Electron microscopic view of Lyssavirus

Lyssaviruses are a group of single-stranded RNA viruses which cause rabies in cattle.

The single-stranded RNA molecule that encodes five viral proteins: polymerase L, matrix protein M, phosphoprotein P, nucleoprotein N, and glycoprotein G, which form a separate monophyletic lineage consisting of sub-lineages A and B[1]. Genetic markers on the Lyssavirus indicates a possible variation between geographic regions, although the biologically active regions are conserved[2].

In cattle, Lyssaviral antigens are most prominent in the brainstem, followed by the cerebellum[3].
