Investigation of Anaplasma marginale Seroprevalence in a Traditionally Managed Large California Beef Herd

Veterinary Medicine International, 2016
Recent observations by stakeholders suggested that ecosystem changes may be driving an increased incidence of bovine erythrocytic anaplasmosis, resulting in a reemerging cattle disease in California.

Molecular and serological detection of Anaplasma spp. in small ruminants in an area of Cerrado Biome in northeastern Brazil

Ticks and Tick-Borne Diseases
Anaplasmosis, caused by bacteria of the genus Anaplasma, is an important tick-borne disease that causes economic losses to livestock farms in many countries. Even though Anaplasma spp.

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

Blood Protozoan Infection Disrupts Ovarian Follicular Development in Dairy Cattle: A Mechanistic Link to Reproductive Failure

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Subclinical haemoprotozoan infection disrupts RBC integrity, and that leads to decreased Hb level and excess free iron in plasma. That subsequently impairs ovarian follicular development and thereby builds up a mechanistic link to reproductive failure in dairy cattle.

Anaplasma marginale Infection of Dermacentor andersoni Primary Midgut Cell Culture Is Dependent on Fucosylated Glycans

Frontiers in Cellular and Infection Microbiology, 2022
Tick midgut is the primary infection site required by tick-borne pathogens to initiate their development for transmission. Despite the biological significance of this organ, cell cultures derived exclusively from tick midgut tissues are unavailable and ...

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 ...
