Eye Ring. Bovine malignant catarrhal fever (BMCF) is a fatal lymphoproliferative disease [1] caused by a group of ruminant gamma herpes viruses including Alcelaphine gammaherpesvirus 1 (AlHV-1) [2] and Ovine gammaherpesvirus 2 (OvHV-2) [1] [3] These viruses cause unapparent infection in their reservoir hosts (sheep with OvHV-2 and wildebeest with AlHV-1), but are usually fatal in cattle and ...
Vaccines against Theileria are in development. [ 1 ] [ 8 ] In May 2010, a vaccine that was reported to protect cattle against East Coast fever had been approved and registered by the governments of Kenya, Malawi, and Tanzania.
Some vaccines that rely on erythrocyte-derived antigen sources provide immunity or prevent clinical disease, although these do not prevent cattle from being infected with A. marginale. Other means of prevention can include testing all ruminants in a herd and eliminating any individuals who test positive for anaplasmosis, leading to an ...

[4] Acaricides and pyrethroids are commonly used however this has led to the development of acaricide-and pyrethroid-resistances. [2]
