Query: NC_002978:200878 Wolbachia endosymbiont of Drosophila melanogaster, complete genome Lineage: Wolbachia endosymbiont of Drosophila melanogaster; Wolbachia; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria General Information: Wolbachia endosymbiont of Drosophila melanogaster. Fruitfly endosymbiont. This group of bacteria are associated with a variety of invertebrate species, some as pathogens, some in a symbiotic or other type of relationship. Typically these organisms are transmitted maternally from mother to daughter transovarially (through the egg) although these bacteria can affect their hosts reproductive capabilities in order to enhance transmission. The net outcome is the increase of hosts carrying the bacteria in the next generation, thereby increasing transmission. Wolbachia endosymbiont of Drosophila melanogaster is an obligate intracellular endosymbiont of the fruit fly Drosophila melanogaster.

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.
