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 ...

Human Granulocytic Anaplasmosis andAnaplasma phagocytophilum

Emerging Infectious Diseases, 2005
Human granulocytic anaplasmosis is a tickborne rickettsial infection of neutrophils caused by Anaplasma phagocytophilum. The human disease was first identified in 1990, although the pathogen was defined as a veterinary agent in 1932. Since 1990, US cases have markedly increased, and infections are now recognized in Europe.

Tick‐Tac‐Foe: When Ticks, Trade, and Zoonotic Pathogens Align in African Wet Meat Markets

Public Health Challenges, Volume 5, Issue 2, June 2026.
ABSTRACT Zoonotic diseases account for over ∼60% of infectious diseases and present a significantly growing fatality threat in Africa. Live and wet markets (LWMs) in Africa function as key economic venues that support human livelihoods through social interaction and trade in food stuff, including meat and other animal‐based products.

Detection of Anaplasma phagocytophilum in wild boar in Slovenia [PDF]

Clinical Microbiology and Infection, 2009
Human granulocytic anaplasmosis (HGA) comprises a group of emerging tick-borne infectious diseases and it is caused by the intracellular bacteria, Anaplasma phagocytophilum. Infections with Anaplasma spp. have been described in humans and animals. Many studies have been performed to elucidate the natural cycle of A.

Molecular detection of Anaplasma infections in ixodid ticks from the Qinghai-Tibet Plateau

Infectious Diseases of Poverty, 2019
Anaplasma species are tick-transmitted obligate intracellular bacteria that infect many wild and domestic animals and humans. The prevalence of Anaplasma spp. in ixodid ticks of Qinghai Province is poorly understood.

Molecular Detection of Anaplasma Phagocytophilum as a Zoonotic Agent in Owned and Stray Dogs in Tehran, Iran [PDF]

Archives of Razi Institute, 2019
The genus Anaplasma is an obligated intracellular Rickettsia and among its species, Anaplasma phagocytophilum (A. phagocytophilum) is a zoonotic agent that infects host neutrophils. The aim of this study was molecular detection of A.

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

Immunology, Volume 178, Issue 2, Page 307-317, June 2026.
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 ...

Circulation of four Anaplasma phagocytophilum ecotypes in Europe [PDF]

Parasites & Vectors, 2014
Anaplasma phagocytophilum is the etiological agent of granulocytic anaplasmosis in humans and animals. Wild animals and ticks play key roles in the enzootic cycles of the pathogen. Potential ecotypes of A. phagocytophilum have been characterized genetically, but their host range, zoonotic potential and transmission dynamics has only incompletely been ...

Molecular detection of Anaplasma species in dogs in Colombia

Revista Brasileira de Parasitologia Veterinária
Anaplasma platys and A. phagocytophilum are tick-borne pathogens that parasitize platelets and neutrophils, respectively, of humans and animals. The former is the etiological agent of canine cyclic thrombocytopenia, while the latter is that of canine ...
