　　The most serious type of injury to frogs and their relatives is Reno Quitolide. This deadly fungus can infect almost amphibians, erode the skin and cause heart disease. New research now points out that frogs will develop some important immunity that can prevent such frogs from surviving after repeated exposure to mold. Although this conclusion is preliminary, the results of the study indicate that there may be ways to protect these vulnerable amphibians.

　　To study how frogs resist chitosan in frogs, ecologist Jasonohr and colleagues at the University of South Florida used two Florida-friendly frogs (oak toad and Cuban tree frog) as research targets. First, the researchers investigated whether frog toads can learn to avoid frog chitosan. They created a small room in the laboratory and placed the frog mold next to it. When the oak toads were put into the hut for the first time, they stayed on both sides of the hut for the same amount of time. Later, Roll removed the oak tree toad and killed the frog gourd in the heat. When the toad of the same orc returned to the hut, they did not want to stay on the side of Kitrid where the frog was once.

　　In short, I can learn how to avoid Kitrid the frog. Rohr is doing another experiment to find out how the frog detects the frog's chitin, but he is sure that the frog must be in pain when attacked by the frog. Other experiments on these two species also showed that every time the frog is exposed to chitin, the frog’s immune system is enhanced. When the frog's chitosan was first contacted, the number of frog's immune cells doubled. In addition, the proportion of surviving amphibians has increased. Only 20% of the frogs exposed to citcito for the first time survived, and more than half of the frogs survived in the fourth "match".
