Query: NC_012633:276500 Rickettsia africae ESF-5, complete genome

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

General Information: This organism was isolated from a cattle tick, Amblyomma variegatum, collected in Ethiopia. This organism, a member of the spotted fever group of the Rickettsiales, is found in sub-Saharan Africa and the Caribbean. Rickettsia africae causes a flu-like illness, characterized by a mild fever and severe headache, without the skin rash common to other spotted fever group Rickettsia species. 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.

Subject: NC_014760:299392 Mycoplasma bovis PG45 chromosome, complete genome

Lineage: Mycoplasma bovis; Mycoplasma; Mycoplasmataceae; Mycoplasmatales; Tenericutes; Bacteria

General Information: This bacterium causes a contagious disease of cattle causing respiratory disease, mastitis, and arthritis. It is found worldwide and is inherently resistant to certain groups of antibiotics because it does not possess a cell wall. More recently, this species has become resistant to tetracycline, tilmicosin and spectinomycin which have been traditionally used in its control. The disease is spread between herds by the transfer of infected but seemingly healthy animals which shed viruses. It has also been introduced into healthy herds via frozen semen collected from an infected bull. The economic losses and negative impact on international trade from this disease have been considerable, and efforts are now underway to develop a vaccine.
