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.

Genetic Diversity of Theileria parva and Anaplasma spp. Isolated From Ticks Collected From Kiambu County, Kenya

BioMed Research International, Volume 2026, Issue 1, 2026.
Environmental changes and human activities such as deforestation and expansion of agricultural land are increasing tick‐borne diseases including Anaplasmosis, Babesiosis, Ehrlichiosis, and Theileriosis. These diseases, which affect animals, can be transmitted to humans through tick bites.

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

An Integrative Assessment of Tabanus rubidus (Diptera: Tabanidae) in Thailand: Distribution, Population Genetics, and Pathogen Surveillance

Journal of Tropical Medicine, Volume 2026, Issue 1, 2026.
Tabanus rubidus (Diptera: Tabanidae) is a significant species of the Tabanidae family, known for its veterinary and medical relevance, and is found across Thailand. This study examines the species distribution, genetic diversity, demographic history, and vector‐pathogen transmission of T.

A One Health Assessment of Tick and Tick‐Borne Pathogen Diversity and Zoonotic Risk in Hubei Province, Central China

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Ticks and tick‐borne pathogens (TBPs) threaten livestock productivity and public health worldwide, and climate–land‐use change is expanding vector habitats, elevating tick‐borne disease risk. However, TBP diversity and risk in Hubei Province, central China, remain insufficiently defined within a One Health framework.

Spatial Heterogeneity of Tick‐Borne Pathogens Outpaces Genetic Structuring in Anatolian Dermacentor reticulatus Populations

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Understanding how vector population structure influences pathogen circulation remains a major challenge in tick‐borne disease ecology, particularly in biogeographically transitional regions. Dermacentor reticulatus, a widespread Palearctic tick species and vector of multiple pathogens, provides a useful system to investigate this relationship in a ...

Detection of Multiple Microorganisms in Ruminant Ticks in Senegal Using High‐Throughput Microfluidic Real‐Time PCR

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Ticks are major vectors of numerous pathogens affecting both livestock and humans. In Senegal, data on the diversity of tick‐borne pathogens (TBPs) in ruminant‐associated ticks remain limited. In total, 1703 ticks were collected from goats, sheep, and cattle across three ecological zones of Senegal (Sudanian, Sahelian, and Sudano‐Sahelian).
