QUOTE:  The deadly chytrid fungus is making devastating in-roads into Australia's vulnerable frog populations, with a Griffith University study revealing the disease-causing fungus is now established in frog populations throughout Eastern Australia... 

Kerry said that chytridiomycosis �?the disease caused by the fungus �?was likely absent from Queensland until 1978. It is now prevalent in moist, temperate areas around Australia, and around the world. Scientists theorize the rapid spread has been driven by international trade in amphibians as well as environmental factors. "Chytrid has spread so quickly that frogs often have no chance to evolve resistance to it," Kerry said.

"It's highly infectious, so when it arrives in an area most frogs are likely to contract it. It attacks the keratin in the frogs' skin, and may also produce a toxin that poisons the frog. The disease can have an 80 per cent mortality rate, and is already believed to be responsible for 6-8 species extinctions in eastern Australia.  "Overseas dozens of species have disappeared due to the disease..."  UNQUOTE.

NOTE:  Fungi create oxidizing conditions, which then prompt bacteria to become "clingly," causing "disease."  Also, fungi are usually not as sensitive to the damaging effects of oxidizing conditions as compared to other organisms.
