Molecular Characterization and Prevalence of Anaplasma ovis and Anaplasma phagocytophilum in Goat Population in Siirt Province From Türkiye

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This study assessed the molecular prevalence and genetic characterization of Anaplasma ovis and Anaplasma phagocytophilum in goats from Siirt using MSP4‐based PCR and sequencing; a high prevalence of A. ovis (52.0%) was detected with significant risk factor associations, while A. phagocytophilum was not identified; phylogenetic analysis showed that the

Molecular Characterization of Aegyptianella pullorum ( Rickettsiales , Anaplasmataceae ) [PDF]

Journal of Clinical Microbiology, 2003
ABSTRACT We sequenced the 16S rRNA and groEL genes of Aegyptianella pullorum , a small bacterium that infects and replicates only in avian red blood cells. A specific PCR test was developed to analyze A. pullorum DNA.

Molecular Survey of Babesia and Anaplasma Infection in Cattle in Bolivia

Veterinary Sciences, 2021
Latin American countries produce more than a quarter of the world’s beef and are a major global supplier of livestock protein. Tick-borne diseases (TBDs) are a major constraint to the livestock industry worldwide, including in Latin America.

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 ...

Detection of new Anaplasmataceae in the digestive tract of fish from southeast Asia [PDF]

Clinical Microbiology and Infection, 2009
The bacteria of the genus Neorickettsia are strict intracellular bacteria of the Anaplasmataceae family. They are transmitted to their definitive host (humans and animals) by ingestion of raw fish, snails or aquatic insects that are parasitised by infected trematodes. Among them, three species (N. sennetsu, N. helminthoeca and N. risticii) are known to

A novel candidate species of Anaplasma that infects avian erythrocytes

Parasites & Vectors, 2018
Background Anaplasma spp. are Gram-negative obligate intracellular bacteria transmitted by ticks. Even though numerous studies have detected DNA from Anaplasma spp.

Screening and phylogenetic characterization of tick-borne pathogens in a population of dogs and associated ticks in Egypt

Parasites & Vectors, 2022
Highlights Traditional and molecular techniques were used to screen domestic dogs and attached ticks for TBPs. A wide range of TBPs in dogs and attached ticks was detected in Egypt. Some accidental pathogens, such as 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 ...
