Researchers at McNeese State University believe alligators could hold thekey to healing humans.

At the helm of the study is Dr. Mark Merchant, professor of biochemistry.

Merchant saidhis interest with gators began at an early age.

"I grew up in the marshes of Southwest Louisiana and Southeast Texas hunting and fishing and I am still in the marsh a lot pursuing those activities. I've been around alligators most of my life," Merchant said.

Merchant said he realized a long time ago that there was something special about the immune systems of theseprehistoric animals.

"Alligators and crocodiles are very territorial and they fight andat times, inflict great injury on one another butthe fact is it seems they heal rather rapidly despite the fact they live in an environment wherethere are lots of potentially infectious microbes such asbacteria and fungi and things that can infect these massive wounds," Merchant said.

When his research began 11 years ago, Merchantwas able to prove the blood of alligators could kill pathogens. Since then, he has learned more howalligator blood kills bacteria, fungi and viruses, specifically white blood cells.

"What we have found in the last four or five years is that the white blood cells from alligators can and other crocodilians around the world make these tiny peptides that have tremendous antibacterial and antifungal activity," explained Merchant. "We have just recently isolated the small peptides or proteins and are working to determine the exact structure. So we think we potentially may have not only a new antibiotic, but a whole new class of antibiotics for human and veterinary use."

Merchantsaid there is still a lot of researchbeforethe antibioticcan be produced inlabs.

"It could be tomorrow. It could be next month or it could be in 10 years. I hope it is sooner rather than later," he said.
