Query: NC_013119:511500 Brucella microti CCM 4915 chromosome 1, complete sequence
Lineage: Brucella microti; Brucella; Brucellaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Brucella microti was isolated in 2000 from systemically infected voles in South Moravia, Czech Republic and has been more recently isolated from foxes and apparently free-living in soil in Czech soil. The organism is characterized by rapid growth on standard media and high metabolic activity, which is atypical for Brucella.
Subject: NC_012416:852000 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.
