a bacterial species found in soil, water, and commonly in clinical specimens (wound infections, infected burn lesions, urinary tract infections); the causative agent of blue pus; occasionally pathogenic for plants; usually causes infections in humans in whom there is a defect in host defense mechanisms.

pseudomonas aeruginosaA normal soil inhabitant and human saprobe/commensal which may contaminate various solutions and fluids in a hospital, causing opportunistic infection in immunocompromised patients.
Infective endocarditis in IV drug users, respiratory tract infections, urinary tract infections, bacteraemia, meningitis, “malignant” external otitis.
Aminoglycosides—e.g., gentamicin, amikacin, netilmicin, tobramycin, etc.
Pseudonomas aeruginosa is both invasive and toxicogenic, and infects patients in a 3-step process:
1. Bacterial attachment and colonization—mediated by pili and antiphagocytic effects of the organism’s polysaccharide capsule;
2. Local invasion—mediated by elastase and bacterial alkaline protease; and
3. Dissemination—high-dose tobramycin delivered by aerosol is reportedly effective in patients with cystic fibrosis.
