Query: NC_007205:424500 Candidatus Pelagibacter ubique HTCC1062, complete genome
Lineage: Pelagibacter ubique; Pelagibacter; Pelagibacteraceae; Rickettsiales; Proteobacteria; Bacteria
General Information: They were originally named SAR11 and known only from their rRNA genes, which were first identified in environmental samples from the Sargasso Sea in 1990. P. ubique are possibly the most numerous bacteria in the world.
Subject: NC_012778:2997 Eubacterium eligens ATCC 27750, complete genome
Lineage: Eubacterium eligens; Eubacterium; Eubacteriaceae; Clostridiales; Firmicutes; Bacteria
General Information: Eubacterium eligens ATCC 27750 is part of the normal human gut flora. This genus has been isolated as normal flora from feces, rumen, and periodontal tissue. Eubacterium spp. are thought to play a beneficial role in maintaining the normal ecology of the large intestine, in part by producing chemicals like butyric acid which act to inhibit the growth of other bacteria. These organisms are occasionally isolated from wounds and abscesses and may be an opportunistic pathogen. This genus has also been isolated from sewage and soil.
