Treating a Bsal Infection of Pet Salamanders

This video is about the treatment of a Bsal (Batrachochytrium salamandrivorans) infection in one of my fire salamanders. Luckily, pet salamanders can be treated quite easily with great chance of success. For more information watch the videos. :)

General Information on Bsal:

"Batrachochytrium salamandrivorans (Bsal) is a pathogenic chytrid fungus that infects amphibian species. Although salamanders and newts seem to be the most susceptible, some anuran species are also affected. Bsal has emerged recently and poses a major threat to species in Europe and North America.

It was described in 2013 based on a strain collected from skin tissue of fire salamanders Salamandra salamandra. The pathogen, unidentified up to then, had devastated fire salamander populations in the Netherlands. Molecular phylogenetics confirmed it as related to the well known chytrid B. dendrobatidis. Like this species, it causes chytridiomycosis, which is manifested in skin lesions and is lethal for the salamanders. Damage to the epidermal layer can be extensive and may result in osmoregulatory issues or sepsis.
Batrachochytrium salamandrivorans, clinical signs and pathology
Another study estimated that this species had diverged from B. dendrobatidis in the Late Cretaceous or early Paleogene. While initial susceptibility testing showed frogs and caecilians seemed to be resistant to Bsal infection, it was lethal to many European and some North American salamanders. East Asian salamanders were susceptible but able to tolerate infections. The fungus was also detected in a more-than-150-year-old museum specimen of the Japanese sword-tailed newt. This suggests it had originally emerged and co-evolved with salamanders in East Asia, forming its natural reservoir, and was introduced to Europe rather recently through the trade of species such as the fire belly newts as pets. The asian origin hypothesis for Bsal is supported by additional studies which have found Bsal in wild urodela populations in Asia and in animals of asian origin being transported via the pet trade. Since the pathogens initial discovery, it has been found in several additional areas across Europe in both wild and captive populations. One study was able to detect Bsal in 7 of 11 captive urodele collections.

The description of this pathogen and its aggressiveness raised concern in the scientific community and the public, fearing that it might be a rising threat to Western hemisphere salamanders. On January 12, 2016, the U.S. government issued a directive that prohibited the importation of salamanders in order to reduce the threat posed by B. salamandrivorans."
