|Etymology:||Genus name: false unit
Species epithet: refers to the fluorescence of the colonies under UV-light.
|Significance:||[Of minor importance]|
|Type Strain:||ATCC 13525 = CCUG 1253 = NCTC 10038.|
|Gram +/Gram -:||G-|
|Metabolism:||Aerobic, but some strains are facultatively aerobic as they can utilize nitrate instead of oxygen, as a final electron acceptor in the respiratory chain.|
|Spec. Char.:||Optimal growth temperature is 25-30°C.|
|Hosts:||Fish and immunocompromised humans.|
|Reservoir:||Is an environmental bacterium that can be found in soil and water.|
|Disease:||Fin rot in especialla aquaria and aqua culture. Fin rot can also be caused by a fungal infection.|
|Clinical Picture:||The fins of the fish turn brownish black and break apart. Then the fin base becomes inflamed and the whole fin may fall off.|
|Virulence Factors:||If the concentration of iron is low in the environment, a green fluorescent pigment, pyoverdine, is produced. Pyoverdine is a so-called siderophore.|
|16S rRNA Seq.:|
|Comment:||A strain of P. fluorescence (Pf-CL145A) has been used to control invasive mussel species.
Milk contaminated by P. fluorescence becomes undrinkable.
