Willaertia /ˈwɪləɹʃə/ is a genus of non-pathogenic, free-living, thermophilic amoebae in the family Vahlkampfiidae. Originally discovered in 1984 by Johan De Jonckheere, their life cycle, like that of other heteroloboseans, has been found to alternate between 3 distinct stages: a cyst, amoeba, and temporary flagellated stage. Willaertia lives in a variety of environments and in recent years has been researched to potentially become a biocide for Legionella pneumophila.
