Genome of Clostridium botulinum reveals the background to world's deadliest toxin

...casing of insects and small crustaceans. It is not only animals that can feel the wrath of C. botulinum, explains Dr Sebaihia: "The soil can be a harsh environment and food can be scarce. To see off the competition, C. botulinum comes with its own ‘antibiotic’ — a chemical called boticin that kills c...
