An in‐house nucleic acid test for detection of Anaplasma phagocytophilum in whole blood donor samples

Transfusion, Volume 66, Issue 6, Page 1122-1129, June 2026.
Abstract Background Anaplasma phagocytophilum is a tick‐borne pathogen that causes anaplasmosis. Increased incidences of this disease in Canada and cases of transfusion‐transmitted anaplasmosis in the United States have been reported. Currently, there are no Health Canada licensed methodologies available for detection of A.

Serological diagnosis of persistent infection with Anaplasma marginale bacteria in cattle

The Iraqi Journal of Veterinary Medicine, 2015
Bovine anaplasmosis is one of the tick-borne diseases caused by Anaplasma marginale bacteria which can cause high economic losses to livestock. Cattle that recovered from acute infection become carriers without clinical signs related to the disease and ...

Antigenic characterization of Brazilian isolates of Anaplasma marginale [PDF]

Memórias do Instituto Oswaldo Cruz, 2003
Antigenic characterization of Anaplasma marginale isolates, by identifying conserved and variable epitopes of major surface proteins (MSP), is an important tool for vaccine development against this rickettsia. The B cell epitopes of A. marginale isolates from three microregions of the State of Pernambuco and one from the State of Mato Grosso do Sul ...

Tick‐borne pathogen interactions enhance transmission in cattle and ticks in Ogun, Nigeria

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Tick‐borne diseases (TBDs) pose a major public health concern in tropical regions, where co‐infections and pathogen interactions complicate disease control. Understanding how these interactions vary across vertebrate hosts and tick vectors, and their impact on disease transmission, is crucial for developing effective intervention strategies ...

Ticks and tick‐borne bacterial pathogens found on hard ticks (Acari: Ixodidae) on cattle in the Central River region of The Gambia

Medical and Veterinary Entomology, Volume 40, Issue 1, Page 91-100, March 2026.
First detection of Ehrlichia minasensis, Anaplasma marginale and hemotropic Mycoplasma spp. in cattle in The Gambia. Identification of four tick species, with Hyalomma marginatum being the most common. 15.6% of ticks tested positive for tick‐borne pathogens, including Ehrlichia spp., A. marginale and hemotropic Mycoplasma spp.

Co-infections with multiple genotypes of Anaplasma marginale in cattle indicate pathogen diversity

Parasites & Vectors, 2018
Background Only a few studies have examined the presence of Anaplasma marginale and Anaplasma centrale in South Africa, and no studies have comprehensively examined these species across the whole country. To undertake this country-wide study we adapted a

Acaricidal activity of small molecule antagonists of the tick kinin receptor against Rhipicephalus microplus acaricide‐susceptible and resistant strains

Pest Management Science, Volume 82, Issue 2, Page 1618-1628, February 2026.
Two small molecules, SACC‐0039590 and SACC‐0428788, killed cattle fever tick, R. microplus, susceptible Deutch strain and pyrethroid resistant Arauquita strain larvae. SACC‐0039590 at 1 mM decreased the reproductive parameters of Deutch females. Abstract BACKGROUND Resistance to acaricides underscores the need for tick control alternatives.

Rickettsia Bellii and Anaplasma Marginale

, 2023
Anaplasma marginale is an obligate intracellular gram-negative bacterial pathogen of ruminants. It is the etymological agent of bovine anaplasmosis, which is the most prevalent tick-borne cattle disease in the word. Despite its prevalence and severe economic impacts, few effective control measures exist for A. marginale. Antibiotic treatment, acaricide
