Amphibians Infected by Ranavirus Found in Atlantic Rain Forest

Researchers have found bullfrog tadpoles with clear signs of infection by ranavirus in Brazil. The specimens were collected from two ponds in the city of Passo Fundo, south of the country (state of Rio Grande do Sul), in November 2017. Ranavirus causes skin ulcerations, edema, and internal hemorrhage. It does not affect humans but can be lethal to amphibians and fish.
