Query: NC_013716:1756545 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.
Subject: NC_010337:1188373 Heliobacterium modesticaldum Ice1, complete genome
Lineage: Heliobacterium modesticaldum; Heliobacterium; Heliobacteriaceae; Clostridiales; Firmicutes; Bacteria
General Information: Heliobacterium modesticaldum strain Ice1, the type strain of this species, was isolated from Icelandic hot spring volcanic soils. It grows optimally above 50 degrees Celsius, grows best photoheterotrophically, but can grow in the dark chemotrophically on pyruvate. Phototrophic thermophile. This organism is an anoxygenic phototroph isolated from hot spring microbial mats and volcanic soil. Cell wall structure, the ability to form endospores, and 16S ribosomal RNA analysis place Heliobacterium modesticaldum in a family of phototrophic bacteria related to the Clostridia. Heliobacterium modesticaldum is able to fix nitrogen and may contribute significantly to the nitrogen availability in microbial mats.
