Rickettsia mongolotimonae: a rare pathogen in France

We report a second case of laboratory-confirmed infection caused by Rickettsia mongolotimonae in Marseille, France. This rickettsiosis may represent a new clinical entity; moreover, its geographic distribution may be broader than previously documented. This pathogen should be systematically considered in the differential diagnosis of atypical rickettsioses, especially rashless fevers with lymphangitis and lymphadenopathy, in southern France and perhaps elsewhere.
