An article published in National Geographic April 2008 it was explained that scientists created human and alligator serum (protein-rich blood plasma that has had clotting agents removed) and exposed each of them to 23 strains of bacteria.  Human serum destroyed only 8 of the 23 bacterial strains. But the alligator serum killed all 23, including drug-resistant bacteria such as MRSA (methicillin-resistant Staphylococcus aureus).
In the National Geographic article the author stated that the study team though that pills and creams containing alligator or crocodile peptides would be available at local pharmacies within seven to ten years. Such products would be a boon to patients that need extra help preventing infections, such as diabetes patients with foot ulcers, burn victims, and people suffering from auto-immune diseases.
What the scientists didn't know is that John Sweet from South Africa had already started working on a skin balm made from the rendered fat of the Nile Crocodile. The product had launched in South Africa in 2005 and has been available in the USA since 2006. The product is called Repcillin and has been used to treat many skin conditions. Eczema in both adults and infants has shown a favorable response to Repcillin.
