Rickdettsia sp. 364D Causing a Cluster of Eschar-associated Illness
Pediatric Infectious Disease Journal
We describe the clinical course of the first 3 pediatric cases infected with Rickettsia spp. 364D. Although the pathogen was identified in California ticks decades ago, only recently have human cases been documented. Clinical features are generally mild, characterized by eschar, fever, headache, malaise and lymphadenopathy. Antigenic similarity among rickettsiae leads to cross-reactive antibody responses; definitive diagnosis requires molecular methods.
