Query: NC_017044:702483 Rickettsia parkeri str. Portsmouth chromosome, complete genome

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

General Information: Animal pathogen in Mammalia (intracellular obligate). Rickettsiae are obligate intracellular Gram-negative bacteria mostly found in arthropods, some of which cause mild to severe diseases in humans. Rickettsia parkeri, a member of the spotted fever group Rickettsia (SFGR), was first isolated from the Gulf Coast tick, Amblyomma maculatum, in 1937. In 2004, the first confirmed human infection with R. parkeri was reported in a 40-year-old man from the Tidewater area of coastal Virginia. The agent was isolated in cell culture from an eschar biopsy specimen and designated the Portsmouth strain; recently, the first recognized case of tick bite-associated human infection was described.

Subject: NC_018606:40000 Cardinium endosymbiont cPer1 of Encarsia pergandiella plasmid

Lineage: Cardinium endosymbiont of Encarsia pergandiella; Cardinium; Amoebophilaceae; Cytophagales; Bacteroidetes; Bacteria

General Information: This bacterium is often located within the reproductive tissues of the host. It is often found with other arthropod-associated Bacteroidetes that alter host biology (ex. Wolbachia). Distantly related hosts can harbor closely related Cardinium. Closely related Cardinium also tend to cluster with closely related hosts. Current research has shown 'Cardinium' to be an endosymbiot capable of altering host sexuality, resultant offspring as well as possible antibiotic resistance.
