boutonneuse fever[′büt·ən‚üz ‚fē·vər]
(also Marseilles fever), an acute infectious disease of the rickettsioses group, accompanied by a rash on the torso, face, and limbs. The causative agent, Rickettsia conorii, is transmitted by the bite of the dog tick Rhipicephalus sanguineus. Boutonneuse fever was first discovered in Tunis in 1910 and later in the countries of the Mediterranean basin and on the Black Sea coast of Rumania and Turkey. In the USSR it is found on the shores of the Black and Caspian seas, usually in the summer (May to September). Prevention consists in destroying dog ticks.
