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 ...

Integrative Genomics Identifies Candidate Genes Underlying Trypanotolerance in Hybrid African Cattle

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT Integrative genomics combines data from different omics sources to link genotypes and phenotypes with the aim of unravelling biological networks and pathways that undergird complex traits, particularly with respect to disease. In this respect, integrative genomics, leveraging population and functional genomic data, can be employed to ...

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 ...

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 ...

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 ...

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.
