In a rare study, a researcher with the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology ( SOEST), determined the skin microbiome of an endangered frog was altered when the frogs were infected by a specific fungus, and it did not recover to its initial state even when the frog was cured of the infection.
