Bovine anaplasmosis is a hemolytic disease of cattle caused by the rickettsia Anaplasma marginale transmitted by arthropods. In the US, the presence of anaplasmosis has been reported in almost all states. This wide distribution may be due to increased livestock transport and, therefore, the opportunity for mechanical transmission by persistently infected asymptomatic livestock.

Bovine anaplasmosis causes significant economic losses in most countries, mainly due to its high morbidity and mortality in susceptible herds.

Control measures against anaplasmosis

Disease control measures have not changed much over the past few decades. They vary by geographic location and include arthropod control through acaricides, antibiotic administration, and vaccination.
