Chytrid Fungus
Chytrid (pronounced “kit-rid”) fungus belongs to the Kingdom Fungi, Phylum Chytridiomycota, Class Chytridiomycetes, and Order Rhizophydiales, a division of zoosporic organisms. The fungus causes the disease chytridiomycosis, originally generated by Batrachochytrium dendrobatidis (Bd). An amphibian chytrid (discovered in 1998)—which causes an infection of the skin, with an affinity to frogs and toads—is present on every amphibian-inhabited continent. Further, broad lineage and genotypic variation have been found in B. dendrobatidis. The disease has resulted in a serious decline and extinction of more than 200 species of amphibians worldwide and poses the greatest threat to biodiversity of any known disease. By 2021, the fungus had pushed the regression of at least 501 amphibian species, or about one out of every 16 (6.3 …
