Query: NC_009655:866281 Actinobacillus succinogenes 130Z chromosome, complete genome
Lineage: Actinobacillus succinogenes; Actinobacillus; Pasteurellaceae; Pasteurellales; Proteobacteria; Bacteria
General Information: Succinate-producing bacterium. Originally isolated from bovine rumen, this species is one of the most promising succinate producers known. It can utilize a variety of sugars and produce a very high volume of succinate, which is used by the pharmaceutical industry. This organism has been improved over time by growth on fermentable carbon and sodium monofluoroacetate and selection of fluoroacetate-resistant mutants which have a higher succinate yield. The succinate yield has also been improved via a metabolic engineering approach, by cloning and overproducing the PEP-carboxykinase gene which catalyzes the addition of carbon dioxide to PEP to form oxalacetate and can work physiologically in both directions
Subject: NC_011149:2110861 Salmonella enterica subsp. enterica serovar Agona str. SL483,
Lineage: Salmonella enterica; Salmonella; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Salmonella enterica subsp. enterica serovar Agona causes gastroenteritis in humans and is also pathogenic to swine and other food animals. This serovar is able to contain the Salmonella genomic island 1 multidrug resistance gene cluster. 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.
