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 ...
