A környezeti hőmérséklet hatása a kétéltűek fertőző betegségeire

Abstract

Nowadays, we are facing the sixth mass extinction event, in which human activities are playing a decisive role. Amphibians are highly vulnerable because they are sensitive to rapid environmental changes. Emerging pathogens like Batrachochytrium dendrobatidis (Bd) and Ranaviruses (Rv) pose a serious threat to amphibians globally. Both are spreading mainly by human activities and causing massive declines among amphibian populations. Therefore, coinfections with these pathogens are frequently encountered in wild amphibian populations. Our study experimentally tested the effects of constant heat treatment on the disease progression of Bd and Rv with a particular focus on co-infections in Rana dalmatina tadpoles. The prevalence of Rv decreased significantly in tadpoles at the lower dose Rv and Bd coinfected group at 28 and 30 °C temperature.
