Molecular detection of Anaplasma marginale in Arabian Camels (Camelus dromedarius) in Riyadh, Saudi Arabia

Journal of the Saudi Society of Agricultural Sciences, 2022
Anaplasmosis, an underestimated tick-borne disease, is a common infection in ruminants including Arabian camels. To our knowledge, few studies have been carried out in Saudi Arabia to identify via molecular methods Anaplasma spp.

Serologic Cross-Reactivity between Anaplasma marginale and Anaplasma phagocytophilum [PDF]

Clinical and Vaccine Immunology, 2005
ABSTRACT In the context of a serosurvey conducted on the Anaplasma marginale prevalence in Swiss cattle, we suspected that a serological cross-reactivity between A. marginale and A. phagocytophilum might exist. In the present study we demonstrate that cattle,

Coinfection of cattle in Virginia with Theileria orientalis Ikeda genotype and Anaplasma marginale

bioRxiv, 2021
Theileria orientalis Ikeda is a newly identified agent of bovine infectious anemia in the United States. Although T. orientalis Ikeda is transmitted by ticks other than the tick that transmits Anaplasma marginale—a bacterial etiology of bovine infectious

Molecular prevalence of Anaplasma marginale and associated risk factors in beef cattle herds from Ohio: a cross-sectional study.

Journal of the American Veterinary Medical Association, 2022
OBJECTIVE To estimate the prevalence of Anaplasma marginale, the causative agent of bovine anaplasmosis, in beef herds from Ohio; evaluate farm identity and animal age as risk factors; and examine serologic cross-reactivity with Anaplasma phagocytophilum,

Seasonal Investigation of Anaplasma marginale Infection in Pakistani Cattle Reveals Hematological and Biochemical Changes, Multiple Associated Risk Factors and msp5 Gene Conservation

Pathogens, 2022
Bovine anaplasmosis is a tick-borne disease caused by an obligate intercellular Gram-negative bacterium named Anaplasma (A.) marginale. In this study, we report the seasonal prevalence, potentially associated risk factors and phylogeny of A. marginale in

Functional and Immunological Relevance of Anaplasma marginale Major Surface Protein 1a Sequence and Structural Analysis. [PDF]

, 2013
Bovine anaplasmosis is caused by cattle infection with the tick-borne bacterium, Anaplasma marginale. The major surface protein 1a (MSP1a) has been used as a genetic marker for identifying A.

Transformation of Anaplasma marginale

Veterinary Parasitology, 2010
The tick-borne pathogen, Anaplasma marginale, has a complex life cycle involving ruminants and ixodid ticks. It causes bovine anaplasmosis, a disease with significant economic impact on cattle farming worldwide. The obligate intracellular growth requirement of the bacteria poses a challenging obstacle to their genetic manipulation, a problem shared ...
