Preliminary study of natural reservoirs as sentinels of Anaplasma phagocytophilum and Ehrlichia chaffeensis in Soria, northern Spain [PDF]

, 2013
The serum of foxes and red deer from the Prov- ince of Soria (northern Spain) was screened in indirect immunofluorescence assays to deter- mine whether these animals could be used as sentinels of the tick-borne pathogens Anaplas- ma phagocytophilum and ...

Detection of Borrelia lusitaniae, Rickettsia sp. IRS3, Rickettsia monacensis and Anaplasma phagocytophilum in Ixodes ricinus collected in Madeira Island, Portugal [PDF]

, 2008
A total of 300 Ixodes ricinus ticks were tested by polymerase chain reaction (PCR) for the presence of Borrelia spp., Rickettsia spp., and Anaplasma phagocytophilum. Sequence analysis demonstrated 8 (2.7%) ticks infected with B. lusitaniae, 60 (20%) with

Latent Neoehrlichia mikurensis Infections May Be Reactivated in Patients With B‐Cell Lymphomas Treated With Rituximab

Immunology, EarlyView.
Eight percent of this cohort of patients had a latent Neoehrlichia mikurensis infection. It was only the latently infected patients who had N. mikurensis‐specific T cells, not the matched B‐cell lymphoma patients without the infection. The T‐cell responses of latently infected patients included perforin‐expressing Th1 and CD8+ T cells that upregulated ...

Prevalence of Anaplasma phagocytophilum infection and effect on lamb growth [PDF]

, 2011
Background A major challenge in sheep farming during the grazing season along the coast of south-western Norway is tick-borne fever (TBF) caused by the bacteria Anaplasma phagocytophilum that is transmitted by the tick Ixodes ricinus. Methods A study was

Rickettsiales in South America: A Systematic Review of Their Molecular Detection and Distribution in Arthropods and Vertebrates

Public Health Challenges, Volume 5, Issue 2, June 2026.
ABSTRACT Bacteria of the order Rickettsiales comprise a diverse group of obligate intracellular microorganisms that are globally distributed and highly prevalent in tropical and subtropical regions. In South America, these bacteria have been associated with arthropod vectors, such as ticks, fleas, mites, lice, and certain dipterans, as well as with a ...

Anaplasma phagocytophilumInfection Induces Protracted Neutrophil Degranulation [PDF]

Infection and Immunity, 2004
ABSTRACTAnaplasma phagocytophilum-infected neutrophil degranulation could exacerbate inflammation. Thus, the degranulation of infected neutrophils was assayed. Infected neutrophils expressed CD11b and CD66b, and supernatants of infected neutrophils showed more proMMP-9 and MMP-9 activity than controls and continued to do so for ≥18 h.
