Query: NC_021172:3786725 Hyphomicrobium denitrificans 1NES1, complete genome
Lineage: Hyphomicrobium denitrificans; Hyphomicrobium; Hyphomicrobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Hyphomicrobium denitrificans has a biphasic life style, which consists of a motile phase of flagellated swarmer cells, and a cessile phase in which a long prosthecate is produced at one end of the bacteria through which budding cells emerge. Newly budded cells in turn produce flagella and go through a motile phase and the cycle continues. These organisms can colonize the surfaces of marine environments which enables additional species to colonize at later stages. This organism is also able to utilize methanol as a sole source of energy.
Subject: NC_004917:946550 Helicobacter hepaticus ATCC 51449, complete genome
Lineage: Helicobacter hepaticus; Helicobacter; Helicobacteraceae; Campylobacterales; Proteobacteria; Bacteria
General Information: This organism was found to be linked to an increasing incidence of liver tumors in mouse colonies at the National Cancer Institute in 1992. Normally it resides in the lower intestines, but it can cause chronic hepatitis. This organism has a similar urease gene cluster and cytolethal distending toxin as compared to Helicobacter pylori, but lacks other virulence factors such as the vacuolating cytotoxin and the cag pathogenicity island. However, it does contain a pathogenicity island that encodes proteins similar to those found in a type IV secretion system. Causes liver disease. This genus consists of organisms that colonize the mucosal layer of the gastrointestinal tract or are found enterohepatically (in the liver). This species was associated with an increase in liver tumors. It can cause active chronic hepatitis and typhlitis (inflammation of a region at the beginning of the large intestine), hepatocellular tumors, and gastric bowel disease in various mice strains.
