Australian researchers are drawing blood from crocodiles because it contains an antibiotic so powerful, it may kill even the AIDS virus. A crocodile's immune system is incredibly efficient because these huge reptiles regularly engage in battles over territory that leave them wounded and even missing limbs. Despite this, crocs live a very long time.
Researcher Mark Merchant discovered the amazing properties of the crocodile immune system in 1998. Their blood contains antibodies that can even kill bacteria that has evolved to become resistant to penicillin, which is the last resort for sick patients. This is especially important at a time when superbugs are so prevalent in hospitals.
Scientists have tested the effect of croc blood on the HIV virus by mixing them together. The antibodies in the blood kill a large portion of the HIV cells. After many years of searching, scientists may have finally found a cure for AIDS.
