Rickettsia conorii is a Gram-negative, obligate intracellular bacterium of the genus Rickettsia that causes human disease called Boutonneuse fever, Mediterranean spotted fever, Israeli tick typhus, Astrakhan spotted fever, Kenya tick typhus, Indian tick typhus, or other names that designate the locality of occurrence while having distinct clinical features.^[3]^[4] It is a member of the spotted fever group and the most geographically dispersed species in the group, recognized in most of the regions bordering on the Mediterranean Sea and Black Sea, Israel, Kenya, and other parts of North, Central, and South Africa, and India.^[3] The prevailing vector is the brown dog tick, Rhipicephalus sanguineus. The bacterium was isolated by Emile Brumpt in 1932^[5] and named after A. Conor who, in collaboration with A. Bruch, provided the first description of boutonneuse fever in Tunisia in 1910.^[6]

The genome of the bacterium has been sequenced^[7] and four subspecies have been identified.^[8]

Rickettsia monacensis as Cause of Mediterranean Spotted Fever-like Illness, Italy.

Madeddu G, Mancini F, Caddeo A, Ciervo A, Babudieri S, Maida I, Fiori ML, Rezza G, Mura MS.AbstractTO THE EDITOR: Rickettsia conorii, the etiologic agent of Mediterrenean spotted fever (MSF), is transmitted to humans by the brown dog tick (Rhipicephalus sanguineus). MSF is endemic to Italy; incidence is highest in the south and on the islands of Sardinia and Sicily (1). Recently, the use of molecular methods has enabled identification of other rickettsiae of the spotted fever group (SFG) from Ixodes ricinus ticks in northeastern Italy and in other areas of Europe (2-6). R. monacensis was identified as an etiologic agent of MSF-like illness in Spain (7).
