Caption: Pseudomonas spp. - Gram-negative, aerobic, enteric, rod prokaryote with polar flagella. The bacterial genus Pseudomonas (a pseudomonad) includes plant pathogenic bacteria such as P. syringae, the human pathogen P. aeruginosa, the ubiquitous soil bacterium P. putida, and some species that are known to cause problems in dairy products. P. aeruginosa usually causes problems to humans who have already have had their immune systems weakened. This complicated, resistant bacteria causes skin infections, urinary tract infections and septicemia. One in ten hospital acquired infections is from Pseudomonas. Cystic fibrosis patients are also predisposed to P. aeruginosa infection of the lungs. Their resistance to most antibiotics is attributed to their rapid efflux pumps that pump out the antibiotics before they are able to work. Most species produce a slime layer that cannot be phagocytosed, and which aids in the production of surface-colonizing biofilms. P. fluorescens colonizes is easily recognized as it secretes large amounts of fluorescent, yellow-green siderophores under iron-limited conditions. P. aeruginosa is an opportunistic animal pathogen that secretes bright blue-green siderophores called pyocyanin. Members of the genus Pseudomonas have been used as biocontrol agents.
