Komodo dragon blood might help fight a growing human threat


Komodo dragons are one of the fiercest predators on Earth, and now, researchers think the lizards' blood could help humans fight off one of our biggest threats: antibiotic resistance.

Every time you use antibiotics, some bacteria survive, and they reproduce and build immunity to the drugs. The issue is reaching dangerous levels across the globe as antibiotics are overused.

On the flip side, Komodo dragon saliva is filled with bacteria, yet their blood has an innate ability to fight infections.

Researchers at George Mason University mimicked a molecule in that blood to create a compound that could fight infections in people.

So far, it's only been tested on mice, but the compound did beat two antibiotic-resistant strains of bacteria.

More testing is needed, but the researchers think it could eventually work on people and treat more strains than just those two.

Beyond antibiotic resistance, wounds healed faster with the compound's help. If it gets cleared for human use, the compound could also be applied to drugstore bandages to help with simple cuts.

Stephanie Hall (L), sits on the couch with her sister, Crystal Silva (R), and their ten year old niece Destini and nephew Kane in El Paso, Texas, U.S. on July 2, 2016. The children's mother, Natalie Silva, contracted Methicillin-resistant Staphylococcus aureus, more commonly known as MRSA, a skin infection that can turn fatal once it enters the bloodstream, when she went to the hospital to deliver Kane. After a 10 month battle with MRSA, Silva died, leaving Hall and the family to raise the two children. TO MATCH SPECIAL REPORT USA-UNCOUNTED/SURVEILLANCE REUTERS/Dan Dalstra

A sample bottle containing E. coli bacteria is seen at the Health Protection Agency in north London March 9, 2011. For decades scientists have managed to develop new medicines to stay at least one step ahead of the ever-mutating enemy, bacteria. Now, though, we may be running out of road. Methicillin-resistant Staphylococcus aureus, commonly known as MRSA, alone is estimated to kill around 19,000 people every year in the United States -- far more than HIV and AIDS -- and a similar number in Europe, and other drug-resistant superbugs are spreading.
