Pseudomonas aeruginosa is an opportunistic pathogen, meaning that it exploits some break in the host defenses to initiate an infection. aeruginosa genes were significantly altered in response to bleach by twofold or more (471 upregulated, 630 downregulated). Cyclic AMP is produced by two adenylate cyclases, CyaA and CyaB, with CyaB responsible for the majority of cAMP production. We found that PQS production was not a universal signaling response to antibiotics as. You would then create power point presentation defending your tests and results.
