Amphibians, such as frogs and salamanders, are susceptible to various diseases that can threaten their populations. One of the most significant diseases is chytridiomycosis, caused by the fungus Batrachochytrium dendrobatidis. This disease affects the skin of amphibians, leading to severe health issues and often resulting in death. Another notable disease is ranavirus infection, which can cause high mortality rates in amphibian populations. Ranaviruses can infect multiple species and lead to symptoms like swelling, lesions, and lethargy. The spread of these diseases is often linked to habitat loss, climate change, and the introduction of non-native species.
