Antimicrobial Substances Identified in Komodo Dragon Blood
In a land where survival is precarious, Komodo dragons thrive despite being exposed to scads of bacteria that would kill less hardy creatures. Now in a study published in the Journal of Proteome Research, scientists report that they have detected antimicrobial protein fragments in the lizard’s blood that appear to help them resist deadly infections. The discovery could lead to the development of new drugs capable of combating bacteria that have become resistant to antibiotics...

Devil's Milk Could Be the Killer Ingredient in War on Superbugs
Devil's milk has proved to be an unlikely weapon in the increasingly desperate global fight against superbugs. Australian researchers have discovered that peptides contained in the milk of Tasmanian devils can kill some of the most deadly bacterial and fungal infections, including golden staph. Having scanned the devil's genome and discovered the six naturally occurring antimicrobial peptides, researchers from Sydney University set about replicating them artificially. They then tested the peptide's effectiveness at killing some of the most harmful bacteria known to humans...
