Query: NC_006832:252952 Ehrlichia ruminantium str. Welgevonden, complete genome
Lineage: Ehrlichia ruminantium; Ehrlichia; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This strain was obtained from an infected tick and maintained by serial infection in mice. 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.
Subject: NC_005303:272915 Onion yellows phytoplasma OY-M, complete genome
Lineage: Onion yellows phytoplasma; Phytoplasma; Acholeplasmataceae; Acholeplasmatales; Tenericutes; Bacteria
General Information: This strain (OY-M) is derived from a wild-type disease-causing strain (OY-W; onions yellow disease) which was isolated in Saga Prefecture, Japan, in 1982, and shows mild symptoms and does not cause stunting nor phloem hyperplasia (excessive increase in number of cells). Plant pathogenic bacterium. Phytoplasmas inhabit phloem (food-conducting vascular tissue) sieve elements of plants where they cause a variety of diseases. There is great interest in sequencing these organisms since they are currently unculturable and examination of the genome may lead to methods to deal with the diseases they cause including the development of antimicrobial agents.
