Frog Skin Offers New Therapy Against Bacterial Infections

A naturally occurring agent in frog skin may inhibit multi-drug resistant bacterial strains.

Researchers have identified antimicrobial peptides (AMPs) as a promising candidates for therapeutic use, and they have found amphibian skin to be one of the richest sources of such AMPs.

Five AMPs from three different frog and toad species were tested for antibacterial activity against multi-drug resistant strains. Initial results showed that all the peptides acted as antibacterial agents. A peptide called esculentin 1b produced an antibacterial response within 2 to 20 minutes of exposure.
