Chytridiomycosis is a disease caused by two pathogenic chytrid fungi, Batrachochytrium dendrobatidis (Bd) and B. salamandrivorans (Bsal). Snakes? The new research looked at what happens in a more real-life situation - when chytrid fungus is actually on a vulnerable frog. Theres a high probability that at least a dozen snake species disappeared from the area and perhaps many more, says Elise Zipkin, a study co-author and quantitative biologist at Michigan State University. Scheele chalks up the reliance on expert opinion to the fact that scientists are very much playing catch-up with the chytrid fungus. That means there are gaps in scientists' knowledge about some species, including this drab tree frog. Frogs and salamanders there can be found with these pathogens on their skin but they dont develop the disease because they have evolved with the fungus over a long time period. The disease is not known to affect humans. Moving down the food chain, removal of frog tadpoles has been shown to lead to more algae growth in streams, depriving them of oxygen. Take below precautions while visiting frog habitats in the wild, including nature pond, zoo or backyard gardens: The experimental treatments: These Include commercial antifungal products (itraconazole, steriplantN, mandipropamid, and PIP Pond Plus), Antimicrobial skin peptides of Pelophylax esculentus, microbial agents (Pedobacter cryoconitis), and heat therapy (at 35C for a day) are suggested. The first cases occurred in The Netherlands, as outbreaks in native fire salamanders, Salamandra salamandra. Its got to be affecting the birds and the mammals, and everything else, says Julie Ray, another co-author and an adjunct professor at the University of Nevada, Reno. Researchers are exploring using skin probiotics for amphibians, which adds beneficial microbes to the amphibians skin, that can help then fight off the pathogen. Afterward, despite intensive surveys over eight years, none were found. Before the fungus came through, researchers, including co-author Karen Lips at the University of Maryland, recorded seeing the animals 149 times. Its a familiar trope: The same fungus, How a zoo break-in changed the life of an owl called Flaco, Naked mole rats are fertile until they die, study finds, Why wetlands are so critical for life on Earth, Rest in compost? For amphibians, their skin is a very vital organ. I suspect there are likely additional predators and prey that have been impacted by the loss of amphibians, concurs Jamie Voyles, a biologist at the University of Nevada, Reno, who wasnt involved in the work.
