Once pyoverdine is secreted, it diffuses freely in the environment. Iron-bound pyoverdine (also known as ferripyoverdine) can be taken up by any bacterial cell with the appropriate receptor, although this varies between strains. Importantly, this creates a common good which can be exploited by 'cheaters' … See more Pyoverdines (alternatively, and less commonly, spelled as pyoverdins) are fluorescent siderophores produced by certain pseudomonads. Pyoverdines are important virulence factors, and are required for See more Like most siderophores, pyoverdine is synthesized and secreted into the environment when the microorganism that produces it detects that intracellular iron concentrations … See more Biosynthesis In Pseudomonas aeruginosa PAO1 there are 14 pvd genes involved in the biosynthesis of pyoverdine. Pyoverdine … See more Currently, no widespread and systematic nomenclature is used to differentiate pyoverdine structures. A system was proposed in 1989, … See more Although many (>100) forms of pyoverdine have been isolated and studied, they all have certain characteristics in common. Each pyoverdine … See more Pyoverdine has been reported to be required for virulence in a variety of disease models, including C. elegans and various models of murine infection (e.g., burn models, pneumonia models, etc.). As noted above, pyoverdine contributes in several fashions to … See more • 1850s: Sédillot notes a blue-green discharge from surgical wound dressings. • 1860: Pyoverdine (although not so named) was extracted from … See more WebMar 30, 2010 · Some of these receptors are used to take up pyoverdines produced by other members of the genus as demonstrated for P. aeruginosa strains, the majority of which are able to take up type I ferripyoverdine via a conserved (and probably ancient) receptor, FpvB (Ghysels et al. 2004; Bodilis et al. 2009).
