Query: NC_004344:672550 Wigglesworthia glossinidia endosymbiont of Glossina brevipalpis,
Lineage: Wigglesworthia glossinidia; Wigglesworthia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This organism is the obligate endosymbiont for the tsetse fly Glossina brevipalpis. As Wigglesworthia brevipalpis resides intracellularly, the resulting co-evolution with its host over millions of years has led to a drastic reduction in the bacterium's genome size, resulting in this its inability to survive outside the host. Tsetse fly endosymbiont. This organism is the obligate endosymbiont for the tsetse fly Glossina brevipalpis, Glossina tachinoides, Glossina palpalis palpalis, and Glossina austeni. The tsetse fly is a vector for African trypanosomes, and is the main transmitter of deadly diseases in animals and humans in Africa. The fly feeds on a restricted diet, exclusively consisting of vertebrate blood, and lacks certain metabolic compounds needed for survival and reproduction. To complement this lack in nutrients, the tsetse fly relies mainly on the intracellular bacterial symbiont, Wigglesworthia glossinidia for its viability and fecundity.
Subject: NC_011883:2031222 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.
