World's Amphibians Face Another Fungal Threat

Although this blog is mostly dedicated to humanity and its liberation, I also value animals and their right to life. If nothing else, we can learn a lot from the study of animals. In nature, things have their place and that includes species of animals. Here we see that many of the worlds salamanders are threatened with extinction. As with all animals - they may hold the key to overcoming human diseases. For example, salamanders can regenerate limbs when they are lost. Their study may point to ways in which humans can someday grow back lost limbs, such as arms or legs.
I like salamanders. I have had some as pets and they get quite tame and are amazingly adoptive.

More than 200 frogs, toads, and other amphibian species around the world are threatened by a lethal skin disease caused by the chytrid fungusBatrachochytrium dendrobatidis (Bd). Last year, a related pathogen was discovered decimating populations of fire salamanders in the Netherlands and Belgium. The new microscopic killer, known as B.salamandrivorans (Bs), is only the second known species of its kind found to infect vertebrate hosts.  
Now, an analysis of more than 5,000 amphibians from four continents suggests that Bs may have spread from Asia to Europe through pet trade. The results, published today (October 30) in Science, also reveal the extent to which other amphibian species are vulnerable to the fungus. So far, European newts and salamanders appear to be the most severely affected.
The study “is a stunning confirmation of the original paper that came out a year ago, which reported for the first time this pretty much salamander-specific fungus,” said zoologist David Wake of the University of California, Berkeley, who was not involved with the work.
