Query: NC_009445:6621996 Bradyrhizobium sp. ORS 278 chromosome, complete genome

Lineage: Bradyrhizobium; Bradyrhizobium; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: This strain was isolated from an Aeschynomene stem nodule and is photosynthetic, which is a rare trait in Rhizobium bacteria. These strains exhibit a photoheterotrophic and strictly aerobic photosynthesis. In culture, most stem isolates show the same pink coloration, while a few strains produce orange pigmentation. Pigment analyses showed that bacteriochlorophyll and spirilloxanthin, two pigments of the light harvesting system, are common to all of these photosynthetic Bradyrhizobium strains, whereas orange strains produce an additional bicyclic carotenoid, canthaxanthin (4,4'-diketo-beta-carotene). Bradyrhizobium sp. strain ORS278 produces the highest quantity of canthaxanthin of all tested photosynthetic bacteria; canthaxanthin represents 85% of its total carotenoid content.

Subject: NC_005955:1284500 Bartonella quintana str. Toulouse, complete genome

Lineage: Bartonella quintana; Bartonella; Bartonellaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: Bartonella quintana str. Toulouse was isolated from human blood in Toulouse, France in 1993. Causative agent of trench fever. This group of alpha proteobacteria are unique among pathogens in that they cause angiogenic lesions. This organism was first identified as the causative agent of louse-born trench fever during World War I. Up to 800 000 were infected in the trenches because of the louse insect vector that was widespread due to poor sanitation. The disease is now found associated with immunocompromized patients, especially HIV patients and homeless alcoholics.
