It is a multidrug-resistant opportunistic human pathogen, a common cause of life-threatening nosocomial infections, and a key bacterial agent in cystic fibrosis and endocarditis. Strict anaerobes lack certain enzymes (including P. aeruginosa is a human and plant pathogen, it is largely opportunistic in nature which means infection tends to occur alongside existing illness or disease. Biofilm is an extracellular polysaccharide and protein matrix which provides an environment for large colonies to grow and thrive. All animals, plants, most fungi and some bacteria are obligate aerobes.
