Query: NC_006958:828089 Corynebacterium glutamicum ATCC 13032, complete genome
Lineage: Corynebacterium glutamicum; Corynebacterium; Corynebacteriaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: Causes bovine brucellosis. 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. 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.
Subject: NC_010161:1844452 Bartonella tribocorum CIP 105476, complete genome
Lineage: Bartonella tribocorum; Bartonella; Bartonellaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This organism was isolated from the blood of wild rats and from fleas obtained from wild rats. Transmission of these organisms is often through an insect vector. Once in a host, this intracellular pathogen is internalized by an actin-dependent mechanism, and primarily targets endothelial cells, although other cells can be infected. The proliferation of the vascular endothelium (bacillary angiomatosis) is characterisitic of Bartonella infection and results in multiplication of the bacterium's host cells. Infected macrophages are stimulated to release vascular endothelial growth factor (VEGF) and interleukin 1 beta, both of which promote angiogenesis. Endothelial cells are also stimulated to grow and divide by direct contact with bacterial cells. In addition, programmed cell death (apoptosis) of endothelial cells is inhibited, combatting a common mechanism eukaryotic cells use to deal with bacterial infection. Other pathogenicity factors include pili and outer membrane adhesins for attachment to host cells. This organism is genetically related to Bartonella elizabethae which was isolated from a case of endocarditis in a human.
