Chytridiomycosis

Definition

Chytridiomycosis is an infectious disease caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd). It affects amphibians, leading to significant population declines and threats to biodiversity.

5 Must Know Facts For Your Next Test

1. Chytridiomycosis primarily impacts amphibians, including frogs, toads, and salamanders.
2. The disease disrupts the skin's ability to regulate water and electrolyte balance, often resulting in death.
3. First identified in the late 20th century, chytridiomycosis is now present on every continent except Antarctica.
4. The spread of Bd is facilitated by global trade and movement of amphibian species.
5. Conservation efforts are focused on captive breeding programs, habitat protection, and research on potential treatments.
