|---|---|---|---|---|---|---|---|---|---|
| Category: | Causes hemolysis | ||||||||
| Etymology: | Genus name: false unit Species epithet: refers to the fluorescence of the colonies under UV-light. | ||||||||
| Significance: | [Of minor importance] | ||||||||
| Taxonomy: | Class Gammaproteobacteria Order Pseudomonadales Family Pseudomonadaceae Genus Pseudomonas |
||||||||
| Type Strain: | ATCC 13525 = CCUG 1253 = NCTC 10038. | ||||||||
| Macromorphology (smell): | |||||||||
| Micromorphology: | Rod shaped | ||||||||
| 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. | ||||||||
| Catalase/Oxidase: | ?/+ | ||||||||
| Spec. Char.: | Optimal growth temperature is 25-30°C. | ||||||||
| 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. |
||||||||
| Hosts: | Fish and immunocompromised humans. | ||||||||
| 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. | ||||||||

| Comment: | A strain of P. fluorescence (Pf-CL145A) has been used to control invasive mussel species.
Milk contaminated by P. fluorescence becomes undrinkable. | ||||||||
