Abstract.—Several studies have associated the
chytrid fungus Batrachochytrium
dendrobatidis with anuran population declines worldwide. To date,
the fungus has been found in Africa, the Americas, Australia, and Europe. However, it has never been reported to
occur in the Atlantic forest or Brazil. Based on morphological, histological, and molecular data, we encountered
evidence of B. dendrobatidis infection in a high-altitude stream-dwelling Brazilian anuran
magalhaesi (Leptodactylidae). One population (Municipality of
Camanducaia, State of Minas Gerais) was surveyed from 2001 to 2005. Tadpoles lacking teeth were observed and
collected in 2004. Histological and molecular analyses identified infection by B. dendrobatidis. Although infected
tadpoles seem nowadays to co-exist with the disease, our results are alarming due to the highly endangered
situation of the Brazilian Atlantic forest and its fauna. Effects of the chytrid infection on the studied
population are still unknown. Further investigations are needed to provide information on its distribution in
relation to other populations of H. magalhaesi.
