Fever of Unknown Origin, a Vascular Event, and Immunosuppression in Tick-Endemic Areas: Think About Neoehrlichiosis. [PDF]

Cureus, 2023
Three patients were referred to our hospital because of fever of unknown origin (FUO) and thrombosis or thrombophlebitis. All of them had been under immunosuppression (IS) with rituximab. Intensive diagnostics for FUO and blood cultures remained negative. Finally, the association of fever, immunosuppression, and a vascular event led to the suspicion of

Development and performance evaluation of a clinical metagenomics approach for identifying pathogens in the whole blood from patients with undifferentiated fever. [PDF]

Front Cell Infect Microbiol
Introduction: Blood culture is the cornerstone of microbiological diagnostics for patients with acute undifferentiated fever and no obvious localization of infectionhowever, up to 50% of cases remain undiagnosed.

Ticks and Tick-Borne Pathogens Encountered by Dogs and Cats: A North European Perspective. [PDF]

Transbound Emerg Dis
Climate change is increasing the worldwide burden of tick‐borne diseases (TBDs). Dramatic increases in human cases of borreliosis have been reported during the past few decades, including from Finland, located in North Europe. As human exposure to ticks carrying pathogens is increasing, so likely is exposure of dogs and cats.

Neoehrlichia mikurensis—An emerging opportunistic tick‐borne infection in immunosuppressed patients

Journal of Internal Medicine, Volume 293, Issue 6, Page 782-790, June 2023., 2023
Abstract Background Neoehrlichia mikurensis (N. mikurensis) is a newly discovered tick‐borne pathogen that can inflict life‐threatening illness in immunocompromised patients. N. mikurensis infection is only detectable by polymerase chain reaction (PCR)‐based methodologies. We describe three distinct clinical manifestations of N.

Infection with Neoehrlichia mikurensis promotes the development of malignant B‐cell lymphomas

British Journal of Haematology, Volume 201, Issue 3, Page 480-488, May 2023., 2023
Summary The tick‐borne pathogen Neoehrlichia (N.) mikurensis is implicated in persistent infection of the vascular endothelium. B cells are crucial for the host defence to this infection. Chronic stimulation of B cells may result in B‐cell transformation and lymphoma. Five patients with malignant B‐cell lymphoma and concomitant N.

Evaluation of Disease Causality of Rare Ixodes ricinus-Borne Infections in Europe

Pathogens, 2020
In Europe, Ixodes ricinus ticks transmit pathogens such as Borrelia burgdorferi sensu lato and tick-borne encephalitis virus (TBEV). In addition, there is evidence for transmission to humans from I. ricinus of Anaplasma phagocytophilum, Babesia divergens,

First evidence of Candidatus Neoehrlichia mikurensis in Hungary [PDF]

, 2013
Altogether 2004 Ixodes ricinus ticks, from 37 places in Hungary, were analysed in pools with a recently developed multiplex real-time PCR for the presence of Candidatus Neoehrlichia mikurensis and for other representatives of the genus. Ca.
