Query: NC_013416:1588369 Aggregatibacter actinomycetemcomitans D11S-1, complete genome
Lineage: Aggregatibacter actinomycetemcomitans; Aggregatibacter; Pasteurellaceae; Pasteurellales; Proteobacteria; Bacteria
General Information: Aggregatibacter actinomycetemcomitans D11S-1 was recovered from a subject with aggressive periodontitis. Aggregatibacter actinomycetemcomitans, previously Actinobacillus actinomycetemcomitans typically resides in the oral cavity of humans and animals and can cause a number of diseases. The bacterium, along with 3 other organisms, is the main culprit in periodontis, which results in devastation to the bone supporting the teeth. Adherence to oral surfaces is controlled through the tad (tight adherence) locus, which may express proteins that are involved in type IV secretion.
Subject: NC_008309:555680 Haemophilus somnus 129PT, complete genome
Lineage: Histophilus somni; Histophilus; Pasteurellaceae; Pasteurellales; Proteobacteria; Bacteria
General Information: This strain is an asymptomatic carrier strain that was serum-resistant. Causes disease in cattle. 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.
