Query: NC_010519:275976 Haemophilus somnus 2336 chromosome, complete genome

Lineage: Histophilus somni; Histophilus; Pasteurellaceae; Pasteurellales; Proteobacteria; Bacteria

General Information: This strain was isolated from the lung of a calf which had pneumonia. A group of organisms that are either obligate parasites or commensal organisms found in animal mucous membranes. Almost all species require the presence of important growth factors found in the blood of their hosts, including either X factor (protoporphyrin IX or heme) or V factor (nicotinamide adenine dinucleotide (NAD or NADP)). This organism is a major cause of disease in feedlot cattle. It causes constriction of blood vessels supplying major organs, restricting blood supply which leads to reduced oxygen delivery, and leads to tissue damage and death. The diseases that result are pneumonia, arthritis, myocarditis (inflammation of heart muscle), and reproductive problems resulting in the loss of millions of dollars in animals each year.

Subject: NC_003228:2973266 Bacteroides fragilis NCTC 9343, complete genome

Lineage: Bacteroides fragilis; Bacteroides; Bacteroidaceae; Bacteroidales; Bacteroidetes; Bacteria

General Information: This organism can become an opportunistic pathogen, infecting anywhere in the body and causing abcess formation. Enterotoxigenic Bacterioides fragilis (ETBF) is associated with diarrheal diseases. Common gut bacterium. This group of microbes constitute the most abundant members of the intestinal microflora of mammals. Typically they are symbionts, but they can become opportunistic pathogens in the peritoneal (intra-abdominal) cavity. Breakdown of complex plant polysaccharides such as cellulose and hemicellulose and host-derived polysaccharides such as mucopolysaccharides is aided by the many enzymes these organisms produce. Although only a minor component of the human gut microflora, this organism is a major component of clinical specimens and is the most common anaerobe isolated.
