Background: Ehrlichiosis is a clinically important, emerging zoonosis. Only Ehrlichia chaffeensis and E. ewingii have been thought to cause ehrlichiosis in humans in the United States. Patients with suspected ehrlichiosis routinely undergo testing to ensure proper diagnosis and to ascertain the cause.

Methods: We used molecular methods, culturing, and serologic testing to diagnose and ascertain the cause of cases of ehrlichiosis.

Results: On testing, four cases of ehrlichiosis in Minnesota or Wisconsin were found not to be from E. chaffeensis or E. ewingii and instead to be caused by a newly discovered ehrlichia species.

All patients had fever, …

Anaplasmataceae As Human Pathogens : Biology, Ecology And Epidemiology, Marina E. Eremeeva, Gregory A. Dasch

Environmental Health Sciences Faculty Publications

This review describes the biology, ecology, and epidemiology of known human pathogens in the family Anaplasmataceae that are transmitted by ticks and belong to the genus Anaplasma and genus Ehrlichia. We discuss the current status of diagnosis and surveillance of the diseases they cause, and address the challenges and new perspectives raised due to continuous recognition of new emerging human pathogens in the family Anaplasmataceae.
