Siderophore-mediated cooperation and virulence in Pseudomonas aeruginosa.
Why should organisms cooperate with each other? Helping close relatives that are likely to share the same genes (kin selection) is one important explanation that is likely to apply across taxa. The production of metabolically costly extracellular iron-scavenging molecules (siderophores) by microorganisms is a cooperative behaviour because it benefits nearby conspecifics. We review experiments f...
متن کاملManuka honey inhibits siderophore production in Pseudomonas aeruginosa.
AIMS The aim of this study was to determine whether manuka honey affected siderophore production by three strains of Pseudomonas aeruginosa. METHODS AND RESULTS The minimum inhibitory concentration (MIC) of manuka honey against each of the test bacteria was determined. The effect of manuka honey on siderophore production by three strains of Ps. aeruginosa was investigated using the Chrome azu...
متن کاملType IV pili mechanochemically regulate virulence factors in Pseudomonas aeruginosa.
Bacteria have evolved a wide range of sensing systems to appropriately respond to environmental signals. Here we demonstrate that the opportunistic pathogen Pseudomonas aeruginosa detects contact with surfaces on short timescales using the mechanical activity of its type IV pili, a major surface adhesin. This signal transduction mechanism requires attachment of type IV pili to a solid surface, ...
متن کاملPseudomonas aeruginosa induces MUC5AC production via epidermal growth factor receptor.
Hypersecretory disease associated with Pseudomonas aeruginosa (PA) infections is characterised by increased goblet cells and increased mucin production. Recently, an epidermal growth factor receptor (EGFR) signalling cascade was shown to be a common pathway through which many stimuli induce mucin MUC5AC expression in airways by differentiation to a goblet cell phenotype. This study looked at wh...
متن کاملSiderophore-mediated signaling regulates virulence factor production in Pseudomonasaeruginosa.
Numerous bacteria secrete low molecular weight compounds termed siderophores that have a high affinity for iron ions. Siderophores have a well-documented role as iron-scavenging chemicals, chelating iron ions in the environment whereupon the ferrisiderophores reenter the bacterial cells by means of specific cell-surface receptors. The iron is then released for incorporation into bacterial prote...
