Abstract
La quitridiomicosis, una enfermedad causada por un agente patógeno fúngico, se ha convertido en la enfermedad infecciosa emergente responsable de la mayor pérdida de biodiversidad en la historia de nuestro planeta desde que se tienen registros históricos. Dicha enfermedad, ha afectado ya a más de 1000 especies de anfibios, ha jugado un papel principal en el declive de al menos 500 de esas especies, y ha convertido así a estos animales en la Clase de vertebrados más amenazada de la Tierra. Esta patología que afecta a la piel de los anfibios, está originada por el hongo quitridio Batrachochytrium dendrobatidis (de aquí en adelante, Bd) y afecta a multitud de especies principalmente de anuros. Hasta ahora Bd era el único miembro del Filo Chytridiomycota capaz de causar una enfermedad en vertebrados. No obstante, recientemente se ha descrito una nueva especie de hongo quitridio, Batrachochytrium salamandrivorans (de aquí en adelante, Bsal), que también muestra esta capacidad infectiva en vertebrados y que afecta más directamente a anfibios urodelos como las salamandras...
Chytridiomycosis, a fungal driven disease, has become the emerging infectious disease responsible for the greatest loss of biodiversity attributable to a disease in recorded history. It has already affected more than 1000 amphibian species and played a key role in the decline of at least 500 of those species, leading amphibians into becoming the most threatened vertebrate Class of our planet.This disease, which affects the amphibian skin mainly of Anuran species, is originated by the chytrid fungus Batrachochytrium dendrobatidis (here in after, Bd). Until now Bd was the only example of a chytrid infecting vertebrates. Recently though, a new chytrid fungus species has been described, Batrachochytrium salamandrivorans (here in after, Bsal), which also has this vertebrate infective capacity, mainly of Urodela species such as salamanders...
