Query: NC_014836:497350 Desulfurispirillum indicum S5 chromosome, complete genome
Lineage: Desulfurispirillum indicum; Desulfurispirillum; Chrysiogenaceae; Chrysiogenales; Chrysiogenetes; Bacteria
General Information: Environment: Fresh water; Temp: Mesophile. This is the first cultured species of the proposed new genus "Desulfurispirillum", and the sequencing of its genome will expand the range of experimental approaches that researchers can use to characterize its metabolic pathways for energy production and understand how these pathways are regulated. This organism is notable for its ability to reduce selenate to selenite and further to insoluble elemental selenium, in a process called dissimilatory selenate reduction.
Subject: NC_003454:249304 Fusobacterium nucleatum subsp. nucleatum ATCC 25586, complete
Lineage: Fusobacterium nucleatum; Fusobacterium; Fusobacteriaceae; Fusobacteriales; Fusobacteria; Bacteria
General Information: Normal oral and gastrointestinal bacterium. This genus contains mostly obligately anaerobic bacilli. Many of the isolates are spindle-shaped, or fusiform. This organism belongs to the normal microflora of the human oral and gastrointestinal tracts. It is a very long and slender spindle-shaped bacillus with sharply pointed ends that is characterized by the ability to invade soft tissues. It acts as a bridge between early and late colonizers of the tooth surface, and exerts synergism with other bacteria in mixed infections. It is most frequently associated with periodontal diseases, as well as with some invasive human infections of the head and neck, chest, lung, liver and abdomen, and some anginas. One of the major amino acid and sugar fermentation pathways in Fusobacterium nucleatum produces butyric and acetic acids.
