Fluorescence-based Evaluation of Cyclic di-GMP Levels in Pseudomonas aeruginosa.

The ability of Pseudomonas aeruginosa to establish chronic infections is associated with an effective switch from a motile to a sessile lifestyle. This proficiency is controlled by intracellular levels of the second messenger bis-(3'-5')-cyclic dimeric guanosine monophosphate (c-di-GMP). Targeting the c-di-GMP network could be a strategy to interfere with P. aeruginosa pathogenicity. Therefore, the development of tools to profile c-di-GMP intracellular levels is crucial. Here, we describe a protocol for the in vivo measurement of c-di-GMP levels in P. aeruginosa.
