The ‘ranavirus’, a pathogen that attacks amphibians severely and is known to scientists as “The amphibian coronavirus”, it is spreading “in a dizzying way, with outbreaks and massive mortalities throughout the Peninsula ”, especially the northern zone, according to the Mixed Biodiversity Research Unit of the Higher Council for Scientific Research, in collaboration with the Aranzadi Science Society and the Alavés de la Naturaleza Institute.
They report that analyzes on samples of webbed newt specimens that appeared lifeless in the Upper Nervión, in the vicinity of the Izki Natural Park, denomination of the Cuadrilla de la Montaña Alavesa, have tested positive for this virus, which “produces hemorrhages and necrosis “, and that in addition to affecting amphibians is also capable of damaging reptiles and fish.
The remains obtained by scientists have confirmed that the animals they were positive for this disease.
The Aranzadi Science Society explains that this disease is spreading in various areas of the country, as well as protected areas as in unprotected places, but to a greater extent in the north.
Some experts in the field relate this expansion of the disease to the deterioration of the environment that favors the proliferation of zoonoses.
Researchers insist on the importance of conducting a monitoring of these threatened species for this disease.
