The toxin is produced by the Clostridium Botulinum bacteria - and scientists at the UK's Wellcome Trust Sanger Institute have just completed some fascinating genome research on the development of this incredibly effective killer and its survival mechanisms. Where some bacteria use complex and even elegant methods to dance around our immune systems, C. Botulinum goes for the direct hit with a "microbial sledgehammer." More please, just around the jawline.
