Infectious bacteria use quorum sensing to determine when to attack a host

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that infectious bacteria use quorum sensing to determine when to attack a host?

Yes. Infectious bacteria utilize quorum sensing—a cell-density-dependent communication system—to coordinate gene expression, biofilm formation, and the deployment of virulence factors during host infection.

Verdict: SUPPORTED · 3 sources for, 0 against · Last checked

The analysis

The retrieved literature consistently supports the claim that infectious bacteria use quorum sensing as a cell-density-dependent communication network to coordinate virulence factor production, biofilm formation, and overall pathogenesis during host infection. There are no papers refuting this well-established microbiological mechanism.
