Cím:Species composition and chytridiomycosis infection of the Pelophylax esculentus complex (Anura: Ranidae) in the Hortobágy National Park, Hungary / Dávid Herczeg, Judit Vörös
Megjegyzések:Chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), is anemerging infectious disease implicated in declines of amphibian populations around theglobe. In Hungary the presence of the chytrid fungus from elevated habitats was documentedbefore but little is known about the distribution in the lowlands. The Western Palearcticwater frogs of the genus Pelophylax include a series of about 12 morphologically similar speciesin Europe. The Pelophylax species complex consists three species in Hungary: P. ridibundus,P. lessonae and the hybrid P. kl. esculentus. Our sampling area situated in the HortobágyNational Park and we collected 29 Pelophylax spp. from two localities associated with flowingwater and 30 specimens from the area of fish ponds and from there additionaly non-invasivesamples (19) becoming from skin swabbing. We used newly developed primers for distinguishingamong the water frog species, and real-time PCR for detecting the Bd zoospores.Based on our molecular taxonomy findings the species composition of the investigated populationsof water frogs consists the P. ridibundus and the hybrid P. kl. esculentus. Our resultsclearly showed that the population of water frogs connected with flowing water were infectedwith Bd, while the population inhabiting the fish ponds were uninfected. The prevalence was18.9% for the whole population together, while 51.7% for the frogs from the flowing water.Prevalence was 37.1% for P. ridibundus and 8.3% for P. kl esculentus. The mean intensity was10.13 GE (genome equivalent zoospore quantity).
