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_008601:1733940 Francisella tularensis subsp. novicida U112, complete genome

Lineage: Francisella tularensis; Francisella; Francisellaceae; Thiotrichales; Proteobacteria; Bacteria

General Information: Avirulent species. Francisella novicida is closely related to Francisella tularensis, the causative agent for tularemia but is nonvirulent. This organism, however may cause disease in immunocompromised individuals. They do however cause a disease in mice that is very similar to tularemia. This strain was isolated from water in Utah, USA in 1950. Francisella tularensis is a non-motile, aerobic, rod-shaped Gram-negative bacterium and is the causative agent of tularemia.
