Query: NC_011985:194973 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_008710:621822 Borrelia turicatae 91E135, complete genome
Lineage: Borrelia turicatae; Borrelia; Spirochaetaceae; Spirochaetales; Spirochaetes; Bacteria
General Information: This strain was isolated in the USA from the soft tick Ornithodoros turicatae. Borrelia turicatae is the causative agent of tick-borne relapsing fever in the southwestern USA. Ticks become infected with Borrelia while feeding on an infected mammal, usually a rodent or squirrel. Borrelia then multiplies rapidly, causing a generalized infection throughout the tick. While feeding, the tick passes the spirochete into a mammalian host through its infectious saliva. Relapsing fever is characterized by period of chills, fever, headache, and malaise, followed by an asymptomatic, followed by another episode of symptoms. The cycle of relapsing is due to changes in the surface proteins of Borrelia, which allow it to avoid detection and removal by the host immune system. This antigenic variation is the result of homologous recombination of silent proteins into an expressed locus, causing partial or complete replacement of one serotype with another. These plasmids carry genes involved in antigenic variation and pathogenicity.
