Abstract

A human case of rickettsial infection occurred in Sicily following tick bite. The patient did not have fever, the typical nodular rash, or other symptoms of illness other than development of a tache noire containing spotted fever group rickettsiae which were demonstrated by immunofluorescence. A high titer of antibodies of the IgG class suggests that the patient may have had previous exposure to Rickettsia conorii, or a related spotted fever group rickettsia. An anamnestic response may be hypothesized to have conferred partial immunity, with resulting containment of rickettsiae at the site of inoculation.
