Researchers in Australia have found that the blood of crocodiles contained antibodies that could kill penicillin-resistant bacteria (e.g. Staphylococcus aureus or golden staph) and the HIV virus.
A crocodile’s immune system is said to be much more powerful than a human’s immune system, preventing life-threatening infections after territorial fights which often leave the crocodiles with wounds and missing limbs.
Yet, the crocodile’s immune system may be too powerful for humans and may need to be synthesized for human consumption.
