Query: NC_008309:1851189 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.

General Information: These cyanobacteria are bluegreen algae that are capable of fixing carbon and nitrogen. They form long filaments and can be found worldwide in various aquatic environments as well as some terrestrial ones. These bacteria can form a variety of differentiated cell types, including spore-like cells (akinetes), small motile filaments (hormongia) and most importantly, heterocysts that are nitrogen-producing cells. The heterocyst produces multiple layers outside of its cell wall, shuts down photosystem II in order to inhibit oxygenic photosynthesis and ramps up metabolism in order to use up the oxygen present. Heterocysts donate fixed nitrogen compounds as amino acids to neighboring cells and in return receive a photosynthetically produced carbon source such as sucrose. These organisms produce toxic blooms in aquatic environments that are harmful or fatal to animals and humans due to the various cyanotoxins they produce. Anabaena variabilis is a filamentous heterocyst-forming cyanobacterium that fixes nitrogen and CO2 using the energy of sunlight via oxygen-evolving plant-type photosynthesis. In addition, this organism has been studied extensively for the production of hydrogen using solar energy.
