and helminth parasite co-infection in invasive American bullfrogs in the Atlantic forest, Brazil.

Emerging infectious diseases threaten amphibian species across the globe. In Brazil, the American bullfrog () is a highly invasive species that can potentially transmit parasites and pathogens to native amphibians. This is the first assessment of co-infection of and helminth macroparasites in invasive populations of bullfrogs in South America.

High prevalence and concomitant infection of Ranavirus and Eustrongylides sp. in the invasive American Bullfrog in Brazil.

American Bullfrogs, Aquarana catesbeiana, are invasive anuran species distributed worldwide. One of the adverse impacts that this species causes in native communities is as a reservoir host for pathogens and parasites. Here, we report the coinfection of two pathogenic organisms in A.
