Pseudomonas Aeruginosa (P. Aeruginosa) is a prevalent and opportunistic bacterium which frequently causes severe nosocomial infection. Current clinical detection methods are limited in terms of necessary time equipment. Increasingly, P. Aeruginosa’s electrochemically active virulence factor pyocyanin has facilitated its rapid detection, primarily through voltammetric such as cyclic voltammetry ...

P. aeruginosa is often preliminarily identified by its pearlescent appearance and grape-like odor in vitro. Definitive clinical identification of P. aeruginosa often includes identifying the production of both pyocyanin and fluorescein as well as its ability to grow at 42°C. P. aeruginosa is capable of growth in diesel and jet fuel, where it is known as a hydrocarbon-utilizing microorganism (or...

Previously it has been demonstrated that Staphylococcus aureus is sensitive toward Pseudomonas-secreted exotoxins, which preferentially target the electron transport chain in staphylococci. Here it is shown that a subpopulation of S. aureus survives these respiratory toxins of Pseudomonas aeruginosa by selection of the small-colony variant (SCV) phenotype. Purified pyocyanin alone causes the sa...
