The Chytrid fungus (Batrachochytrium dendrobatis) is a recognized global threat worldwide affecting numerous species of amphibians. Frogs and toads of Pampa's grasslands are not an exception. Chytrid fungus has been documented in several species of toads and frogs in Pampa grasslands, including endemic threatened species as the Tandilean red-belly toad (Melanophryniscus aff. montevidensis), and the Argentine horned frog (Ceratoprhys ornata).

Several solutions have been proposed to control Chytrid fungus, including the use of chemical compounds. For example, the chloramphenicol showed to be lethal to the fungus in laboratory conditions. However, the use of chemical compounds in wild places has not been tested yet.

In this project we will conduct a preliminary experience by testing the use of two chemical compounds (i.e. chloramphenicol and colloidal silver) in experimental ponds. We are looking for an effective & eco-friendly treatment to control the Chytrid fungus.
