Analyzing the Interaction between Tetrahymena pyriformis and Bacteria under Different Physicochemical Conditions When Infecting Guppy Using the eDNA Method [PDF]

Animals
In the aquaculture system of ornamental fish, the interaction between bacterial microbiota and ciliate protozoa can prevent or promote disease outbreaks, and different physicochemical conditions will affect the relationships between them. We investigated

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

Scientific 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]

Frontiers 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 ...
