For decades, Burmese pythons have been ravaging Florida’s Everglades National Park and other ecosystems in the state. These invasive snakes were likely introduced to Florida from pet reptile importing.

Around the same time the invasive snake first showed up in Florida, a parasite known to be endemic in wild Burmese pythons also emerged: Raillietiella orientalis. Closely related to crustaceans and resembling a worm, R. orientalis infects the respiratory system, causing lung inflammation and breathing difficulties.

Parasites and host organisms often evolve together, giving hosts a chance to develop mechanisms for resisting the parasite. Burmese pythons went through a selective process with the parasite, which means the parasite isn’t as dangerous for them. But as a new pathogen for Florida’s wildlife, R. orientalis has proven to be deadly.
