Gastrotheca nebulanastes | Kosñipata Marsupial Frog

Amphibian News
A study by Burkart et al (2017) compared susceptibility of two species of Peruvian marsupial frogs to chytridiomycosis, caused by Batrachochytrium dendrobatidis (Bd), and found that Gastrotheca nebulanastes (or Kosñipata Marsupial Frog) is susceptible, whereas its congener, Gastrotheca excubitor (or Abra Acanacu Marsupial Frog), is resistant. The study compared the anti-Bd abilities of cutaneous defenses, including skin bacteria and skin peptides, between the two species and found that bacteria, but not peptides, differed between the two species in their ability to inhibit Bd growth. The results highlight the importance of anti-Bd skin bacteria in providing frog species with protection from Bd and may inform mitigation strategies for other wildlife diseases.
