Query: NC_020419:344000 Uncultured Termite group 1 bacterium phylotype Rs-D17 DNA, complete
Lineage: uncultured Termite group 1 bacterium; enviromental sample; ; ; Elusimicrobia; Bacteria
General Information: The Termite Group 1 (TG1) bacteria are a dominant group in termite guts, where they are part of the symbiotic microbial community that is required for the termite to thrive. The TG1 bacteria are found as intracellular symbionts of various cellulolytic protists.
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.
