Rickettsia felis is an exclusively cytozoic Gram-negative prokaryote with cat fleas as the major vectors.[1]As early as 1918,Rickettsia felis was detected in cat fleas in Europe and named Rickettsia ctenocephali.[2]Symptoms of fever,malaise,headache,maculopapular rash and eschar are observed in patients with Rickettsia felis infection.
