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_005295:647275 Ehrlichia ruminantium str. Welgevonden, complete genome

Lineage: Ehrlichia ruminantium; Ehrlichia; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria

General Information: This strain was isolated in mice from an infected tick. Obligate intracellular bacterium and causative agent of heartwater. This organism causes heartwater, a disease with a high mortality rate that affects both wild and domesticated ruminants in sub-Saharan Africa and parts of the Caribbean. The name heartwater refers to the hydropericardium (excessive fluid in the sac surrounding the heart) commonly found associated with infection. This organism is found in membrane-bound vacuoles in endothelial cells and neutrophils and is an obligate intracellular parasite.
