"They tear limbs off each other and despite the fact that they live in this environment with all these microbes, they heal up very rapidly and normally, almost always without infection,"
Wired News: Antibiotics From Crocodile Blood?: "SYDNEY -- Scientists in Australia's tropical north are collecting blood from crocodiles in the hope of developing a powerful antibiotic for humans, after tests showed that the reptile's immune system kills the HIV virus.
The crocodile's immune system is much more powerful than that of humans, preventing life-threatening infections after savage territorial fights which often leave the animals with gaping wounds and missing limbs."...
"If you take a test tube of HIV and add crocodile serum it will have a greater effect than human serum. It can kill a much greater number of HIV viral organisms," Britton said from Darwin's Crocodylus Park, a tourism park and research center.
Britton said the crocodile immune system worked differently from the human system by directly attacking bacteria immediately an infection occurred in the body.
"The crocodile has an immune system which attaches to bacteria and tears it apart and it explodes. It's like putting a gun to the head of the bacteria and pulling the trigger," he said.
