Query: NC_010519:1963256 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_003384:157158 Salmonella enterica subsp. enterica serovar Typhi str. CT18 plasmid
Lineage: Salmonella enterica; Salmonella; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This strain is a multidrug resistant strain of Salmonella typhi. This serovar is a human-specific organism that causes the life-threatening illness Typhoid fever which is acquired by coming into contact with contaminated food or water. Causes enteric infections. This group of Enterobactericiae have pathogenic characteristics and are one of the most common causes of enteric infections (food poisoning) worldwide. They were named after the scientist Dr. Daniel Salmon who isolated the first organism, Salmonella choleraesuis, from the intestine of a pig. The presence of several pathogenicity islands (PAIs) that encode various virulence factors allows Salmonella spp. to colonize and infect host organisms. There are two important PAIs, Salmonella pathogenicity island 1 and 2 (SPI-1 and SPI-2) that encode two different type III secretion systems for the delivery of effector molecules into the host cell that result in internalization of the bacteria which then leads to systemic spread.
