Frog Skin May Hold the Answer to Antibacterial Resistance

The CDC identifies antibacterial resistance as one of the top health threats of our time, with more than 2 million people getting an antibiotic-resistant infection each year. More than 23,000 people die each year from such an infection, driving a need to find a solution.

Scientists believe such a solution may exist in the form of bacteria from frog skin. A recent study found that an antifungal bacterium called Pseudomonas Cichorii could possibly be used to develop an alternative medication for those who have grown resistant to antibiotics. Pseudomonas Cichorii lives on the skin of frogs.


In addition to medicating humans, Pseudomonas Cichorii can also be used to help an epidemic affecting frog populations. Chytridiomycosis is a top cause of disease-related deaths worldwide. For the study, researchers traveled to Panama, where they gathered samples from seven different frog species in an effort to learn more about chytridiomycosis.

Once in the laboratory, scientists tested 201 different bacteria strains against a fungus called A. Fumigatus from patients with impaired immunity. They found that 29 of those strains had antifungal activity, but they were especially interested in Pseudomonas Cichorii, which they believe has the best potential to prevent the growth of A. Fumigatus.
