Query: NC_016931:269537 Rickettsia massiliae str. AZT80 chromosome, complete genome

Lineage: Rickettsia massiliae; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria

General Information: Members of this genus, like other Rickettsial organisms such as Neorickettsia and Anaplasma, are obligate intracellular pathogens. In both groups, the bacteria are transmitted via an insect, usually a tick, to a host organism where they target endothelial cells and sometimes macrophages. They attach via an adhesin, rickettsial outer membrane protein A, and are internalized where they persist as cytoplasmically free organisms. This bacterium is a member of the spotted fever group of the Rickettsiales and has been isolated from ticks in Europe and Africa. Rickettsia massiliae does not appear to cause disease in humans.

Subject: NC_010544:850502 Candidatus Phytoplasma australiense, complete genome

Lineage: Phytoplasma australiense; Phytoplasma; Acholeplasmataceae; Acholeplasmatales; Tenericutes; Bacteria

General Information: Phytoplasmas inhabit phloem (food-conducting vascular tissue) sieve elements of plants where they cause a variety of diseases. Transmission between plants is via insects that feed on the phloem. Candidatus Phytoplasma australiense was identified in diseased Chardonnay grapevines from South Australia. Symptoms include a yellowing of the leaves and reduced leaf size, which leads to reduced plant size and lower yields.
