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 ...

Microscopic-Serologic Survey of Anaplasma marginale Rickettsia in Buffaloes in Al-Qadisiyah and Babylon Governorates, Iraq

, 2019
The aim of the present study was to detect the prevalence of Anaplasma marginale in buffaloes in two Iraqi governorates, Al-Qadisiyah and Babylon, by the microscopy as well as the competitive-ELISA that used firstly among the Iraqi buffaloes.

Direct PCR-RFLP based detection and differentiation of Anaplasma species in naturally infected goats of eastern Haryana, India

Indian Journal of Animal Sciences, 2019
The present investigation was designed to develop a novel, rapid and cost effective direct PCR-RFLP assay, as a specific diagnostic tool for detection and differentiation of two Anaplasma species (A. ovis and A. marginale).

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.

Growth of Cowdria ruminantium, the causative agent of heartwater, in a tick cell line [PDF]

, 2000
The tick-borne rickettsia Cowdria ruminantium has been propagated continuously for over 500 days in the Ixodes scapularis tick cell line IDE8 by using the Gardel isolate from bovine endothelial cells as an inoculum.

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

Genetic diversity of Anaplasma marginale strains from an outbreak of bovine anaplasmosis in an endemic area

, 2008
Anaplasma marginale is a tick-borne pathogen of cattle that causes the disease bovine anaplasmosis worldwide. Major surface proteins (MSPs) are involved in host–pathogen and tick–pathogen interactions and have been used as markers for the genetic ...
