Threats to Frogs

Threat to Frogs: Diseases

Just like us humans, frogs and other amphibians can become sick from diseases. Here are some of the most known diseases for frogs.


Red Leg Syndrome is caused by the capillaries stretching and even bleeding out under the frogs skin.  Untreated, this can lead to the frog’s death. This disease is often found in captive amphibians.  The bacteria Aeromonas hydrophila is one of the most common culprits of getting the amphibian sick but there are other bacteria that can cause red leg syndrome too. 


Ranavirus is responsible for large die offs of frogs, other amphibians, and turtles. Ranavirus is a genus of viruses from the family Iridoviridae. Ranavirus is believed to be found in every state besides maybe Hawaii.  Its found in North America, South America, Europe, Asia, and Australia. One of the easy signs to see of Ranavirus is red skin hemorrhages.

Chytrid Fungus is maybe the worst disease out there. I wrote a full post on it so I’ll just link that here
