Query: NC_009342:2528426 Corynebacterium glutamicum R chromosome, complete genome
Lineage: Corynebacterium glutamicum; Corynebacterium; Corynebacteriaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: This strain was isolated from meadow soil in Japan. Soil bacterium with industrial uses. They may be found as members of the normal microflora of humans, where these bacteria find a suitable niche in virtually every anatomic site. This organism is a well-studied soil bacterium of considerable importance in biotechnology, in particular for the fermentative production of L-amino acids for food and fodder industry. The name was originaly given for this species for its ability to produce significant quantities (>100 g per liter) of glutamic acid (glutamate), an important food enhancer that has a meaty taste and flavor. C. glutamicum is currently used commercially to produce glutamate and other amino acids (L-lysine) and compounds. The first strain of the species was isolated in 1957 by S. Kinoshita and colleagues while searching for an efficient glutamate-producer.

Lineage: Shigella sonnei; Shigella; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This strain is an isolate from an epidemic in China in the 1950s. A leading cause of dysentery. This genus is named for the Japanese scientist (Shiga) who first discovered these organisms in the 1890s. They are closely related to the Escherichia group, and may be considered the same species. These organisms are human-specific pathogens that are transmitted via contaminated food and water and are the leading causes of endemic bacillary dysentery, causing over 160 million cases of infection and 1 million deaths yearly worldwide. The bacteria infect the epithelial lining of the colon, causing acute inflammation by entering the host cell cytoplasm and spreading intercellularly. This extremely virulent organisms that can cause an active infection after a very low exposure. Both the type III secretion system, which delivers effector molecules into the host cell, and some of the translocated effectors such as the invasion plasmid antigens (Ipas), are encoded on the plasmid. The bacterium produces a surface protein that localizes to one pole of the cell (IcsA) which binds to and promotes actin polymerization, resulting in movement of the bacterium through the cell cytoplasm, and eventually to neighboring cells, which results in inflammatory destruction of the mucosal lining. This organism is the leading cause of dysentery in industrialized countries. The disease is usually less severe than other types of Shigella, causing mild diarrhea and dehydration.
