Query: NC_007940:1138324 Rickettsia bellii RML369-C, complete genome
Lineage: Rickettsia bellii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This strain (RML 369-C) was isolated in embryonated chicken eggs from a triturated (powdered) pool of unfed adult Dermacentor variabilis ticks collected from vegetation near Fayetteville, Arkansas, USA, in 1966. Transmitted via American ticks. This organism represents the third group of Rickettsial species and is separate from the spotted fever group and the typhus group. This organism is transovarially transmitted in American ticks and shows the largest range of host organisms including Dermacentor and Amblyomma.
Subject: NC_010424:1563033 Candidatus Desulforudis audaxviator MP104C, complete genome
Lineage: Desulforudis audaxviator; Desulforudis; Peptococcaceae; Clostridiales; Firmicutes; Bacteria
General Information: Its genome indicates a motile, sporulating, sulfate-reducing, chemoautotrophic thermophile that can fix its own nitrogen and carbon by using machinery shared with archaea. Candidatus Desulforudis audaxviator is a gram positive sulfate reducing bacteria identified in fracture water from a borehole at a depth of 2.8 km in a South African gold mine. Water from these boreholes is very old (low-biodiversity fracture water), suggesting that these bacteria have been isolated from the Earth's surface for as much as several million years.
