Neoehrlichiosis is a disease caused by the intracellular pathogen Neoehrlichia mikurensis. It usually presents with symptoms such as fever and vascular complications of unclear origin, e.g., thromboembolisms.[1][2]

The disease is diagnosed using a Neoehrlichia mikurensis-specific PCR.[3] Because Neoehrlichia mikurensis is an intracellular bacteria, cultivation on cell-free media and other routine microbiological methods can not be utilised for detection. This difficulty, along with being a relatively unknown disease, leads to many cases going undiagnosed for months or years, or even unrecognised entirely.[4]
Previously, it was believed that neoehrlichiosis only affected immunocompromised patients,[3] but more recent studies indicate that otherwise healthy individuals may also be susceptible.[2][5][6][7]
