ABSTRACT
Rickettsia felis is a flea-transmitted pathogen however, in Greece, much work has been done on another flea-borne pathogen, R. typhi; human cases have been described and high-risk areas have been characterized. Nevertheless, little is known about human infections caused by R. felis in the country since human cases are not routinely tested for antibodies against this pathogen. During the past seven years, we have set up a protocol at the National Reference Centre in order to improve the testing of tick-borne diseases in Greece. Based on this protocol, R. conorii, R. typhi R. slovaca, R. felis, and R. mongolotimonae have been added into the routine analysis; during these last years, eight (8) cases of potential exposure to R. felis were identified by serology. On an environmental investigation carried out at the residences of the patients, the pathogen was detected in C. felis only. The demonstration of R. felis potential presence highlights the need for better testing and surveillance of the pathogen.
