title: Rickettsia felis infection in Sweden: report of two cases with subacute meningitis and review of the literature.
abstract: Two patients with headache and pleocytosis were diagnosed with Rickettsia felis infection using a polymerase chain reaction of cerebrospinal fluid and serological testing. Sequencing of the amplified products showed that they were 99-100% homologous to R. felis. These cases add to our knowledge of the clinical manifestations, as well as the geographical distribution, of this spotted fever agent.
