Query: NC_008043:86470 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.

Lineage: Stenotrophomonas maltophilia; Stenotrophomonas; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria
General Information: Environment: Rhizosphere, Host, Rhizosphere-colonizing; Temp: Mesophile. This species is an uncommon but serious source of infection in patients with breathing tubes such as endotracheal or tracheostomy tubes, or with chronically indwelling urinary catheters. Although the organism can colonize the devices without causing an infection, under certain conditions it can cause pneumonia, urinary tract infections, or an infection of the blood. This organism can also cause infection in immunocompromised patients. It has resistance to many commonly used antibiotics and therefore is often difficult to eradicate. Most strains are resistant to co-trimoxazole.
