Tetrahymena
Sign in to saveTetrahymena is a genus of free-living ciliates, examples of unicellular eukaryotes. The genus Tetrahymena is the most widely studied member of its phylum. It can produce, store and react with different types of hormones. Tetrahymena cells can recognize both related and hostile cells.

四膜蟲（Tetrahymena）是自由游離生活的(非寄生性的)纤毛原生動物，也可以從偏利共生轉變為病原生存模式。 它們在淡水池中很常見。在生物醫學研究中用作模式生物的四膜蟲屬是嗜熱棲熱菌(T. thermophila)和熱厭氧桿菌(T. pyriformis)。

Tetrahymena is a genus of free-living ciliates, examples of unicellular eukaryotes. The genus Tetrahymena is the most widely studied member of its phylum. It can produce, store and react with different types of hormones. Tetrahymena cells can recognize both related and hostile cells.
Tetrahymena are commonly endosymbiont hosts to green algae, from which it receives oxygen, helping the host organism survive in anoxic environments. They are common in freshwater lakes, ponds, and streams.
