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_007492:3462929 Pseudomonas fluorescens PfO-1, complete genome
Lineage: Pseudomonas fluorescens; Pseudomonas; Pseudomonadaceae; Pseudomonadales; Proteobacteria; Bacteria
General Information: This strain was isolated from agricultural loam (sand, clay, and organic matter) soil in 1988 by Compeau et al. and is well adapted to soil environments. Bacteria belonging to the Pseudomonas group are common inhabitants of soil and water and can also be found on the surfaces of plants and animals. Pseudomonas bacteria are found in nature in a biofilm or in planktonic form. Pseudomonas bacteria are renowned for their metabolic versatility as they can grow under a variety of growth conditions and do not need any organic growth factors. This organism is a nonpathogenic saprophyte which inhabits soil, water and plant surface environments. If iron is in low supply, it produces a soluble, greenish fluorescent pigment, which is how it was named. As these environmentally versatile bacteria possess the ability to degrade (at least partially) multiple different pollutants, they are studied in their use as bioremediants.
