Query: NC_008044:1401814 Silicibacter sp. TM1040, complete genome

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_013716:5201097 Citrobacter rodentium ICC168, complete genome

Lineage: Citrobacter rodentium; Citrobacter; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: Citrobacter rodentium is the causative agent of transmissible murine colonic hyperplasia in mice. This disease is characterized by a hyperproliferation of the epithelial cells in the colon similar to that found in humans suffering from idiopathic inflammatory bowel disease. In addition this organism contains virulence factors similar to those found in enterohemorrhagic Escherichia coli and enteropathogenic E. coli. C. rodentium are being used as models for studying mucosal response to infection, colon tumor production, and virulence associated with pathogenic E. coli.
