I am reaserching the local secies of frogs in Maumee, Ohio.
I've heard that frogs have antibiotics in their skin. What
advantage would this serve if this is true?
There is a peptide body in the skin of frogs and other amphibians.
This peptide fights infection if the animal is injured. It works
differently than antibiotics like penicillin does. Antibiotics we
take find the bacteria and shut it down, kind of like turning off
a system on a computer. The computer can find a way to turn it back
on. The peptide body finds the bacteria and punches a hole in it. This
would be like taking a hammer to the computer! This means that the
bacteria cannot grow a resistance to the peptide body, so the bacteria
would not become immune to it, letting this new peptide body antibiotic
work forever! If it can be harnessed and used correctly, it would offer
people a much better alternative to the antibiotics we have now.
