Chytridiaceae is a family of fungi that primarily infect amphibians. Some synonyms for Chytridiaceae are chytrids, chytrid fungi, and chytridiomycetes. The term chytrids is commonly used to refer to these fungi as a group, while chytridiomycetes is a more precise name associated with their taxonomic classification. Many different species of chytrids exist, and they vary in their specific host preferences and geographical distribution. While they have been identified as a major cause of amphibian declines worldwide, recent research is providing hope for the development of effective strategies to prevent and manage chytrid infections and conserve these vulnerable animal populations.
