"Neoehrlichiosis" Internationally Diagnosed And Successfully Treated In Patients Without Immunodeficiency For The First Time

The intercellular bacteria "Candidatus Neoehrlichia", as e.g. Borrelia, can be transferred by ticks. Approx. 4.2 % of indigenous ticks are infected with this rarely explored bacterium which, until today, has been exclusively identified as pathogenic bacterium in patients with an impairment of the immune system, such as in case of leukaemia, rheumatism or after organ transplantation.
