Tasmanian Devil Milk Kills Antibiotic-Resistant Superbugs Including Golden Staph

Scientists have discovered that Tasmanian devil milk contains antimicrobial peptides called cathelicidins that could eliminate antibiotic-resistant bacteria including methicillin-resistant Staphylococcus aureus (MRSA), also known as golden staph. These special peptides could also fight against the contagious Devil Facial Tumor Disease (DFTD) – a highly infectious parasitic facial cancer which has killed 80 percent of the wild Tasmanian devil in the past 20 years.

“These peptides are killing superbugs, so there is potential for future development into antibiotics,” said Emma Peel, lead author of the study, in a statement at ABC News. “That is the next step for our research, to see if these peptides have anti-cancer potential, if they are killing superbugs maybe they could kill the facial tumor.”

 Tasmanian devil milk can kill some of the world’s deadliest bacterial and fungal infections known to science, including golden staph

For the study, the team extracted the cathelicidin sequence from the Tasmanian devil genome and had peptides artificially made. The results showed the synthesized peptides were able to eliminate a number of pathogens, including the methicillin-resistant Staphylococcus aureus, otherwise known as golden staph. And, they were “3 to 6 times more effective” against a range of fungal infections than a common anti-fungal medication. The team also found that young devils do not do not catch the disease. This may have happened because the peptides evolved to help offspring grow stronger with a shield against DFTD, researchers believe.

The finding have been published in the journal Scientific Reports
