Query: NC_012730:293634 Rickettsia peacockii str. Rustic, complete genome
Lineage: Rickettsia peacockii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: Rickettsia peacockii was initially identified in wood ticks from the eastern side of the Bitterroot Valley in Montana. Cases of Rocky Mountain spotted fever in the Bitterroot Valley are associated with exposure to ticks from the western side. Ticks from the east side are primarily infected with R. peacockii which is nonvirulent and may prevent the establishment of pathogenic Rickettsia species in these ticks.
Subject: NC_010337:565730 Heliobacterium modesticaldum Ice1, complete genome
Lineage: Heliobacterium modesticaldum; Heliobacterium; Heliobacteriaceae; Clostridiales; Firmicutes; Bacteria
General Information: Heliobacterium modesticaldum strain Ice1, the type strain of this species, was isolated from Icelandic hot spring volcanic soils. It grows optimally above 50 degrees Celsius, grows best photoheterotrophically, but can grow in the dark chemotrophically on pyruvate. Phototrophic thermophile. This organism is an anoxygenic phototroph isolated from hot spring microbial mats and volcanic soil. Cell wall structure, the ability to form endospores, and 16S ribosomal RNA analysis place Heliobacterium modesticaldum in a family of phototrophic bacteria related to the Clostridia. Heliobacterium modesticaldum is able to fix nitrogen and may contribute significantly to the nitrogen availability in microbial mats.
