Query: 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.

Subject: NC_012962:3864000 Photorhabdus asymbiotica, complete genome

Lineage: Photorhabdus asymbiotica; Photorhabdus; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: This strain is a North American clinical isolate from human blood. Photorhabdus asymbiota, formerly Xenorhabdus luminescens, has been isolated from human wound and blood infections often in association with spider bites. This species can also be isolated from the entomopathogenic nematode Heterorhabditis indica. Photorhabdus asymbiota is divided into two subspecies, subsp. australis which contains the Australian clinical isolates and subsp. asymbiota which contains the North American isolates. Photorhabdus is currently subdivided into three species, luminescens, temperate and asymbiotica all of which have been isolated as symbionts of heterorhabditid nematodes. This organism is unusual in that it is symbiotic within one insect, and pathogenic in another, the only organism that is known to exhibit this dual phenotype.
