Query: NC_002162:333303 Ureaplasma parvum serovar 3 str. ATCC 700970, complete genome
Lineage: Ureaplasma parvum; Ureaplasma; Mycoplasmataceae; Mycoplasmatales; Tenericutes; Bacteria
General Information: This organism (Ureaplasma urealyticum biovar 1) is normally found as a commensal organism in the human genital tract. As an opportunistic pathogen, it can cause a sexually-transmitted disease and is recognized as causing non-chlamydial non-gonococcal urethritis. It can also cause obstetric complications in pregnant women, severe infections in infants, as well as meningitis. Like other Mollicutes, it is a wall-less bacterium and has undergone marked genome reduction. This organism appears to generate ATP through the hydrolysis of urea by the urease enzyme.
Subject: NC_011883:1478173 Desulfovibrio desulfuricans subsp. desulfuricans str. ATCC 27774,
Lineage: Desulfovibrio desulfuricans; Desulfovibrio; Desulfovibrionaceae; Desulfovibrionales; Proteobacteria; Bacteria
General Information: Desulfovibrio desulfuricans subsp. desulfuricans str. ATCC 27774 was isolated from the rumen of a sheep. D. desulfuricans reduces sulfate to sulfide found in soil, freshwater, saltwater and the intestinal tract of animals. This organism grows anaerobically and utilizes a wide variety of electron acceptors, including sulfate, sulfur, nitrate, and nitrite, as well as others. The nitrate reduction pathway is not expressed while sulfate is available. Alternatively, the sulfate reduction pathway is constitutively expressed when the cells are growing with nitrate reduction. A number of toxic metals are reduced, including uranium (VI), chromium (VI) and iron (III), making this organism of interest as bioremediator. Metal corrosion, a problem that is partly the result of the collective activity of this bacterium, results in billions of dollars in losses each year to the petroleum industry. This organism is responsible for the production of poisonous hydrogen sulfide gas in marine sediments and in terrestrial environments such as drilling sites for petroleum products.
