Query: NC_011985:61003 Agrobacterium radiobacter K84 chromosome 1, complete genome
Lineage: Agrobacterium tumefaciens; Agrobacterium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This strain has been developed for worldwide commercial use to control crown gall. This species is used commercially to control crown gall, a tumorogenic plant disease caused by the ubiquitous soil-borne pathogen Agrobacterium tumefaciens, which affects susceptible woody plants worldwide. The pathogen is responsible for nursery and orchard losses among stone fruit trees, grapes, apples, pears, nut trees, caneberries, clematis, hops, kiwifruit, persimmons, roses and many ornamental annuals, trees and shrubs. Infected plants are usually weakened and unproductive due to their damaged root system.
Subject: NC_005956:1572500 Bartonella henselae str. Houston-1, complete genome
Lineage: Bartonella henselae; Bartonella; Bartonellaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Bartonella henselae str. Houston-1 (ATCC 49882) was isolated from human blood in Houston Texas. Causative agent of cat scratch fever. This group of alpha proteobacteria are unique among pathogens in that they cause angiogenic lesions. This organism was identified as the causative agent of cat scratch fever, a disease found commonly in children or in immunocompromised adults. 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.
