I like the term "intercellular biodiversity" (much more than the old trope of "parasitism") #MicroSky
According to the microbial ecologist Puri López-García, pictured here at a salt flat in the Chilean Andes, some 25% to 50% of all bacterial cells may be parasites of other cells.
A Cell So Minimal That It Challenges Definitions of Life | Quanta Magazine
The newly described microbe represents a world of parasitic, intercellular biodiversity only beginning to be revealed by genome sequencing.
