A sloth hangs from a tree branch at the Sloth Sanctuary and Rescue Shelter in Cahuita, Limon Province, Costa Rica, on March 10, 2023. - The fur of the Costa Rican sloth can produce antibiotics that keep at bay pathogens tha could make the tropical animal sick. Now, scientists wonder whether they could apply this to humans. Max Chavarria, a researcher at the University of Costa Rica, found in the notoriously lazy mammals' fur a unique mix of insects, fungi, algae and bacteria creating a delicately balanced biome that keeps sickness away.

THE fur of Costa Rican sloths appears to harbor antibiotic-producing bacteria that scientists hope may hold a solution to the growing problem of "superbugs" resistant to humanity's dwindling arsenal of drugs.
