Query: NC_009900:1011000 Rickettsia massiliae MTU5, complete genome
Lineage: Rickettsia massiliae; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: Rickettsia massiliae MTU5 was isolated from the tick Rhipicephalus turanicus collected from horses in Le Sambuc, Bouches-du Rhone, France. Members of this genus, like other Rickettsial organisms such as Neorickettsia and Anaplasma, are obligate intracellular pathogens. In both groups, the bacteria are transmitted via an insect, usually a tick, to a host organism where they target endothelial cells and sometimes macrophages. They attach via an adhesin, rickettsial outer membrane protein A, and are internalized where they persist as cytoplasmically free organisms. Rickettsia massiliae is a member of the spotted fever group of the Rickettsiales and has been isolated from ticks in Europe and Africa. Rickettsia massiliae does not appear to cause disease in humans.
Subject: NC_006833:838330 Wolbachia endosymbiont strain TRS of Brugia malayi, complete
Lineage: Wolbachia endosymbiont of Brugia malayi; Wolbachia; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria
General Information: A nematode endosymbiont. This group of bacteria are associated with a variety of invertebrate species, some as pathogens, some in a symbiotic 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. This strain naturally infects Brugia malayi, a parasitic filarial nematode that causes lymphatic filariasis, one of the most devastating diseases in humans. The endosymbiont plays important roles in the biology of the nematide host. One of the known such effects are aberrant sex ratios in the host, parthenogenesis and feminization of genetic males, etc.
