Batrachochytrium salamandrivorans, or Bsal, is a recently discovered new member of the chytrid family of deadly pathogenic fungi affecting amphibians. True to the name, B. salamandrivorans affects salamanders rather than frogs, like the more well-known Batrachochytrium dendrobatidis, or Bd, chytrid fungus. This lethal fungus is thought to have originated from Southeast Asia but is now found in Asia, the Netherlands, Germany, and Belgium, spread by the pet trade. According to a Science paper published in 2015 by Yap et al., the largest U.S. ports for salamander import, and therefore the most vulnerable to Bsal introduction, are Los Angeles, CA; Tampa, FL; New York, NY; Atlanta, GA; and San Francisco, CA. The U.S. is the world’s salamander hotspot, with 50% of the world’s salamander species.

 

AmphibiaWeb recommends the following things you can do to protect salamanders:

  1. Avoid buying Asian salamanders until better precautions are in place.
  2. Never release pet salamanders into the wild, including those that you collected yourself and kept in captivity for at least 30 days.
  3. Treat waste water from tanks with bleach before pouring down the drain.
  4. Write your congress person to ask them to support the trade ban.
