Malignant catarrhal fever (mcf) in bali cattle (bos javanicus) in a commercial farm in Malaysia

Malignant Catarrhal Fever (MCF) is a highly fatal disease of cattle and other ruminants with worldwide distribution. There are two forms of the disease: the first is caused by Alcephine herpesvirus-1 (AHV-1) and is derived from wildebeest wherelse the second form of the disease is associated with sheep and is caused by Ovine herpesvirus-2 (OHV-2). All cases were collected from the same farm where cattle (including Bali Cattle) and sheep were raised together. The infected animals showed clinical signs of severe depression, anorexia, fever, hypersalivation, eyes discharge and corneal opacity. Histopathologically, there was generalized vasculitis with perivascular cuffing lesion detected in all post-mortem cases. It is possible from the history, clinical signs and histological finding, that MCF in Bali Cattle, in this case, was associated with sheep. The aim of this study is to describe the clinical signs and pathological findings of 12 MCF affected animals
