these threats, various Mantella sp. are listed as least concern, near threatened, vulnerable, endangered, and critically endangered by the IUCN Red List of Threatened Species. Species in this genus have tested positive for Batrachochytrium dendrobatidis (Bd). As of yet, there have been no negative effects observed within amphibian populations in Madagascar, suggesting that the Bd strain has a low virulence level but should be closely monitored.
