Human targets of Pseudomonas aeruginosa pyocyanin.
Pseudomonas aeruginosa produces copious amounts of the redoxactive tricyclic compound pyocyanin that kills competing microbes and mammalian cells, especially during cystic fibrosis lung infection. Cross-phylum susceptibility to pyocyanin suggests the existence of evolutionarily conserved physiological targets. We screened a Saccharomyces cerevisiae deletion library to identify presumptive pyocy...
متن کاملStandardized chemical synthesis of Pseudomonas aeruginosa pyocyanin
Preparation of the toxin pyocyanin from the bacterium Pseudomonas aeruginosa is an exacting procedure. Pyocyanin is expensive to commercially purchase. The sellers do not give out the extraction procedure. Classically, pyocyanin preparation involves complicated multi-step P. aeruginosa culturing and solvent transfer extractions. The chemical synthesis first used (1979) has not been adequately d...
متن کاملIdentification of Pseudomonas aeruginosa by pyocyanin production on Tech agar.
Pseudomonas aeruginosa is the only gram-negative bacillus capable of producing the very distinctive water-soluble pigment pyocyanin. We evaluated the reliability of this characteristic as a unique test for the identification of this organism by using Tech agar (BBL Microbiology Systems, Cockeysville, Md.) medium. A retrospective and prospective analysis was performed with a total of 835 strains...
متن کاملPyocyanin production by Pseudomonas aeruginosa confers resistance to ionic silver.
Silver in its ionic form (Ag+), but not the bulk metal (Ag0), is toxic to microbial life forms and has been used for many years in the treatment of wound infections. The prevalence of bacterial resistance to silver is considered low due to the nonspecific nature of its toxicity. However, the recent increased use of silver as an antimicrobial agent for medical, consumer, and industrial products ...
