First study on molecular identification of Anaplasma ovis in sheep in southern Kazakhstan [PDF]

Veterinary World
Background and Aim: Anaplasmosis in small ruminants is a tick-borne infection caused mainly by the obligate intraerythrocytic bacterium Anaplasma ovis. It is usually subclinical, with persistent infection in affected animals, but acute disease can occur,

Detection of Multiple Microorganisms in Ruminant Ticks in Senegal Using High-Throughput Microfluidic Real-Time PCR. [PDF]

Transbound Emerg Dis
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).
