What is a possible role for quorum sensing in pathogenicity?
A) It detects and responds to the pH as an indicator of the environment.
B) It delays production of toxins that may alert the host to the presence of the bacteria.
C) It monitors and responds to concentrations of ions such as magnesium.
D) It senses and responds to the population of phagocytes at the infection site.
E) It helps the pathogen escape the adaptive immune response.

Question

Quizplus · Accepted Answer

Quorum sensing allows bacteria to coordinate their behavior based on cell density. In the case of pathogenic bacteria, it can delay the production of toxins until the population reaches a certain threshold, which may prevent the host from mounting an effective immune response. This can potentially increase the pathogenicity of the bacteria.
