ABSTRACT
In Europe, human infections with “
Candidatus
Neoehrlichia mikurensis” have mainly been restricted to immunocompromised patients. We report here the first cases of asymptomatic “
Ca
. Neoehrlichia mikurensis” infection in immunocompetent humans (5/316 [1.6%] were infected). Due to the potential threats of infections with “
Ca
. Neoehrlichia mikurensis” in healthy persons to the safety of the blood supply, further study of this phenomenon is required.
