Bacterial symbionts of amoebas help them survive bacterial infection, and prevent pathogens from spreading to others as much!
Microbe of the episode
Microbe of the episode: Eubacterium dolichum
In this study, the amoeba Acanthamoeba castellanii has another bacterial symbiont that helps it resist killing by the bacterial pathogen Legionella pneumophila. Once the amoebas recovered from the infection, they were more resistant to future challenges. Even better, the symbiont prevented the pathogen from transforming into a more spreadable form like it does when infecting amoebas alone.
