Due to the fungus' immense impact on amphibian populations, considerable research has been undertaken to devise methods to combat its proliferation in the wild. Among the most promising is the revelation that amphibians in colonies that survive the passage of the chytrid epidemic tend to carry higher levels of the bacterium "Janthinobacterium lividum". This bacterium produces antifungal compounds, such as indole-3-carboxaldehyde and violacein, that inhibit the growth of "B. dendrobatidis" even at low concentrations. Similarly, the bacterium "Lysobacter gummosus" found on the red-backed salamander ("Plethodon cinereus"), produces the compound 2,4-diacetylphloroglucinol that is inhibitory to the growth of "B. dendrobatidis".
