Query: NC_012438:1600534 Sulfurihydrogenibium azorense Az-Fu1 chromosome, complete genome
Lineage: Sulfurihydrogenibium azorense; Sulfurihydrogenibium; Hydrogenothermaceae; Aquificales; Aquificae; Bacteria
General Information: This strain was isolated from a terrestrial hot spring in the Azores, where it was living at temperatures between 65 degrees C and 70 degrees C. Hydrogen-oxidizing thermophile. Sulfurihydrogenibium azorense is a thermophilic bacterium that is able to use hydrogen and sulfur compounds as electron donors. This organism is also able to use ferric iron and arsenate as electron acceptors. This is the first pure culture terrestrial member of the Aquificales group, isolated by dilution-to-extinction methods.
Subject: NC_012416:4973 Wolbachia sp. wRi, complete genome
Lineage: Wolbachia; Wolbachia; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria
General Information: Endosymbiont. Obligate intracellular bacterium infects around 20% of all insect species. Naturally infects Drosophila simulans and induces almost complete cytoplasmic incompatibility in its host. Wolbachia sp. subsp. Drosophila simulans (strain wRi) is an intracellular proteobacterium that infect insects as well as isopods, spiders, scorpions, mites, and filarial nematodes. It is maternally inherited and induces reproductive alterations of insect populations by male killing, feminization, parthenogenesis, or cytoplasmic incompatibility. In insect populations, Wolbachia sp. induce reproductive manipulations to enhance their own spreading. The most frequently observed reproductive abnormality is cytoplasmic incompatibility, where uninfected females are unable to produce offspring with infected males, whereas infected females can produce offspring with both infected and uninfected males, thus creating a reproductive advantage for infected females. Other spectacular effects of Wolbachia sp. infections are male embryo killing, feminization, and parthenogenesis induction.
