The free-living ciliate Tetrahymena pyriformis inactivates engulfed influenza A(H1N1)pdm09 virus via two distinct types of endosomes [PDF]

open access: yesScientific Reports
Wild aquatic birds are a major reservoir of the influenza A virus in natural ecosystems, facilitating its entry into the aquatic microbial food web through their feces. Free-living protozoa and particularly bacterivorous ciliates are essential players of

Single-cell RNA-seq reveals a key role for Vibrio cholerae Mak toxins in Tetrahymena pyriformis killing and bacterial survival [PDF]

open access: yesFrontiers in Microbiology
In the environment, Vibrio cholerae employs multiple strategies to resist predation by heterotrophic protozoa. For example, V. cholerae biofilms release toxic compounds, such as ammonium and pyomelanin, which can kill protists, such as Tetrahymena ...
