[3Autochthonous cases of murine typhus in France?].

Three men native from Northern Africa, aged more than 40 years, but by their profession in France with narrow contacts to rats, present clinical signs of typhus. Serology (FCT and FAT) gives positive results with R. prowazeki and R. typhi which have a strait antigenic community. Following assays of absorption of the sera by the two antigens and light differences of titers we conclude that two cases are Brill-Zinsser illnesses, but one is really an autochtone case of murin typhus. The last affirmation is confirmed by the detection of specific IgM-antibodies.
