An ancient Russian way to keep milk from going sour was to
put a frog in the bucket of milk. This little trick has scientist trying to
figure out why it was able to be effective. Amphibians have an antimicrobial
substance called peptides that are throughout their skin. This substance is a
first line defense to fight against bacteria and other microorganisms that
would in the frog environment. A prior study reveals that the skin of a Russian
Brown frog contains 21 different substances carrying antibiotic and potentially
could have other medical properties.
