Anaplasma ovis as the suspected cause of mortality in a neonatal elk calf [PDF]

Journal of Veterinary Diagnostic Investigation, 2019
Anaplasma ovis infection is known to occur in elk experimentally, but without clinical signs or significant clinicopathologic changes. An elk farm in southern Indiana experienced the death of 3 neonates. Gross findings suggested hemolytic anemia as the cause of death.

Molecular epidemiology and genetic diversity of Anaplasma and Theileria spp. in Pakistani sheep.

PLoS ONE
Pakistan has a huge sheep population (37.2 million in 2024) that is largely unexplored for the presence of vector transmitted parasites. Present study was aimed to document the prevalence of Anaplasma sp., Anaplasma ovis, Theileria ovis and Theileria ...

First report of Anaplasma marginale and Anaplasma ovis in goats in Kelantan, Malaysia

Tropical Biomedicine
Anaplasma species are obligate rickettsial intraerythrocytic pathogens that cause an important tick-borne disease of economic importance in livestock production in many countries. Anaplasma species have been detected from farm animals worldwide, there is a paucity of information on Anaplasma infections in goats from Malaysia.

Epidemiology and genetic diversity of Anaplasma ovis in goats in Corsica, France

Parasites & Vectors, 2019
Anaplasma ovis est une cause majeure d'anaplasmose des petits ruminants, une maladie transmise par les tiques qui touche principalement les petits ruminants dans les régions tropicales et subtropicales du monde. En raison de problèmes de santé et de production dans les troupeaux de chèvres laitières en Corse, en France, et de la démonstration de l ...

Tick‐Tac‐Foe: When Ticks, Trade, and Zoonotic Pathogens Align in African Wet Meat Markets

Public Health Challenges, Volume 5, Issue 2, June 2026.
ABSTRACT Zoonotic diseases account for over ∼60% of infectious diseases and present a significantly growing fatality threat in Africa. Live and wet markets (LWMs) in Africa function as key economic venues that support human livelihoods through social interaction and trade in food stuff, including meat and other animal‐based products.

First serological and molecular evidence on the endemicity of Anaplasma ovis and A. marginale in Hungary [PDF]

Veterinary Microbiology, 2007
Recurring and spontaneously curing spring haemoglobinuria was recently reported in a small sheep flock in a selenium deficient area of northern Hungary. In blood smears of two animals showing clinical signs, Anaplasma-like inclusion bodies were seen in erythrocytes. To extend the scope of the study, 156 sheep from 5 flocks and 26 cattle from 9 farms in

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.
