Rickettsia massiliae MTU5

Names Rickettsia massiliae MTU5
Accession numbers NC_009897, NC_009900
Background Rickettsia massiliae was first isolated in 1992 from the Rhipicephalus sanguineus tick collected in Marseille, France. Since then, it has been commonly detected in Rhipicephalus ticks from Central Africa, France, Greece, Mali, Portugal, Spain, Switzerland and the United States. It has also been recently identified in Ixodes ricinus ticks. R. massiliae is transmitted transovarially, at least in Rhipicephalus turanicus. Rickettsia massiliae (strain Mtu5) has been isolated from the R. turanicus tick collected on horses in Camargue, France. In 1985, in Palermo, Italy, it was isolated from a patient hospitalized for fever and a rash, however only in 2005 was it identified as Rickettsia massiliae. The chromosome of Rickettsia massiliae (strain Mtu5) exhibits a high level of colinearity with Rickettsia conorii except for a fragment of 54.6 kb which is absent in R. conorii. This region contains 44 genes including 14 tra-releated genes. This tra cluster seems to have been acquired by a recent R. massiliae ancestor by horizontal transfer from another Rickettsia species closely related to R. bellii. (EBI Integr8)
