Query: NC_008043:167108 Silicibacter sp. TM1040 mega plasmid, complete sequence

Lineage: Ruegeria; Ruegeria; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria

General Information: This strain was isolated from a culture of the dinoflagellate Pfiesteria piscicida CCMP1830 which has been implicated in many large scale algal blooms resulting in increased mortality in fish. The bacteria are attached to the surface of the dinoflagellate and in some ways allow the dinoflagellate to grow as those lacking the bacteria die off. The bacterium also chemotaxes towards the dinoflagellate product DMSP (dimethylsulfoniopropionate) and metabolizes it. DMSP is a major source of sulfur in marine ecosystems and plays a role in the sulfur biogeochemical cycle. The implication is a tight association between these important dinoflagellates and this marine bacterium.

Subject: NC_009348:2362163 Aeromonas salmonicida subsp. salmonicida A449, complete genome

Lineage: Aeromonas salmonicida; Aeromonas; Aeromonadaceae; Aeromonadales; Proteobacteria; Bacteria

General Information: Aeromonas salmonicida subsp. salmonicida A449 was isolated from a brown trout with furunculosis. The agent of furunculosis, a major cause of mortality among salmonid fishes. This bacterium is the causal agent of furunculosis. Although it was discovered nearly 100 years ago, it is not known how the diesase is spread. Furunculosis is temperature sensistive, with acute cases occurring when the water is above 20 degrees C and chronic cases developing at temperatures below 13 degrees C. The acute form of the disease causes the fish to turn a dark color and stop eating.
