Query: NC_002978:918000 Wolbachia endosymbiont of Drosophila melanogaster, complete genome
Lineage: Wolbachia endosymbiont of Drosophila melanogaster; Wolbachia; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria
General Information: Wolbachia endosymbiont of Drosophila melanogaster. Fruitfly endosymbiont. This group of bacteria are associated with a variety of invertebrate species, some as pathogens, some in a symbiotic or other type of relationship. Typically these organisms are transmitted maternally from mother to daughter transovarially (through the egg) although these bacteria can affect their hosts reproductive capabilities in order to enhance transmission. The net outcome is the increase of hosts carrying the bacteria in the next generation, thereby increasing transmission. Wolbachia endosymbiont of Drosophila melanogaster is an obligate intracellular endosymbiont of the fruit fly Drosophila melanogaster.
Subject: NC_021182:2013500 Clostridium pasteurianum BC1, complete genome
Lineage: Clostridium pasteurianum; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria
General Information: Environment: Soil; Isolation: Coal-cleaning residues; Temp: Mesophile; Temp: 30C. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive clostridia-like ancestors with a low GC content in DNA. Known opportunistic toxin-producing pathogens in animals and humans. Some species are capable of producing organic solvents (acetone, ethanol, etc,), molecular hydrogen and other useful compounds. Clostridium pasteurianum was first isolated from soil by the Russian microbiologist Sergey Winogradsky. This organism is able to fix nitrogen and oxidize hydrogen into protons. The genes involved in nitrogen fixation and hydrogen oxidation have been extensively studied in this organism.
